Failed to register this test agent with the test controller. Possible reasons could be you do not have the right permissions to connect to the test controller {0}, the log on account does not exist on the test controller machine, or a firewall is blocking the connection.
To fix this problem, verify that you are a local administrator on the test controller machine, that the log on account {1} exists on the test controller machine, and that the Windows Firewall Settings on the test controller machine has "File and Printer Sharing" exception.
