My testing and workflows are failing.

The workflow fails for this reason. enter image description here

But I have the TFS build service on the environment and the agent has the green light beside it.

The testing fails for this reason. enter image description here

I have the test controller on the TFS machine and the test agent on the environment, I don't have the agent registered with the controller as its in a MTM environment.

Any help would be appreciated. Thank you.

The machine is not ready to run tests because of the following error: Unable to connect to the controller on 'TFSSERVER.cct.local:6901.' Reason: No such host is known.

So, it's trying to connect to TFSSERVER.cct.local on port 6901, and can't because No such host is known. Sounds like a DNS issue. Make sure that there's an entry for TFSSERVER.cct.local in your DNS, and it's on a network or subnet you can access. (Assuming that's actually the machine you want to connect to.)

I can ping the servers from each other, and have registered the agent with the controller manually, but I'm still getting the error. I'm not network savy, so I'm not sure what the story is with the DNS, but the two machines are on the same domain. – ELSheepO Aug 17 '12 at 12:09
@ELSheepO, did you ping the domain or the IP? If you used "ping tfsserver.cct.local" and it was successful (and works from either machine to the other), it's probably not a DNS problem. – Russ Amos Aug 17 '12 at 12:36
@RussAmos Ya I pinged tfsserver.cct.local, was successfull. – ELSheepO Aug 17 '12 at 12:48
@ELSheepO, check your firewall settings. According to this msdn forum post, you need both 6901 and 445 open for TCP into both machines. – Russ Amos Aug 17 '12 at 12:54
