APPLIES TO


 * Microsoft Exchange Server 5.5 Service Pack 2

This article was previously published under Q231751





SYMPTOMS
After applying Service Pack 2 (SP2) for Microsoft Exchange Server 5.5, you cannot renew certificates from the Key Management Server. Clients receive e-mail saying the request failed, and error 5006 is received on the server.



CAUSE
A missed case caused the Key Management Server component to return an error code.



RESOLUTION
To resolve this problem, obtain the latest service pack for Exchange Server version 5.5. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

191014 XGEN: How to Obtain the Latest Exchange Server 5.5 Service Pack

The English version of this fix should have the following file attributes or later:

Component: KM Server



STATUS
Microsoft has confirmed that this is a problem in Microsoft Exchange Server version 5.5 Service Pack 2. This problem was first corrected in Exchange Server 5.5 Service Pack 3.



MORE INFORMATION
Even after the fix is applied, you will need to recover these accounts because accounts that fail to renew generate a new signing key and send that to the server. Then, when they fail to renew, they are never given back that signing key. So now the client still has the first signing key (1) and the server has the new signing key (2). After the fix is applied and the account tries to renew again, it signs its request with signing key 1, but the server is expecting signing key 2. The account must be recovered to get the same signing key to the client and the server. After the recovery, the client and server are in sync, and any renewal or recovery works fine.
