With an active VPN, one client no longer browsing remote server.
Posted on 2005-04-26
We have an active and working VPN connection between Denver and Milwaukee using a Watchguard 5 on both ends. There is a server in Milwaukee that serves as both Exchange server and file server. In Denver there are only client boxes and they all plug into individual ports on the Watchguard 5.
This solution has worked fine for over a year. The Denver clients have all been able to properly retrieve email from the Milwaukee Exchange server and have also been able to map and access the Milwaukee Data drive. About a week ago, only one of the clients began have problems with refreshing email from Exchange - with some parts of the process succeeding and others not. During this same week there was a bit of a slowdown with accessing the data drive in Milwaukee.
As of today, still only one machine in Denver is affected. On the affected machine:
1. We can ping the Milwaukee server using either the server name or the internal ip address
2. When opening file manager, the Milwaukee data drive mapping to "M" appears active and displays the correct used/available diskspace of that drive. But, when trying to open that folder we time out and get the error:
"An Error Occurred while reconnecting M: to \\server01\Data
Windows Microsoft Network: The local device name is already in use.
This connection has not been restored"
At this point the "M" drive mapping now indicates disconnected.
3. When opening Outlook we do not receive a login error or a request for username and password. Outlook appears to be opening properly for a few moments and then the "retrieving data" dialog box appears. Progress seems to be indicated by the moving bar for about 5-10 minutes, but it eventually becomes clear that it has hung. After finally giving up on the refresh, cancelling the retrieval gives us the "cannot display folder" message.
This same machine can surf the internet with no apparent difficulties or slowdowns. No changes to the machine, or the server, or the vpn settings were ever made to create this problem.
Is it possible that the network card on this machine is dieing; still working well enough to find view the web, the Milwaukee drives and the Exchange account, but not working well enough to actually work with the folders and exchange the data?
Or, any other suggestions?
FYI - I have already tried changing out all connectors and ports with other machines. Also, I can access all services correctly as this user when doing so from a different machine.
Well - I threw in a new nic card and no such luck.
