Hi

I have a VPN between Server2 and Server1. Server2 always initiates the
connection to Server1. If the VPN "goes down" for some reason, on most
occasions (not all) Server2 must be rebooted to reconnect to Server1.

Any ideas.

Thanks
Jeremy
 
Need lots more information:

How are you connecting? PPTP or L2TP?
What error do you get when trying to reconnect?
Which OS versions are you using?

I'm using PPTP. There are no errors, it just sits there forever counting
through the seconds (if a manual connect) without connecting. Windows 2000
Server SP3 (at both ends).

Thanks

If you can fire up netmon and compare a successful call to the one that's
failing, it may provide some more insight.

Also you might want to do a "route print" and a tracert before and after.

Finally, are you connecting by name or by IP address? If by name, try to use
the IP address in the connection.

Also, you can compare logs in your tracing folder...

<fire up a command window>
netsh ras set tra * dis
xcopy %windir%\tracing\* %windir%\tracing\old\
del %windir%\tracing\*
netsh ras set tra * ena
cd %windir%\tracing\*
<repro your problem>
dir <to verify that logs contain info>
notepad PPP.LOG

The netmon idea is to see if the PPTP protocol is doing something strange,
but the idea is to try to find out what changed on your system between
connection attempts?

Does it ever connect or just hang there "forever" (like over 20 minutes)?

You can also compare a "netsh ras dump" and "netsh rout dump" before the
first connection and before the 2nd failing connection.
 
I first found out that stopping and starting the ISA Server Firewall service
allowed the RRAS to re-connect, however I subsequently found that disabling
the (default) RRAS option to negotiate multiple connections has completly
solved the problem. This surely must be a bug in the software somewhere.
This problem has plagued me on multiple installations over a long period of
time.

Thanks
