How to remove the Compute Cluster Pack from the head node of a Windows Compute Cluster Server 2003-based cluster (923736)

MORE INFORMATION

Each Windows Compute Cluster Server 2003-based cluster must have a head node. The head node provides management services for the compute cluster. Management services include the following:

• Job scheduling
• Job and resource management
• Remote Installation Services (RIS)
• Remote command environment

The head node may also serve as a network address translation (NAT) gateway between the cluster private network, if one exists, and the public network. The NAT gateway is a part of the Internet Connection Sharing feature.

Before you install the CCP on the Windows Compute Cluster Server 2003 head node, you must install some required software. Required software includes the following:

• Microsoft SQL Server 2000 Desktop Engine (MSDE 2000a)
• The Microsoft .NET Framework 2.0
• Microsoft Management Console (MMC) 3.0
• RIS hotfix 907639 (This hotfix is required if you use the Automated Deployment method to deploy compute nodes.)
• Internet Connection Sharing hotfix 897616 (This hotfix is required if Internet Connection Sharing is enabled on the head node.)

For more information about the software requirements, visit the following Microsoft Web site:To remove the CCP from the Windows Compute Cluster Server 2003 head node, follow these steps:

1. Click Start, click Run, type appwiz.cpl, and then click OK.
2. In the Currently installed programs list, click Microsoft Compute Cluster Pack, and then click Remove.
3. Follow the instructions to remove the CCP.

If you remove MSDE before you remove the CCP, the removal process is unsuccessful. At this point, you can use one of the following methods:

  1. Click Start, click Run, type cmd, and then click OK.
  2. At the command prompt, switch to the MSDE2000a folder on the CCP distribution media.
  3. Type setup.exe SAPWD="strong_password" INSTANCENAME="COMPUTECLUSTER", and then press ENTER.
     
     Note The strong_password placeholder represents the System Administrator (SA) password.
  4. Type exit, and then press ENTER.
