VPN disconnection

Hi

We have SBS 2003 R2 Premium with another Windows 2003 R2 Server as a member
server (additional domain controller).

We have been experiencing problems where, at certain times of the day, the
VPN connetion from clients keeps disconnecting. Sometimes seconds after we
connect the connection is lost again.
The symptoms for the disconnection are:
- We see the requests being sent (the LOCAL computer shows network
activity, sending to the VPN) but there apperas to be no answer from the
server. After a while the connection is lost.

Can you please point me out some clues on what might be causing this or what
should I do to troubleshoot the problem?

Thank you very much
Pedro.
