Do you know the IP address of your server now?
Can you ping your server from your client PC?
If you can ping your server then see if can you get to your server's software share using the IP address..
\\192.168.xxx.xxx\software
Try and install the latest version of the connector software available there?
Or from a browser try and reach it this way:
http://[name of your home server]:55000
Alternatively can you use Remote Desktop to see if there server is up and running, might be something in the event log...
