The remote desktop was drawn up on my PC as a frame and then everything stopped. After googling and asking on a microsoft NG I got the advice to change the networking parameter: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NdisWan\Parameters\Protocols\0 value ProtocolMTU Advice was that the value should be lowered until working. I now have it set to 1300 (don't remember what it was before) and then the remote desktop started to work properly again. Is this the same thing, then I would like to know where to change it. The above fix was connected to the VPN tunnel traffic. Any hints? HTH /Bo (Bo Berglund, developer in Sweden)
