Unable to modify MS Office 2007 files via VPN

August 23, 2010 at 11:24:31
Specs: Windows 7
Users on my network have access to a shared drive and have no issues with access while using the network from the office. When they go home and login via the VPN, they can still access their files, but are unable to save any modifications back to the shared drive. They must save it back to their local drive when it's an MS Office file. A WordPad or text file will save with no problem. When attempting to save an MS Office doc, the following error message comes up:

"There has been a network or file permission error. The network connection may be lost."

When the problem began, all users were using XP machines and the server was running on a standalone MS Server 2003 with no antivirus software installed when it was working and when it stopped. I had to move the shared drive to a new server due to the system drive running out of space. It is now located on a Windows Server 2008 domain server running antivirus software.

To sum up, users could save MS files via the VPN while on the 2003 server and it stopped working while on said server. Now their files are located on a better server running 2008, but users can still not save MS docs via the VPN.

Anyone know what the problem and the fix is for this problem???

They are using the same credentials for local access as well as VPN.

Of the groups created for this department, one is read only so they're not an issue obviously as they aren't supposed to be modifying anything ever.

Of the remain two groups; one has full control and the other has everything but full control. Users in both of these groups are experiencing the VPN issue.

Logon as a vpn user and check rights on the folders. Modify is enough, they don't need full control.

The users login with the same credentials whether via the VPN or locally. The file rights are the same either way. Over the VPN, they can create a text file on the shared drive, modify and and save it. But when they open a Word or Excel file, they are unable to save it back to the shared drive.

They are not able to open a file they could when local and can not save or do a save as?

If you logon as admin via the vpn does the problem still exist?

GPO's on the remote devices?
How are they vpning in?

Opening files aren't a problem via the VPN. It's when they try to save these files that they get the error message and have to save the file locally if they choose to save their work. At work, there's no problem at all.

Yes, even when I login as administrator, the problem still exists.

There is no GPO applied to this server.

They VPN in using Cisco's VPN client along with their NAC agent. If you're looking for more detail on the VPN path, I do not have that information. I have had the WAN engineer test it and he says there is nothing wrong with the VPN.

They are authenicating to the vpn router. It should not make any difference concerning access. It is all or nothing.

consider setting up rdp passthru the router [forward port 3389 to the ip address of the server]. If rdp works I would say there is a bug in the vpn client.
