问题
Installed the tfs 2017 (update 1) build agent on a machine and ran config.cmd to connect it to a TFS server. That server had to be reconfigured and the original url that the build agent was pointing to is no longer valid. All I want to do is reconfigure the build agent to connect using the new url. When I run config.cmd again, it says that I must first call 'config.cmd remove' but when I run that, it fails because it is trying to reach out to the original url to remove itself from the agent pool.
How can I force it to uninstall so that I can configure a new one? I have even deleted the whole agent directory, re-extracted from zip, and tried again but it's detecting that it's configured from somewhere else.
回答1:
Delete/rename the .agent file and then try to unconfigure:
C:\TfsData\jessehouwing>config.cmd remove
Removing service
