Vista Business, Wireless and VPN

I've read of a number of people who are experiancing this problem, but
haven't been able to find a solution. I use the built in Windows VPN
client to connect to the office. Was working fine with Windows XP -
whether I was connected to the internet via wired or wireless.

Since upgrading to Vista Business however, it works fine when I'm
connected via wired (no matter from where) but on ANY wireless
connection (tried both my own, and multiple others) it will not
connect at all. Internet connection is fine - I can browse with
wireless, just not connect with VPN.

I've tried disabling the wired NIC, and it's got nothing to do with
switching from wired to wireless - I've tried a clean boot several
times.

Connection to the server is via PPTP, using MS CHAP v2.

I don't want to have to reinstall XP, but if I can't connect to the
office it makes Vista useless for me. Help!

What's the VPN error code?

Interestingly if the flag on the Security tab of the VPN connection
that says "require encryption (disconnect if none)" is ON, the
connection fails immediatly. If it's OFF it takes a minute before it
comes back with the failure.

The error code in either case is 800.

CoID={6B7FF91E-3E44-479E-A8BE-9EE14058655B}: The user X dialed a
connection named VPN1 which has failed. The error code returned on
failure is 800.

And if it's relevant - my normal VPN connection is PPTP using MS CHAP
V2. Encryption is MPPE 128.

Hi, I have the same Problem

Vista Ultimate x86, VPN error 800 with wireless, no error with wired.
Disabling wired adapter doesn't solve the problem (I read somewhere that
Windows decides internet connectivity on the first found NIC).
Tried DHCP and fixed settings.
Internet access works and VPN Server is pingable wired (30ms) and wireless
(100ms).
The VPN connection also works fine with a Bluetooth dialup.

VPN Setup:
Security: No encryption, PAP only
Network: TCPIP4 enabled, TCPIP6 enabled, MS-Network enabled
VPN-Type: PPTP

The Wireless Accesspoint is plugged into the same hub the wired nic.

If anyone of the support staff should read this: Here is a copy of the
diagnostics report. It's a mile long and i can't make heads or tails of it.
http://musmabu-server.dyndns.org/ext...AS3E1F.tmp.htm
(I tried to attach it but the NNTP server wouldn't let me)

And: I read all the other stuff it doesn't apply or work.

Please someone help me :-)
Ivo

I have Vista Business and when I connect using my company's VPN it shows
connected but my NIC shows unidentified network, then it shut off the
internet. I cannot browse the internet or my company site. I tried setting up
Windows VPN still does not work. IT at work is baffled also. Any suggestions?

It could be the VPN client is using remote network gateway but that doesn't
allow you to access the internet. Post back the result of routing table may
help.

Right now I am connect but the NIC shows unindentified network and there is a
RED X on the line between network and internet. The line and the globe are
gray in color where they were blue before I connected. I cannot seem to see
the network card properties on this NVidia Network Controller.

This is a connected routing table with above error.
