Environment
---------------
Windows XP Pro SP3
Set up a VPN Server using the Windows XP built-in VPN Server software

VPN Client
------------
Windows XP Home, Windows Vista
Use the built-in VPN Client

Issue
------
Using a PC, connect to the VPN Server and network - OK. With the first VPN
still active, use a separate PC and a different user account to make a VPN
connection. I have got this error message:
"Error 937 Because another connection of your type is in use, the incoming
connection cannot accept your connection required."

If I log off the active connection, I can make the connection from the
second PC. With this connection active, I try to log on from the first PC.,
the same error message appears.

It appears the Microsoft VPN Server cannot serve more than 1 VPN client. Is
there a way to increase the number of concurrent VPN connections using
Microsoft VPN Server software?

Thanks.

AFAIK not possible on XP. You'll need Server 2003.

Windows XP by design is a "single" user version of Windows. You need
to completely re-think your VPN "server" configuration so as to use a
"true" server or a VPN end-point enabled router.

No, you can not via the VPN server software. However, this link may provide
you with a solution. It is designed for RDC but .... side affect may be an
increase in VPN connections.
