The Network BIOS Session Limit Exceeded

Hi All,
I'm hoping someone can help me with a problem I'm having.

About 2 months ago the hard drive on our web server started to play up so I
decided to do a new install of windows 2003 server to the new hard drive, and
just publish the website to the new server. Everything went fine until about
4 weeks ago, the web site started losing access to the file server. The event
logs says the network BIOS session limit exceeded and all the help I can find
says this is a known problem when you use IIS on windows server 2000 and use
mapped drives. We are using windows 2003 server and we use the full UNC path.

Here is the information on the servers:
Our Website is running windows 2003 standard server with all current patches
in place.

The file server is a windows 2000 server with all current patches in place.

Here is the error log.

There are reg keys that you need to set. It is in this doc

Also you might want to check your limit on your remote device

Thanks Phil,

I'll give it a try, and hopefully this will solve the problem.

Thanks,
