(http://support.microsoft.com/kb/256986/ )Description of the Microsoft Windows registry
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.
