I have encountered the same problem as someone n|0s who described it about year ago as : "Ok heres my setup. I've got 2 networks, one at a main office and one at a small remote office. Both offices have DSL connections, the second office VPN's into the main office, which is running a NT 4.0 server (with SP6a). The second office has a peer-to-peer win98 network. One computer access the DSL line using RASPPPoE and shares the connection with the rest of the network using WinRoute Pro. Ok, now on to the problem. I can establish a VPN connection, map drives to the server at the main office, and access data on the mapped drives with no problem, but after the drives have been mapped for a few minutes they become in accessible. If you try to access them you get an error stating that the network path cannot be found. The VPN connection and the DSL are both still up and functioning. Pings to the server also go through fine, so i dunno wtf if up. Any help would be greatly appretiated." I tried contact him but his mailbox is unaivailable Please help me to solve this problem Any information would be valueable Thanks in advance

You need to setup a WIN's server on the main network and have all the network devices point to it.
