Offline files - Server is available, but Windows thinks its offlin



I have been using offline files for a while, but I have noticed that over the
past few months when I get back on the network Windows doesn't recognize the
server as online. I can ping the server and get replies, and I can get to it
through the IP address, but the NetBIOS name takes me to the offline version.
Any ideas why this might be and how can I get Windows to recognize the

I have tried flushing dns cache (ipconfig /flushdns) and clearing &
reloading the NetBIOS cache (nbtstat -RR), but that didn't resolve the issue.

Any help would be greatly appreciated, thanks!
