SYMPTOMS

Consider the following scenario. During the initial installation of Microsoft Windows Server 2003 Compute Cluster Edition, you set the number of concurrent connections to a number other than the default setting. You set this number on the Licensing Modes screen. Then, you run the Sysprep tool (Sysprep.exe) on the computer to prepare the image for deployment to multiple computers. Finally, you run Mini-Setup on one of the deployed Windows Server 2003 Compute Cluster Edition-based computers.

In this scenario, the number of concurrent connections is reset to 10 on the deployed Windows Server 2003 Compute Cluster Edition-based computer. You can use the Licensing item in Control Panel to verify this.

Note In Microsoft Windows Server 2003 SP1 x64 Edition, the Licensing Modes screen is displayed during Mini-Setup. Because you can set the number of concurrent connections on the Licensing Modes screen, this problem does not occur in Windows Server 2003 SP1 x64 Edition.

WORKAROUND

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk. To work around this problem, edit the ConcurrentLimit registry value in the following registry subkey to change the number of concurrent connections that are allowed by Windows Server 2003 Compute Cluster Edition:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LicenseInfo\FilePrint
To edit this registry value, follow these steps:
  1. Click Start, click Run, type regedit in the Open box, and then click OK.
  2. Locate and then click the following registry subkey:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LicenseInfo\FilePrint
  3. Right-click the ConcurrentLimit entry, and then click Modify.
  4. In the Value data box, type a number that is sufficiently large to handle the maximum number of concurrent connections that the Windows Compute Cluster Server 2003-based computer might experience. Then, click OK. For example, type 999.
  5. Exit Registry Editor, and then restart the computer.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
