Timeslips Migration Running Slow after Old Server Disconnected

We recently moved Timeslips 2017 to a new server and everything was running fine. The old server was handling DS for awhile, but that has all been moved to the new server. However, I have noticed that if I turn off the old server opening a new slip in Timeslips takes a very long time. As soon as I boot back up the old server Timeslips runs normally.

I've migrated the database and the admin to the new server. As far as I know nothing is still pointing to the old server. In fact, Timeslips does function without the old server just terribly slow.

I'm wondering if I'm missing some link that is still going to the old server. I did noticed that WINS is installed on the old server, but not the new. However, I'm not sure if Timeslips utilizes that feature.

Any help would be greatly appreciated.

Thank you
