Hi Everyone,
For quite some time now, we have been experiencing an issue with the Cisco VPN client that will make the client completely unusable. I have noticed that when a specific feature of Symantec Endpoint Protection is enabled, it will (about 25% of the time) cause the following errors to appear when attempting to connect anywhere with the Cisco VPN client. Once this error happens once, the VPN client then becomes useless.
Error #1
Reason 414: Failed to establish a TCP connection
Error #2
Reason 440: Driver Failure
Error #3
Reason 442: Failed to enable virtual adapter
It seems that fixing one error will cause the other error to come up...
I have tried reinstalling the client with the same version and older versions and the issue still comes up.
All users in the company are using Windows 7 64-bit with SP1 installed.
The oddest thing about this is that all employees in the company have the same antivirus with the same features enabled, however, it only happens to a small percentage of employees.
Please let me know if you have any suggestions and thanks in advance!
