did your computers ip adress change? did you assign a static ip adress for it? because if you didnt chances are your router reassigned your computer a new internal ip.

 

I've been having problems with SMB. Managed it fine with my XP setup, same machine but Windows 7. Just won't work.

The joke is, I managed to display the file list once, came out of it to just double check what settings I'd put in to remember. Once I went back into it, same again, can't be found.

I gave up in the end after messing with permissions, shares, windows firewall, router firewall, everything. I'm buggered if I know what it is. Keep us posted if you managed to solve it though.
