Have an installation running TC 7.04 on a Windows 2008 Server. TC and 3 build agents run on the same server.
Everything has been running fine for quite a while until today I had a build hang that would not stop. I had to forceably stop the agent's windows service. Upon restart it would not connect. I then tried restarting all agents, as well as, the TC Web server. After that none of the agents would connect so I then restarted the OS, which in the past has cleared up things like this.
After rebooting and having Teamcity and the Agents start sucessfully, they still will not connect. TC recognizes them but the status is Disconnected. I've looked through the TC server and agent logs hoping to find some sort of error but don't really see anything that would indicate a problem.
