- try reducing the MTU for the VPN connection – VPN, wireless, possibly DSL keep adding to the packet size; and possibly you’ve exceeded the allowable frame size. Try 1100 or so rather than the default.

If so make sure the vpn is pointing to the correct default gateway in order to get to the internet. In short if she is using web access through the vpn most vpn’s are defaulted to not allow internet traffic. At least in XP that is. Hope this helps.

Any other suggestions would be appreciated

Have you been able to resolve this issue as we have the same happening with our own connection.

Would appreciate any assistance as we have exhausted all research on the Microsoft web site

We have a Cisco 3000 concentrator , VPN client 4.6, and the laptops are running Windows XP. They can connect through the VPN with no problem, but when they open Outlook, the system hangs on “trying to connect”. I can ping the Exchange server. Seems like an authentication issue but I can’t find where it is. When the users connect to the network when they are in the office, there is no problem.

The only thing I can think of is that maybe she has static wins or dns entries that are presenting a problem for her.

I’ve seen similar situations where a DC was on a 192.168.1.x/24 segment and the user was unable to authenticate because their home network was on a 192.168.1.x/24 segment and the redirector on the machine was sending the traffic to the local network rather than tunneling it to the corprate network.
