XP SP2, VPN and Exchange connections ...

[Guest]

After deploying XP SP2 to all VPN users - they are no longer able to connect
to the Exchange server through VPN. It tries and tries and tries with no
success.

They are able to ping the server - but Outlook never connects to it.

Firewall in SP2 has been turned off on each client.

Has anyone seen this or know how to fix it without having to uninstall SP2?

Regards,

Mike

Casey,

I'm not using ISA server. How is this going to help?

So what VPN (IPSec or SSL) software/device are you using and what VPN client
software are you running?

We're using Sonicwall 3060 with it's Global Vpn Client.

The issue that we started seeing this activity after SP2 was installed.

The other really weird thing is - it's not every VPN user on SP2 - maybe half
of them.

I don't see the Sonicwall VPN Client on the list:
http://support.microsoft.com/default.aspx?kbid=884130&product=windowsxpsp2

But it wouldn't hurt to:
1. On a machine with the problem, uninstall, reboot, and reinstall the
Global Vpn Client and then see if it now works. The SP2 firewall and VPN
Client both play with the same networking shims and SP2 modified a whole
bunch of things, so there is a possibility they are interfering with each
other. Although none of the other VPN vendors appear to have a
problem--Cisco, Nortel, etc.
2. Send Microsoft a message with any debug information you have.
I would send a sniffer trace to show what packets are being sent and what
isn't.

I Googled just in case and only found this reference to Sonicwall:

Did you change any other settings prior to the SP2 install?

Phil,

We're not having VPN issues, we're having Outlook connectivity issues with
Exchange while VPN'd in. Prior to SP2 being installed on the clients - we
didn't have this problem.

I'm not sure uninstall/reinstall the VPN client will fix this. I can
certainly try - i'm willing to try anything at this point - but I believe it
will not fix the end users problem.

See if any of these can help.

Outlook 2000 'sluggish' with XP SP2:

Is Outlook Web Access (OWA) working?
There are a ton of articles on XP SP2 ad OWA having problems.

Also, you may want to throw this to the Exchange forum to address.

At this point, I don't think it's anything to do with your VPN connection,
it's something with XP SP2 and Outlook communicating with Exchange.

You should include versions of Outlook and Exchange for that discuss.

Good luck and sorry we couldn't help more.
