Changing the ports that several of our servers run on. Tried to use the "Update Scanning Parameters" feature to do this, but it kept throwing back the error "THIS SERVER CANNOT BE SCANNED".

Do I need to delete the servers from GT entirely, and re-enter them? That would suck as it would loose all history.

Is there any less intrusive way to accomplish this?

Hello weaselslair,

If you are simply changing the query port, you can use that update scanning parameters dialog to change the query port. If you would like to change the join port, you'll need to re-add the server and start from scratch.
