You may receive an error message when you try to run the Exchange Management Pack Configuration Wizard in a Microsoft Exchange Server 2003 clustered environment

When you run the Exchange Management Pack Configuration Wizard, and you try to configure Microsoft Exchange Server 2003 in a clustered environment, you may receive an error message that is similar to the following: Note There may be multiple error messages of a similar kind. Each error message indicates a unique computer.

This issue occurs when some of the nodes in the cluster are not running Microsoft Exchange Server. Therefore, they do not have the Exchange Server program files installed locally. The Configuration Wizard returns an error for each node.

To resolve this issue, follow these steps:

1. Copy the Exchange Management Pack key publisher executable file (EMPKP.exe) from an Exchange Server to the nodes where Exchange Server is not installed.
   
   Note You can copy the EMPKP.exe file to any appropriate folder. The EMPKP.exe file is located in the Drive_Letter:\exchsvr\bin folder.
2. On the nodes where Exchange Server is not installed, run the EMPKP.exe file as follows:
   
   EMPKP /regsvr
3. Use the Administrator Console in Microsoft Operations Manager (MOM) to create a temporary computer group that only includes the nodes where Exchange Server is not installed.
   1. Click Start, point to Programs, point to Microsoft Operations Manager 2005, click Administrator Console.
   2. Expand Microsoft Operations Manager (Your_Computer_Name), expand Management Packs, and then click Computer Groups.
   3. Right-click Computer Groups, and then click Create Computer Group.
   4. Click Next.
   5. Type Temp_Computer_Group in the Name box, and then click Next two times.
   6. Click Add.
   7. In the Add Computer dialog box, click to select Computer_Name where Computer_Name is the name of a cluster node where Exchange Server is not installed. Select all the cluster nodes where Exchange Server is not installed.
   8. After you have selected all the required computers, click OK.
   9. Click Next six times. In the respective dialog boxes, accept the default values that are already selected.
   10. Click Finish.
4. Create a temporary rule group, and associate it together with the computer group that you created in step 3j.
   1. In the MOM 2005 Administrator Console, right-click Rule Groups, and then click Create Rule Group.
   2. Type Temp_Rule_Group in the Name box, and then click Next.
   3. Click Finish.
   4. Click Yes, and then click Add.
   5. Click the Temp_Computer_Group that you created in step 4d, and then click OK two times.
5. Copy the following rule to the temporary rule group:
   Microsoft Exchange Server\Exchange Management Pack Configuration Data\Publish Exchange Management Pack Configuration Data.

   4. Quit the MOM 2005 Administrator Console.
7. In the MOM 2005 Administrator Operator Console, monitor for the �Exchange MOM 9986� event on the nodes where Exchange Server is not installed.
   1. Click Start, point to Programs, point to Microsoft Operations Manager 2005, and then click Operator Console.
   2. In the navigation pane, click Events.
   3. In the navigation pane, expand All Events, and then click Events.
   4. In the results pane, click the Event Number column heading to sort the events by event numbers.
   5. Wait until you see Event Number 9986 for each node where Exchange Server is not installed.
   6. Quit the MOM 2005 Administrator Console.
8. Delete the temporary computer group and the rule group.
   1. Click Start, point to Programs, point to Microsoft Operations Manager 2005, and then click Administrator Console.
   2. Expand Microsoft Operations Manager (Your_Computer_Name), expand Management Packs, and then click Computer Groups.
   3. Right-click Temp_Computer_Group, and then click Delete Computer Group.
   4. Click OK, and then click Yes.
   5. Expand Rule Groups.
   6. Right-click Temp_Rule_Group, and then click Delete.
   7. Click OK.
   8. Quit the MOM 2005 Administrator Console.
9. On the nodes where Exchange Server is not installed, run the following command:
   
   EMPKP /unregserver
10. Delete the EMPKP.exe file that you copied from the nodes where Exchange is not installed.
11. Run the Exchange Management Pack Configuration Wizard again, and then select the Exchange Server computer that you want to configure.

Symptoms information:

If there is a six-node cluster with Exchange Server running on four of the nodes, the following configuration may appear:

Node1 Exchange (active)
Node2 Exchange (active)
Node3 Exchange (active)
Node4 Exchange (passive)
Node5 SQL (active)
Node6 SQL (passive)

In this scenario, the Configuration Wizard will return the following errors:

Resolution information:

When you perform the steps that are described in the "Resolution" section, the following events occur:

• The correct public and private key pair is created on the nodes where Exchange Server is not installed.
• The encrypted registry subkey content and the crypto container are protected with Access Control Lists.
