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:
Log Name: Cisco AnyConnect VPN Client
Date: 9/21/2010 9:15:42 AM
Event ID: 2
Task Category: None
Invoked Function: WSAGetOverlappedResult
Return Code: 10060 (0x0000274C)
Description: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
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?
