Yep, the SRV record thing is tricky because you can't create two srv records in the same domain for _sipinternatls. There are a few ways to deal with it, though.
I think the easiest way is to just manually configure your OCS clients for ocspool.company.com:5061. This will keep you from needing a separate SRV record.
However, the best long-term solution is this: If you are using an LCS access proxy, you can replace it with an OCS edge server. Then you can configure your internal SRV records to point to the outside interface of the Edge server (sip.company.com) on port 443. This way LCS clients all point to the Edge & then the edge distributes the request to the LCS front end. The OCS clients also point at the edge & it distributes the requests to the OCS front end. This is the way I have things woking in our environment and it has been working very well.
And I also agree with your strategy on the user migration, that's probably the best way to do it.

How to troubleshoot missing network connections icons in Windows Server 2003 and in Windows XP
This article describes general step-by-step methods and advanced troubleshooting methods that you can use to restore missing network and dial-up connections icons on a computer that runs Windows XP or Windows Server 2003. However, despite the missing icons, networking continues to function correctly. Because missing network icons can be a symptom of several issues, it is difficult to say what is causing your particular problem until you examine it a bit. We'll ask you some questions. Then, based on your answers, we'll determine which of these methods that you should try first.
This article provides self-help steps for a beginning to intermediate computer user.
The "Advanced troubleshooting" section is designed for the advanced computer user.
You may find it easier to follow the steps if you print this article first.

If this method did not work for you, you can try Method 4.
Back to the top
Method 4: Use the Dcomcnfg.exe utility to reset the "Default Impersonation Level" setting
This setting tells the computer how you want it to authenticate who can connect to a network. This method sounds more intimidating than what it really is. The DCOM Config utility has a point-and-click interface, and you just need to follow the steps, and it will do the "dirty" work for you.
Before you get started, you will need to make sure that you are logged on to the computer by using an administrator account. With an administrator account, you can make changes to your computer that you cannot make with any other account, such as a standard account. If you are using your own computer, chances are that you are logged on with an administrator account.
If you are unsure whether you have administrative user rights, follow these steps. Otherwise, go to step 1.
1. Open the Date and Time Properties dialog box.
1. Click Start, and then click Run.
2. In the Open box, type timedate.cpl, and then press ENTER.
2. Now determine whether you are logged on with an administrator account.
* If the Date and Time Properties dialog box opened after you performed step 1, you are logged on as a computer administrator. Close the Date and Time Properties dialog box, and then continue with this method.
* If you received the following message, you are not logged on as an administrator:
You do not have the proper privilege level to change the system time.
To continue with this task, you must first log off, and then log back on to Windows by using a computer administrator account. If you do not know how to log back on to Windows by using a computer administrator account, you might have to ask someone for help. If this computer is part of a network at work, you can ask the system administrator for help. However, if you have to perform this task on a home computer that is not part of a network, you must know the password for an administrator account on your computer.
Unfortunately, if you do not know the password for any administrator account on your computer, this content is unable to help you any further. You may want to contact support. See "Next steps" for information about how to contact support.
To run the Dcomcnfg.exe utility to rest the Default Impersonation Level setting, follow these steps:
1. Click Start, and then click Run.
2. Type dcomcnfg, and then click OK.
3. In Component Services, click Computers, right-click the computer whose machine-wide impersonation level that you want to modify (for example, My Computer), and then click Properties.
4. Click the Default Properties tab, and then click to select the Enable Distributed COM on this computer check box for this computer.
5. Click the down arrow in the Default Impersonation Level box, and then click any setting other than Anonymous, and then click OK.
The new machine-wide impersonation level is available the next time that you start a program. Programs that are currently running are not affected until you restart them.
Check to see whether your networking icons appear. If this method worked for you, you are finished with this article.
If this method did not work for you, you can try Method 5.

If you are still experiencing the missing icons problem, you can try the advanced methods. If you are not comfortable with advanced troubleshooting, you might want to contact Support. For information about how to contact support, see the "Next steps" section.
We recommend the following advanced troubleshooting methods for advanced users:
* Method 1: Verify that all Windows Protected Files in the System 32 folder are intact
* Method 2: Remove third-party network adapter management software
* Method 3: Use the Group Policy Results tool to see which Group Policy objects are applied
* Method 4: Reset the network connections
* Method 5: Verify that the registry keys are intact and correct
* Method 6: Check for nonpresent, ghosted, or hidden network adapters
* Method 7: Remove all the AutoDiscovery/AutoPurge (ADAP) information from the registry and reset the state of each performance library
Back to the top
Method 1: Verify that all Windows Protected Files in the System 32 folder are intact
System File Checker enables an administrator to scan all protected files to verify their versions. If System File Checker discovers that a protected file has been overwritten, it retrieves the correct version of the file from the cache folder (%Systemroot%\System32\Dllcache) or from the Windows installation source files, and then it replaces the incorrect file. System File Checker also checks and repopulates the cache folder. You must be logged on as an administrator or as a member of the Administrators group to run System File Checker.
To run System File Checker, open a command prompt, type sfc /purgecache, and then press ENTER. The Window File Checker starts.
For more information about how to use the Windows File Protection feature, review the following Microsoft Knowledge Base article:

If you are still experiencing the missing icons problem, you can try the advanced methods. If you are not comfortable with advanced troubleshooting, you might want to contact Support. For information about how to contact support, see the "Next steps" section.
We recommend the following advanced troubleshooting methods for advanced users:
* Method 1: Verify that all Windows Protected Files in the System 32 folder are intact
* Method 2: Remove third-party network adapter management software
* Method 3: Use the Group Policy Results tool to see which Group Policy objects are applied
* Method 4: Reset the network connections
* Method 5: Verify that the registry keys are intact and correct
* Method 6: Check for nonpresent, ghosted, or hidden network adapters
* Method 7: Remove all the AutoDiscovery/AutoPurge (ADAP) information from the registry and reset the state of each performance library
Back to the top
Method 1: Verify that all Windows Protected Files in the System 32 folder are intact
System File Checker enables an administrator to scan all protected files to verify their versions. If System File Checker discovers that a protected file has been overwritten, it retrieves the correct version of the file from the cache folder (%Systemroot%\System32\Dllcache) or from the Windows installation source files, and then it replaces the incorrect file. System File Checker also checks and repopulates the cache folder. You must be logged on as an administrator or as a member of the Administrators group to run System File Checker.
To run System File Checker, open a command prompt, type sfc /purgecache, and then press ENTER. The Window File Checker starts.
For more information about how to use the Windows File Protection feature, review the following Microsoft Knowledge Base article:
222193 (http://support.microsoft.com/kb/222193/ ) Description of the Windows File Protection feature

When you install Windows XP Service Pack 2 (SP2) or Service Pack 3 (SP3), you may receive an error message similar to one of the following:
Service Pack 3 setup error. Access is denied.
Service Pack 3 setup error. Service Pack installation did not complete
Or, the Svcpack.log file may contain the following error message:
DoRegistryUpdates failed
Back to the top
CAUSE

These errors can occur if permissions for one or more registry keys are restricted in a way that prevents the service pack from updating the keys. Registry keys can become restricted by certain programs that change the system access control lists (SACL) in the Registry so that administrator accounts cannot alter them. The service pack installer runs under an administrator account (User), and therefore cannot access restricted registry keys. If Windows XP Service Pack cannot update a registry key because it is restricted by another program, the service pack installation fails.
To determine whether an update to the registry has failed, go to the "More Information" section.

Use the following troubleshooting methods in the order in which they are presented to resolve the issue. These methods are intended for intermediate to advanced users.
Note You must be logged on to Windows with a user account that is a computer administrator to complete these methods. If this is your personal computer, you are likely already logged on with an administrator account. If this is a computer that is part of a network at work, you might have to ask the system administrator for help.

Method 1: Restart the computer, and then try to download and install Windows XP SP3 from the Microsoft Download Center
If a program is running with a locked file, restarting the computer may unlock the file. To try to unlock the file, exit all programs and restart the computer. Then try again to download and install the service pack.
If you originally tried to install Windows XP SP3 through Windows Update and it failed, download the full Windows XP SP3 download package from the Microsoft Download Center. After you download the service pack, try to install it. For more information about how to download Windows XP Service Pack 3, click the following article number to view the article in the Microsoft Knowledge Base:
322389 (http://support.microsoft.com/kb/322389/ ) How to obtain the latest Windows XP service pack
If this method resolved the error message and if you successfully installed Windows XP SP3, you are finished.

If this method did not resolve the issue, go to method 2.
Back to the top
Method 2: Restart the computer, and then close or disable any antivirus or antispyware program that may be running
Warning This workaround may make a computer or a network more vulnerable to attack by malicious users or by malicious software such as viruses. We do not recommend this workaround but are providing this information so that you can implement this workaround at your own discretion. Use this workaround at your own risk.
You can reduce the risk of attack by malicious users or malicious software by not visiting other Web sites or downloading files while your antivirus and antispyware program is closed or disabled.
One of the most common causes of installation failure is when a third-party program, such as an antivirus program, holds a file open or locks a file that the service-pack installer needs. To prevent this issue, follow these steps before you install Windows XP SP3:
1. Exit all programs, and then restart the computer.
2. After you restart the computer, close or disable any antivirus or antispyware programs that may be running.
Note You can disable the programs from the notification area. To do this, right-click the third-party program icon, and then click an option to close or to disable the application. If this option is not available, see the program documentation, or contact the program's manufacturer for instructions.
3. After you close the antivirus program or the antispyware program, install Windows XP SP3 from the full download package that you downloaded in method 1.
4. After Windows XP SP3 installation is complete, restart the antivirus program or the antispyware program that you disabled in step 2.
If this method resolved the error message and if you successfully installed Windows XP SP3, you are finished.
If this method did not resolve the issue, and if you are comfortable trying advanced troubleshooting steps, go to the "Advanced troubleshooting” section. If you are not comfortable with advanced troubleshooting steps, go to the "Next Steps” section.

Generic BackDoor!by virus problem
Recently I faced lot of problem with Generic BackDoor!by . this virus is changing net man.dll file in registry to tabcteng.dll . first check for virus with Mcafee and then follow the below procedure. After changing the name in registry restart the system.
Check the registry key:
HKLM\System\CurrentControlSet\Services\%ServiceName%\Parameters
2. Check the associated DLL file name value for ServiceDLL.
3. Physically check the location mentioned in the key ServiceDLL and make sure that the file is there.
4. If you do not find the file at the location mentioned in the key HKLM\System\CurrentControlSet\Services\%ServiceName%\Parameters\serviceDLL then copy the file from a working Server with the same OS and Service Pack Level.
5. Now try to start the service and the service should now start otherwise restart the system.
unable to open run from start menu
Look at these two reigistry keys, if they both exist. Look for a Value Name
called NoRun. If NoRun exists, the Value Data should be set to 0. If NoRun
does not exist it's the same as being set to 0.
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\
CurrentVersion\Policies\Explorer
and
HKEY_CURRENT_USER\Software\Microsoft\Windows\
CurrentVersion\Policies\Explorer
Value Name: NoRun
Data Type: REG_DWORD
Value Data: 0 or 1
0 (or not in the registry) = The policy is disabled or not configured. The
Run command appears.
1 = The policy is enabled. The Run command is removed.
called NoRun. If NoRun exists, the Value Data should be set to 0. If NoRun
does not exist it's the same as being set to 0.
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\
CurrentVersion\Policies\Explorer
and
HKEY_CURRENT_USER\Software\Microsoft\Windows\
CurrentVersion\Policies\Explorer
Value Name: NoRun
Data Type: REG_DWORD
Value Data: 0 or 1
0 (or not in the registry) = The policy is disabled or not configured. The
Run command appears.
1 = The policy is enabled. The Run command is removed.
Description
Removes the Run command from the Start menu and removes the New Task (Run)
command from Task Manager. Also, users with extended keyboards can no longer
display the Run dialog box by pressing the Application key (the key with the
Windows logo) + R.
This entry stores the setting of the Remove Run menu from Start Menu Group
Policy. Group Policy adds this entry to the registry with a value of 1 when
you enable the policy. If you disable the policy or set it to Not
configured, Group Policy deletes this entry from the registry, and the
system behaves as though the value is 0.
This entry affects the specified interfaces only. It does not prevents users
from using other methods to run programs.
Change method
To change the value of this entry, use Group Policy. This entry corresponds
to the Remove Run menu from Start Menu Group Policy (User
Configuration\AdministrativeTemplates\Start Menu & Taskbar).
