We are trying to setup a build agent and every time we start it the log shows the following messages:

Has anyone seen anything like this before? We've looked at the server logs and aren't seeing anything on them to indicate what could be wrong.

I ran into the same issue. Both the build agent and the server are installed on Windows Server 2012.

I stopped the build agent service and deleted the logs from BuildAgent\logs and restarted the build agent service so I could see a fresh log.

upgrade.log showed me that the build agent received a call from the teamcity server to upgrade. The log also showed the following:

"Please check TeamCity build agent service user have enough permissions to stop and start the service."

Using the Local Security Policy, I granted the build agent service user "logon as a service" rights but this is not sufficient to start and stop a service. By default, only members of the Administrators group can start, stop, pause, resume or restart a service. After I added the build agent service user to the Administrator group and restarted the build agent service, the upgrade finished successfully and the agent connected again.
