INTRODUCTION

This article describes how to manually remove Microsoft Antigen 9.0 together with Microsoft Antigen 9.0 Service Pack 1 (SP1) from a server cluster.

To do this, you must perform the following actions:
  • Remove Antigen 9.0 from each cluster node
  • Modify the registry to verify that all Antigen-related components have been removed correctly
Note You do not have to stop the Antigen-related services to remove Antigen 9.0.

The information in this article applies to the following programs:
  • Microsoft Antigen 9.0 for Exchange together with Antigen 9.0 SP1
  • Microsoft Antigen 9.0 for SMTP Gateways together with Antigen 9.0 SP1
  • Microsoft Advanced Spam Manager 9.0 together with Antigen 9.0 SP1

MORE INFORMATION

To remove Antigen 9.0 together with Antigen 9.0 SP1 from a server cluster, follow these steps.

Step 1: Remove Antigen 9.0 from each cluster node

To do this, follow these steps:
  1. On the active cluster node, click Add or Remove Programs in Control Panel.
  2. In the list of installed programs, click the Antigen 9.0 program that you want to remove. For example, click Microsoft Antigen 9.0 for Exchange.
  3. Click Uninstall, and then click OK.

    Note When you remove Antigen 9.0, the Remove Programs tool performs the following actions:
    • It stops Internet Information Services (IIS).
    • It takes the Microsoft Exchange Server virtual server offline on the active cluster node.
  4. After Antigen 9.0 has been removed from the active cluster node, remove Antigen 9.0 from any other active cluster nodes in the server cluster.
  5. After Antigen 9.0 has been removed from all the active cluster nodes, remove Antigen 9.0 from each passive cluster node.
  6. Manually verify that all the Antigen-related folders have been removed from the local hard disk drives and from the shared storage location.

    Important The program uninstaller may prompt you to restart the computer. However, do not restart any computer in the cluster until Antigen 9.0 has been removed from all the cluster nodes. Additionally, do not manually move any Exchange virtual server to another cluster node until Antigen 9.0 has been removed from all the nodes in the server cluster.

    If an active node is restarted before Antigen 9.0 has been removed, the Exchange virtual server that is hosted by that node may fail over to a passive cluster node before Antigen 9.0 can be removed from the passive cluster node.

Step 2: Modify the registry

To do this, follow these steps.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

  1. On the active cluster node, click Start, click Run, type regedit, and then click OK.
  2. On the Edit menu, click Find, type SMTP Virtual Server, and then click OK.
  3. Expand the SMTP Virtual Server registry subkey, and then click the Regsync registry subkey.
  4. In the details pane, delete all the registry entries that refer to the Antigen 9.0 registry key.

    If no entries remain in the Regsync registry subkey after you delete the Antigen-related registry entries, delete the Regsync subkey.
  5. On the Edit menu, click Find, type Exchange Information Store, and then click OK.
  6. Expand the Exchange Information Store registry subkey, and then click the Regsync registry subkey.
  7. In the details pane, delete all the registry entries that refer to the Antigen 9.0 registry key.

    If no entries remain in the Regsync registry subkey after you delete the Antigen-related registry entries, delete the Regsync subkey.
  8. Follow steps 1 through 7 for each cluster node that may host an Exchange virtual server.
  9. Take each Exchange virtual server offline, if it is not already offline.
  10. Bring each Exchange virtual server online.
