Cannot Authorize Build Agent

I'm having problems authorizing a second agent in TC 5.0.3.

TC is installed on a windows 2008 server and has a working build agent running under a domain account

I have a second build agent located on a windows 2003 server box running under the same domain account.

The build agent on this server is connecting but showing twice as both connected and disconnected in the build agent (unauthorized) view


When I go to authorize the connected agent, the logs indicate that it does so, then immediately unauthorizes it again.

Is there any particular log file or setting I should be using to get more detail on why this is happening?

Hello Scott,

Could you please provide all agent and server log(s)?  If it contains sensitive data you can send it to teamcity-feedback[at]
Could you please also check that there is only one process started by the agent?

Kind regards,

Hi Marina

This is the same issue with attached log files (sorry for duplicate thread, just found this one):

I confirm there is only one process started.
