Hello!

Could someone help me resolving the TF31004 error?

TF31004: Team Foundation encountered an unexpected error while connecting to Team Foundation Server <server_name>. Wait a few minutes and try again. If the problem persists, contact your Team Foundation Server administrator.

I get this message when connecting to TFS from all client machines. TFS is up and running and I don't have any issue working in VS2005 on the server itself.

Thanks!

To help us better understand your issue, can you please tell me if you were ever able to connect to the server via the clients? If so, were there any server configuration changes or reboots around the time this started happening?

It sounds like the clients cannot connect to the AT. Can you browse to :

http://<MachineName>:8080/VersionControl/Repository.asmx

I rebooted the tfs server and I was able to reconnect to the server. But, I still don't know what caused this error.

Since this was a dev box, I had no issues rebooting. How do I come around this issue if it were a prod server? Do I have to kick everyone out accessing the server?

I'm glad to hear you're up and running now, though I'd still like to try to understand the root cause of your problem.

Were you ever able to connect to the server from external clients before you started seeing the connection problem? Are there any entries in the server event logs from around the time when the problem started? Were any Windows Updates installed on the server around the time the problem started happening?

I was not able to connect to any of the clients prior to the reboot. There were no windows updates around that time. But, I found the following Application event log errors:

Windows cannot query for the list of Group Policy objects. Check the event log for possible messages previously logged by the policy engine that describes the reason for this.
Windows cannot find the machine account, The specified target is unknown or unreachable .

Thanks.

Were there any errors in the event log of the application tier or the client that correspond to the times when you experienced the problem?
