problem with credentials after RRAS PPTP VPN fails to connect.

I've had this with two Windows 2000 servers, actually SBS 2000.

In one case the VPN was to another W2K server, in the other I think it's a
VPN concentrator (very close mouthed 3rd party).

A permanent demand dial interface was created and successfully connects. If
for some reason the link fails (local or remote loss of internet) the
connection attempts to re-establish a number of times. If some limit is
reached the connector no longer tries to establish. At this time the system
suggests the credentials for the connection have not been set. Nothing can
be done at this point to re-establish the connection, except restart the
server. When the server is restarted the connection is again established
without setting the credentials.

We have tried resetting the credentials.
We have tried restarting relevent services (RRAS/ISA).

any thoughts appreciated.
 
It doesn't surprise me this message has not inspired response, I've also not
been able to find any information anywhere else.

Does anyone have ANY comment at all? PLS?
 
I have never struck this myself, but I seem to recall it cropping up
in the newgroup some time back. Is the VPN set to initialise from either
end? The remote site might be busy because it is trying to re-connect. In
the MMC, does the connection status show up as unreachable?

There is a table of what happens if the connection goes to unreachable
in KB 262990 (which is about failover). Apparently the attempts get slower
and slower pretty dramatically.
 
There is a current posting from Sander Weijers in
windows.server.networking on a similar topic that might be worth a look.
 
tks Bill, I'll duck on over and have a squiz at at Sander's thread.

In your earlier reply you ask about initialisation from the other end. No,
in my cases the VPN is only initiated by the systems under question.
 
Though I don't hold a lot of hope after looking at the post it has sparked
an idea. To implement multiple DOD interfaces with different metrics. I'll
explore this.

tks ur thoughts.
