Connection often drops briefly

Unanswered Question
Sep 21st, 2010

Hi,

I am running Cisco AnyConnect VPN Client Version 2.4.1012 on Windows Vista SP2.  Recently I have started having the following problem when connected to my VPN:

My PC's internet connection will drop for about 60 seconds.  All internet traffic will fail during this time and then everything will come back.  This only happens when I am connected to the VPN.  It seems to occur more often when I attempt to run a remote desktop session through the VPN to any of my servers.  However, the connection will drop sometimes even when I am doing nothing.

I have discovered the following event log entries in the AnyConnect event log that correspond to me losing my connection:

Description: SOCKETTRANSPORT_ERROR_TRANSPORT_FAILURE

These are followed by more SOCKETTRANSPORT_ERROR_TRANSPORT_FAILURE entries and then the entries show that the connection is being re-established.  There are additional errors in the event log during the reconnection, but I don't want to post them all.

To me this looks like the VPN client is just reacting to the loss of the internet connection.  So I don't know if this gives me any information.  However, this loss of connectivity only occurs when the VPN client is connected.  I do not see any additional event log entries in the Windows System or Application logs that would be relevant.

Anyone have any ideas on how to trouble shoot this problem?

Thank you,

Kevin

I have this problem too.

Go ahead and get a DART output, it will tell you what could be causing this

Are you getting the problem on another PC?

Are you downloading the Anyconnect automaticaly at a time to connect? if yes, try having it installed on the PC, stand alone connection
