CISCO VPN on Windows 7 64bit

[JimFFlagg]

I am using the following:

CISCO 2811 router.
Windows 7 64bit
CISCO Client 5.0.07.0440 64bit
HP Probook 4530s - 4 GB ram; Core i5

The issue is we recently purcahsed new laptops for our inspectors. They where running Windows XP 32 bit with CISCO Client 5.0.01 and every thing worked fine. When I upgraded them to the new laptops I am having issues with the VPN.

The symptom is that the VPN connects ok and you can download files from the servers ok but when you try to up load a file that is larger than 80 KB it hangs on "Discovering Items..." then times out.

What I have tried is:

I hooked one of the laptops into the LAN and connect the VPN and the uploads work fine.

I setup a SoHo router in our DMZ and hook the laptop to it and I have the problem my users are having at home as described above.

Tryed truning off all Windows Fire Walls. -> Fails on upload.

Tryed stopping the "Indexing Service". -> Fails on upload.

Updated the CISCO client to the latest version. -> Fails on upload.

Removed Anti-Virus. -> Fails on upload.

Used IP addresses in place of FQDN. -> Fails on upload.

We have other Windows VIST 32bit computers and they do not have these problems with their VPN. These are our first 64bit computers. I really do not want to down grade to Windows 7 32bit.

I can make the running config available upon request but I doubt that is the issue being that our other computers are working fine but if there is something I need to do with the tunnel to get around this issue, I am game.

Any help on this would help a lot. I have already spent a day on this issue.
