TFS 2013: HTTP code 503: Service Unavailable

Question

All of a sudden, our TFS server down. When I checked in IIS, http://localhost:8080/tfs is giving 503 service error.

Below application pools are getting stopped automatically, even though I manually made them start in IIS manager. Microsoft Team Foundation Server Application Pool, Microsoft Team Foundation Server Proxy Application Pool

Please guide me to solve this issue

2. Again I changed from workgroup to domain and restarted the machine.
3. Goto IIS manager->Application Pools->Right click on Microsoft Team Foundation Server Application Pool->Advance Settings
4. Under Process Model section, Set the identity again with my domain credentials
5. reset IIS by running IISReset command as admin

Thank you for your replies.

When TFS Build reports the 503 error it can just be a temporary issue. This can happen if you are attempting to access the build server just after first configuring it—or, in your case, just after the TFS server has gone down and has been restarted—and the relevant services are not yet fully available.

Resolution in this case is simply a matter of waiting, and retrying in 5 or 10 minutes or so.
