RRAS Connections dropping

hi all


I have win 2003 server which is configured to use RRAS so that vpn clients
can dial-in. It is also a Terminal server. A remote office has 8 users who
connect in and use a terminal session to access all network resources - but
intermittently and randomly the vpn connection dies.

The strange thing is that userA drops out while userB is still connected.
There are 8 remote users connecting like this. It happens to them all.
I have tried a new router (in the remote office).

Any ideas?
