Question

Office Communicator Certificate Error

Asked by: epaschal

have just installed Office Communications Server 2007 R2 on Server 2008.

I created a self signed certification on the server running OCS. At this point web access works just fine. However when I try to connect using Office Communicator , the following event is registered and the connection fails.

The server I generated the certificate on, and the PC I am connecting from, are all part of the same domain. Not sure what to do at this point, and my certificate experience is limited. Given the number of users, I can't manually install a certificate at each workstation.

Error event:
Event Type: Error
Event Source: Communicator
Event Category: None
Event ID: 5
Date:  10/18/2009
Time:  1:45:32 PM
User:  N/A
Computer: 1175PC
Description:
Communicator could not connect securely to server ocsserver.companydomain.local because the certificate presented by the server was not trusted due to validation error 0x80090325.  The issuing certificate authority (CA) for the server's certificate may not be locally trusted by the client, the certificate may be revoked, or the certificate may have expired.

I suppose I should mention, if it helps, that the AD controller is a Server 2003 machine.

On your AD Controller or on a separate member server and not the OCS server install the Windows Certificate Authority role from Add/Remove WIndows Programs.  I recommend that the Windows OS be enterprise version as an enterprise certificate authority automatically support client and server root certficate autoenrollment setup.

You'll also need IIS on the certificate authority and select Web Enrollment also.

Once you have the certificate authority up and running you can then use the OCS Certificate Wizard to request and assign your OCS Pool certificate and then also update IIS on the OCS box to use that new certificate for the Pool.

For more information on deploying certificates download the document for OCS 207 R2 Deploying Certificates from the OCS documentation download link http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=e9f86f96-aa09-4dca-9088-f64b4f01c703
