Issues
• Uninstalling Windows Server 2003 Service Pack 2 causes links to the Access Suite Console/Access Management Console to break.
Windows Server 2003 Service Pack 2 upgrades the Microsoft Management Console (MMC) to version 3.0. MMC 2.0 console files (.msc) with user preferences that are opened by MMC 3.0 are updated to the MMC 3.0 format. If MMC 3.0 is uninstalled, MMC 2.0 cannot open the console files that have these updated user preferences.
Workaround
See Microsoft Knowledge Base article 907265.

- Citrix recommends that you install Windows Server 2003 Service Pack 2 on a server running Presentation Server 4.5 64-bit Edition to resolve the following potential issues:
The following error messages might appear in the Event Log or while running discovery using the Access Management Console on servers running Presentation Server 4.5 64-bit Edition for Windows Server 2003 with Service Pack 1:
In the Event Log: "The COM+ System Application service failed to start due to the following error: The service did not respond to the start or control request in a timely fashion."
In the Access Management Console: "Errors occurred when using <server name> in the discovery process. Citrix MFCOM Service did not respond as expected. Make sure that your user account is a member of this computer’s Distributed COM Users group if you are connecting to a remote server. Check the version of Citrix Presentation Server on the computer and ensure that a compatible version of Citrix MFCOM Service is installed and running."
This issue might be caused by an intermittent flaw in Microsoft’s COM+ subsystems that prevents the proper installation of Presentation Server components. For more information, see CTX112182 – The Access Management Console Fails During the Discovery Process After Installing the 64-bit Edition of Presentation Server 4.5.
