Re: Unable to establish the VPN connection. (Error 800) in SBS 2003

Hi Holger,

You should fix the task offloading as that indeed can have impact. Also,
make sure you have installed all the updates on the server. You might be
suffering from a result of a DNS patch last year, for which you would need
to add some keys in the registry, but if you install all the updates, it
probably should have them:

Hi,

sorry for not copying the history of the thread.

Overview of the situation:
- We tried to connect some clients over VPN, but we did receive the
following error message: Error 800: Unable to establish the VPN
connection. The VPN server may be unreachable, or security parameters
may not be configured properly for his connection.
- Then all of a sudden the connection worked, the only thing we did was
a reboot of the server
- Now 16 days later we did another reboot and we are back to the same
problem Error 800

What I have done:
- We run the configure remote access wizard, VPN access was enabled
- We did run the CEICW, like I mentioned before I have tried it with
the Firewall disabled, didn't work either. So I have enabled it
immediately again by running the CEICW again

What I have done now:
- I did run the SBS BPA and I received two critical issues:
1. Three or more network adapter cards are detected.
First two cards are for the LAN and the WAN
The third card we do have installed is a AVM ISDN-Controller FRITZ!Card
for the fax

2. Task offloading is enabled

Can any of those problems be the root of the issue we are having?
