I upgraded to a new (much faster) ISP and the new router has an IP range that is different from the prior one so devices on the network could not connect. I have updated all devices on the network, including one PC that I use as a Media Center library server for a client system. The client PC works fine on the network, connecting to my NAS, the internet, etc., but Media Center cannot find the server on the other computer to add its library or sync the client local library with the server library. It still tries to connect to the old IP. I tried adding a new library after I changed the access key on the server but it still tried the old IP. I uninstalled Media Center and reinstalled on the client but had the same result. There is clearly stored/cached data that points to the old IP address. Please recommend ideas for what I can do to get the Media Center client to see and connect to the server. The server PC sees the client just fine and I did a Sync with the client local library from the server and it worked fine. I cannot see any setup differences between the two computers and it all worked fine before this change. Both PCs are fully updated Win 10 machines. Both Media Centers are 27.0.79 (64 bit).
