Hi,
assuming the server has moved with you, we need definitivaly more details.
What kind of error message do you get?
I would see two potential reasons: No proper network configuration in your new home (i.e. server got a fixed IP address before, the client has DHCP enabled and gets now an APIPA address) or an hardware issue, server having damaged disk or disconnected internal
cables after transport.
Is the network connected via switch? Which IP addresses do the machines get?
At least you should be able to ping the server by it's name from the client for a first test.
Can you logon locally or (if it is a system without video card) via Remote Desktop? If so, are there any errors in the event log?
Best greetings from Germany
