TFS2010 Lab: Build agent fails to connect using HTTPS and Machine name

Symptoms

Build agent fails to connect to the Application Tier using HTTPS and machine name not DNS name.

↑ Back to the top

Cause

Occurs with Notification URL matching Lab URL but the machine name is different. The Agent connects to App Tier using the machine name not the Notification URL or the Lab URL when there is a DNS record (CName) for the machine name.
In this case, it picked up the name from a DNS record (CNAME) for the machine.

Resolution

Workarounds are either make Lab URL the machine name (allowing non-SSL connections), allow SSL connections using the machine name as well or do not have a CName record in DNS for the machine name.

More Information

Ordinarily, this is not a problem, but because the machine was set for SSL, the incoming connection from the Build Agent to the Application Tier was using https:\\MachineName and did not match the certificate name. Therefore, the connection was rejected.
