I have found the problem with our network. The problem was our ASA5510. There was a setting in the access list that was causing this problem. It was blocking all internal traffic to our main server. once we did a “NO…” command for it everything is fine on the network.

Thank you to all of you who have helped me in this effort to solve the problem!

Monitor your bandwidth usage on the WAN if your equipment has the functionality; you may have to use some third party software and mirror the port. This will help you diagnose the issue.

You can also test connectivity by sending an unlimited ping from one side to another to see if there is latency and packet loss at certain times of the day. That will also give you a secondary keep alive.

I’ve checked the event log. nothing seems to be showing an error to relate to the connection to the network being dropped. could there be a issue in GPO that might cause this connection loss?

I will check the log next time it happens and let you know. The VPN is set to keep alive for sure, just checked that.

Intermittent problems are the hardest to figure out. Check the event logs to see if there are any errors around the time that the connection drops. You should also make sure there is a keep-alive; if the VPN becomes inactive after a few minutes of inactivity, that may be causing the problem.

ok, I see what your getting at now lol. Easing my mind is one thing, but I do need to fix this problem on my network. Where might I look to see what is causing the problem? the main problem is in the local office to the server. The software my users are using is a LIVE SQL base software. When the network connection drops for the unknown reason the software freezes and the user may loose some work they have done. once the connection has dropped they must reboot to get back on the software or the internet.

This does not happen all at once with every computer getting dropped, just every so often 1 will drop.

I don’t see any problems with the script, but to ease your mind about this script, you can do as I mentioned before which is replace the script with a batch script for each group by using the NET USE command.

The login script would not be the reason why these drives disconnect. I’m thinking this is a more ominous issue with your network or VPN.

the issue that I’m trying to get at is that I belive this VBSscript is causing some conflicts…

In the script above our company only has use for these script lines
______________________________________________________
‘Map drives needed by all
‘wshNetwork.MapNetworkDrive “z:”, “\**SERVER NAME**users” & UserString,True ‘Basically maps home drive
‘wshNetwork.MapNetworkDrive “s:”, “\**SERVER NAME**common”,True

____________________AND_______________________________
Case “administrators”
wshNetwork.MapNetworkDrive “t:”, “\**SERVER NAME****FILE NAME**”,True

____________________AND_______________________________
‘Call WSHShell.Run(“cmd.exe /C \serverfolderfolderfolderscan32.exe”)

‘Quit the Script
wscript.quit

_______________________________________________________

as I have stated, I’m not an expert in scripts, but can I take out some of the unneeded entries in the script and it still function as it should? and could some of this be causing us problems?

this is a login VBSscript in GPO for the user group. Our VPN connection is not dropping it’s just the mapped drives on re-map and some of our users have roming profiles and they will not re-sync once connection is dropped.
