ILO Ports

ILO is a small microcontroller in the server, which is running even when the server is powered off. It stops only when you pull all the power cables out. The microcontroller can even command the server to reset, power off or power on. You can also remotely access the server's display and keyboard through the ILO controller.

If the server crashes or has hardware problems, you can connect to the server through ILO, command the server to restart and then watch the BIOS messages to see what kind of maintenance is needed. This is very useful if the server is in a faraway location.

The ILO network port is for remote management of the server: if you connect to the ILO port, you can access the server through ILO. However, the programs running in the server cannot make connections through the ILO network port.

When the server is booting, ILO will prompt you to press a key (F8, I think) to change ILO settings. From there, you can set up network addresses, usernames and passwords for ILO connection. For operating systems that allow text-based access (Linux, SCO Unix and such like) this is all you need to be able to manage your server remotely. If you need graphics-based remote access, you need to install ILO drivers for your OS to be able to control the OS remotely through ILO.

how to add bluetooth devices in windows7

he process of adding Bluetooth devices in Windows 7 is very different from adding them in Windows Vista. In this article, I will walk you through the process of adding a Bluetooth device in Windows 7 as well as give you some "gotchas" to watch out for so that the process runs smoothly.
Recently, I bought a new Sony Vaio laptop that included a rebate for a free Bluetooth mouse and Windows 7. I enjoyed using the laptop for a couple of months before Windows 7 was released and these items arrived. In that time, I had used a small laptop USB mouse that works pretty well. Honestly, I may never have bought the Bluetooth mouse if it was not free. Still, I was interested in it enough to spend some significant time making it work. Perhaps it was the challenge of something new, that the mouse looked sleek and cool, or that I just was stubborn enough to make sure I got my free mouse working. No matter as, in the end, I got it working and am thankful that I did as this Bluetooth mouse is cool in every way and I would never go back to the old USB mouse.

Bluetooth devices 101

Today, everyone is familiar with Bluetooth thanks to Bluetooth headsets that are very popular on cellular phones. Bluetooth is wireless networking but it is short distance. Technically, when you use Bluetooth networking you are creating a Personal Area Network, or PAN. Other than those Bluetooth headsets that make peoples' ears look like they are on Star Trek, there are a wide variety of Bluetooth devices. All you have to do is to look in the Bluetooth product directory and you will find that there are thousands of Bluetooth devices out there.
Besides the cellular phone headset, I would think that the second most common device is the Bluetooth mouse that many people use on a laptop. Adding one should be easy, right? Well, there may be more to it than you might think.

Flashback to Windows Vista Bluetooth

Back in the "old" Windows Vista (Vista must be old now as Windows 7 is out, right?), to add a Bluetooth device you would simply go to Control Panel and click on Bluetooth Devices, as you see in Figure 1.

Figure 1: Windows Vista Bluetooth Devices
From there you could click on either Add Wireless Device or Bluetooth Settings. What could be easier, right?
In Windows 7 that simple process has been changed in the name of progress. Let me show you how...

Adding a Bluetooth Mouse to Windows 7, step by step

To add a Bluetooth device in Windows 7, you do go to Control Panel but, from there, the water gets a little murky. The first time I went there to add my Bluetooth device, I was not sure what to do so I had to use the Search function and search for the word Bluetooth in order to find the option to add a Bluetooth device. Still, you should not have to do that.
Instead, what you need to do is to click on View Devices and Printers under Hardware and Sound, as you see in Figure 1.

Figure 2: Control Panel in Windows 7
From there, you will be taken to Devices and Printers, which (with the word printers in there), seems like a strange place to go to add a Bluetooth mouse.

Figure 3: Adding a new Bluetooth device in Windows 7
Next, before you click Add a device (shown in Figure 2) you should first do a few things:

1. Make sure that, if you have a laptop, wireless is enabled on the laptop (my Sony has a switch on the side). Bluetooth is wireless and, typically, when you disable all wireless that includes not only 802.11a/b/g/n but also Bluetooth.
2. Make sure that any proprietary software you have that controls power or wireless has Bluetooth enabled (I will cover this more in the "gotchas").
3. Turn on the power on the mouse and press the Connect button.

Now, you can click Add a Device and you should see something like the graphic in Figure 3.

Figure 4: Locating the device to add
Select the device you want to add and click Next.
The device drivers will be loaded and you should see the window in Figure 5.

Figure 5: Bluetooth mouse has been added
At this point, your mouse should be working. You can use it to click Close and you will be taken back to the Devices and Printers window where you can see your device.
Ideally, adding Bluetooth devices should be that easy but there are some "gotchas" to look out for.

"Gotchas" to Watch Out For When Adding Bluetooth Devices

To make sure that it goes as easily as I demonstrated above, look out for these potential pitfalls:

1. Make sure that your laptop or PC actually has Bluetooth. You can not assume that it has it.
2. Make sure that your Bluetooth is ON. Your laptop might have a switch that enables or disables wireless.
3. Make sure that any proprietary software you have that controls power or wireless has Bluetooth enabled. On my Sony Vaio, I have a proprietary software application installed (from Sony) called Smart Wi Connection Utility that enables and disables various types of wireless connections, including Bluetooth. I ran into an issue where Bluetooth was disabled here and I had to track down this utility to enable it.

Figure 6: SmartWi Connection Utility

4. Make sure that your Bluetooth device is powered on and make sure that it has some kind of LED indicating that it has power. While it may be obvious, that also means that your device has batteries that have a charge (fresh batteries are preferred).
5. You may have to press the Connect button on the Bluetooth device to get it talking to the Bluetooth adaptor on the PC or laptop.
6. Make sure that the drive for your Bluetooth device is successfully installed, as you see in Figure 7 and Figure 8.

Error: "Not enough storage is available to process this command" - In my case, this problem was caused by non paged pool space. Please follow these steps and check also the KBs to resolve the problem:

1. Set page pool size to 1.5x-3x of your RAM. For example for 1GB of RAM, set the page pool to a value between 1.5 and 3 GB.
2. Click Start, click Run, type regedit in the Open box, and then click OK. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management. On the Edit menu, point to New, and then click DWORD Value. Type PoolUsageMaximum as the entry name, and then press ENTER.  Right-click PoolUsageMaximum, and then click Modify. Click Decimal. In the Value data box, type 60, and then click OK.
Setting the value at 60 informs the Memory Manager to start the trimming process at 60 percent of PagedPoolMax rather than the default setting of 80 percent. If a threshold of 60 percent is not enough to handle spikes in activity, reduce this setting to 50 percent or 40 percent.
3. Click Start, click Run, type regedit in the Open box, and then click OK. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management. On the Edit menu, point to New, and then click DWORD Value. Type PagedPoolSize as the entry name, and then press ENTER. Right-click PagedPoolSize, and then click Modify. Click Hexadecimal. In the Value data box, type a value of FFFFFFFF, and then click OK. Setting PagedPoolSize to 0xFFFFFFFF allocates the maximum paged pool in lieu of other resources to the computer.
4. Quit Registry Editor.
5. Restart the server for the changes to take effect.

How To Use BranchCache in Windows 7

BranchCache is a network performance tool available in Windows 7 and Server 2008. It acts like a proxy in that it works only when requested by a client user. The typical user scenario where BranchCache will be useful is where a branch office has a slow link back to the central office. Any downloads that might occur will be slow because of the bandwidth connection. BranchCache is designed for such remote office operations.
There are two modes in which BranchCache works, hosted or distributed. In hosted mode, a 2008 server located on the branch office hosts the cached files. In Distributed Cache mode, a branch server is not necessary; file copies are directly cached onto the PC’s at the branch location.
When BranchCache is enabled, if there is a request for data across the network, a copy of the data or file is downloaded from the intranet website or a file server and it is cached locally within the branch office. As the need arises if another user in the branch requests the file, the user gets access to the content almost immediately as it is downloaded from the local cache rather than over a limited bandwidth connection back to headquarters.
How it works
BranchCache only pulls down data from headquarters as the need arizes; ie., only when the user requests it. Because it operates as a passive cache, it uses less bandwidth between headquarters and the branch. BranchCache only caches read requests, so it will never interfere with a user saving a file.  Both HTTP and HTTPS are supported by BranchCache.and file servers with server messaging block [SMB]).It also works with a variety of network security technologies like Secure Sockets Layer (SSL), SMB signing, and Internet Protocol security (IPsec).
Configuring BranchCache
BranchCache requires that you use Windows 7 PCs and Windows Server 2008 R2 servers.
You can use either Group Policy settings or the netsh command-line tool to perform the following configuration tasks on BranchCache clients:

• Enable BranchCache
• Select one of two modes: Distributed Cache or Hosted Cache.
• If using Distributed Cache mode specify the size of the client computers’ cache. BranchCache can use up to 5% of the hard disk drive for the cache.
• If using Hosted Cache mode specify the location where the Hosted Cache will reside.

Server 2008 R2 Configuration
BranchCache has to be installed on Windows Server 2008 R2. You must install the BranchCache feature using server manager. in order to configure a Web server or an application server that uses the Background Intelligent Transfer Service (BITS) protocol.
You must install the BranchCache for Network Files feature, and configure the server using Group Policy in order to configure a file server to operate with BranchCache. For a Windows Server 2008 R2 computer to act as a BranchCache client, you must first install the BranchCache feature and then follow the client configuration steps in this document.

To install the BranchCache feature
Click Start ->Administrative Tools -> Server Manager->Right Click Features -> Add Features.
Run the Add Features Wizard, select BranchCache, and then click Next.

Server Branch Cache Configuration

In the Confirm Installation Selections dialog box, click Install.
In the Installation Results dialog box, confirm that BranchCache installed successfully, and then click Close.
Configuring a file server to use BranchCache
The BranchCache for Network Files role service of the File Services server role needs to be installed before you can enable BranchCache for any file shares. After you install the BranchCache for Network Files role service, use the Group Policy Management Console to enable BranchCache on the server. You can enable BranchCache for all shares on a file server or only on selected shares.
BranchCache for Network Files is a role service of the File Services role. Use the Add Roles Wizard of Server Manager to install the File Services role and the BranchCache for Network Files role service.

Server Branch Cache Configuration 2

Using Group Policy to configure BranchCache
To use Group Policy to configure BranchCache
Open the Group Policy Management Console. Click Start ->Administrative Tools -> Group Policy Management Console.
Select the domain in which you will apply the Group Policy object, or select Local Computer Policy.
Select New from the Action menu to create a new Group Policy object (GPO).
Choose a name for the new GPO and click OK.
Right-click the GPO just created and choose Edit.
Click Computer Configuration, point to Policies, Administrative Templates, Network, and then click Lanman Server.
Double-click Hash Publication for BranchCache.
Click Enabled.
Under Options, choose one of the following Hash publication actions:

• Allow hash publication for all file shares.
• Allow hash publication for file shares tagged with “BranchCache support.”
• Disallow hash publication on all file shares.

Server Branch Cache Configuration 3

Client Configuration
Once the Server 2008 machine is configured, you must enable it on the client machines.  It is disabled by default on client computers. Take the following steps to enable BranchCache on client computers:
Go to Start: Computer Management

Computer Management

Next Select Services and Applications

Computer Management - Services And Applications

Look For BranchCache and start it since it is a manual service; change it to automatic.

BranchCache-Services

You can review the Properties as well.

BranchCache Properties

Now the Branch Cache service is running, and it will work with the hosting Server to bring files to the local machine quickly and efficiently.

how to find ntp server in domain

I'm assuming that you're looking for the server used by the W32Time service to perform time sync on domain-member computers.
In a stock Active Directory deployment the only computer configured with a time server explicitly will be computer holding the PDC Emulator FSMO role in the forest root domain. All domain controllers in the forest root domain synchronize time with the PDC Emulator FSMO role-holder. All PDC Emulator FSMO role-holders in child domains synchronize their time with domain controllers in their parent domain (including, potentially, the PDF Emulator FSMO role-holder in the forest root domain). All domain member computers synchronize time with domain controller computers in their respective domains.
To determine if a domain member is configured for domain time sync, examine the REG_SZ value at HKLM\System\CurrentControlSet\Services\W32Time\Parameters\Type. If it is set to "Nt5DS" then the computer is synchronizing time with the Active Directory time hierarchy. If it's configured with the value "NTP" then the comptuer is synchronizing time with the NTP server specified in the NtpServer REG_SZ value in the same registry key.
The low-level details of the time synchronization protocol are available in this article: How Windows Time Service Works
Beware that not every domain controller (the KDC's, as James directs you in finding via DNS in his post) may be running a time service. In a stock AD deployment every domain controller will be, but some deployments may use virtualized domain controllers that have the W32Time service disabled (to facilitate hypervisor-based time synchronization) and, as such, you would probably do well to implement functionality as described by the "How Windows Time Service Works" article if you're developing a piece of software that needs to synchronize time in the same manner that a domain member computer would.

Re-sync to computer: w32tm /resync /nowait /computer:computername
Double check if its working: w32tm /monitor /domain:mydomain.com
See settings: w32tm /dumpreg /subkey:parameters
Then look at the Type:
NoSync: The client does not synchronize time.
NTP: The client synchronizes time from an external time source. Review the values in the NtpServer line in the output to see the name of the server or servers that the client uses for time synchronization.
NT5DS: The client is configured to use the domain hierarchy for its time synchronization.
AllSync: The client synchronizes time from any available time source, including domain hierarchy and external time sources.

Windows Server 2008 R2 and BranchCache

Driven by challenges of reducing the costs and complexity of Branch IT, organizations are seeking to centralize applications. However, as organizations centralize applications, the dependency on the availability and quality of the wide-area network (WAN) link increases. The increased utilization of the WAN link is a direct result of centralization, as is the degradation of application performance. Recent studies have shown that despite the reduction of costs associated with WAN links, WAN costs are still a major component of enterprises’ operational expenses.

BranchCache in the Windows 7 and Windows Server 2008 R2 operating systems can help increase network responsiveness of centralized applications when accessed from remote offices, giving users in those offices the experience of working on your local area network. BranchCache also helps reduce WAN utilization.

When BranchCache is enabled, a copy of data accessed from intranet Web and file servers is cached locally within the branch office. When another client on the same network requests the file, the client downloads it from the local cache without downloading the same content across the WAN.

BranchCache can operate in one of two modes:

• Distributed Cache. Using a peer-to-peer architecture, Windows 7 client computers cache copies of files and send them directly to other Windows 7 client computers, as needed. Improving performance is as easy as enabling BranchCache on your Windows 7 client and Windows Server 2008 R2-based computers. Distributed Cache is especially beneficial for branch offices that do not have a local server.
• Hosted Cache. Using a client/server architecture, Windows 7 client computers cache content to a computer on the local network running Windows Server 2008 R2, known as the Hosted Cache. Other clients who need the same content retrieve it directly from the Hosted Cache. The Hosted Cache computer can run the Server Core installation option of Windows Server 2008 R2 and can also host other applications.

The following diagram illustrates these two modes:

BranchCache can improve the performance of applications that use one of the following protocols:

• HTTP and HTTPS. The protocols used by Web browsers and many other applications, such as Internet Explorer or Windows Media, among others
• SMB (including signed SMB traffic). The protocol used for shared folders

BranchCache only retrieves data from a server when the client requests it. Because it is a passive cache, it will not increase WAN utilization. BranchCache only caches read requests and thus will not interfere with a user saving a file.

BranchCache improves the responsiveness of common network applications that access intranet servers across slow links. Because it does not require any infrastructure, you can improve the performance of remote networks simply by deploying Windows 7 to client computers, deploying Windows Server 2008 R2 to server computers, and enabling BranchCache.

BranchCache works seamlessly alongside network security technologies, including SSL, SMB Signing, and end-to-end IPsec. You can use BranchCache to reduce network bandwidth utilization and to improve application performance, even if the content is encrypted
