TFS build agent, same port as team server? -

The foundation of my team is set up to use port 8080, when I am creating a new build agent Port 9191 is the default.

Which should I use?

When I try and get an error in running my build, it says that the build agent was unreachable.

I created a share on my drive c: \ tfsbuilds, and I added the TFSService account and gave it full power.

I am using \ computername \ tfsbuilds as my path to the Build folder.

What else can be wrong?

Error Message

Create Team Foundation Computer on TFSBUILDS. MyServer1.local (Port 9191) is not responding. (Detailed message: Unable to connect to remote server)

Is the build service started? This is probably the most common problem because the service must start first. And yes, 9191 is the default port for the build agents. Can you also check your firewall?
