TeamCity build agent disconnected

Question

I installed a build agent on Windows 7 and always have the agent show up as "disconnected". The log teamcity-agent.txt shows below information

 If this is the first time this agent registered on the server make sure it is     authorized by administrator in the server web UI.

Here is a very comprehensive blog on re-connecting disconnected agents

http://michaelbarnesjr.wordpress.com/2012/10/18/teamcity-build-agent-disconnected/

Here are the steps (copied from the above link)

If an agent becomes disconnected for whatever reason, you can follow these steps to re-connect it:

• ssh to the server that the disconnected agent is on.
• go to the build agent’s bin directory (i.e. /opt/teamcity/buildagent/buildagent01/bin/)
• su to the user that the agent runs as (i.e. appBuilder)
• run agent.sh start

That will start the agent, and after a few seconds or so, the next time you go to TeamCity, it will be connected.

If Team City is running on a windows server, you can connect to that server, go to Services and restart the build agent that has become disconnected.
