Vpn Error message…new to me.

I recently set up a VPN tunnel using a Watchguard SOHO for remote access to a small WIN2000 network with a DSL connection.

I can connect fine but when I, for instance map a drive and then attempt to use it I get an error message that includes thewords “Network name is no longer available”

Double checked my LMHOSTS file and all is well.

When I research this error at the MS site I find nothing. Any suggestions?

Thanks!
