VPN client disconnects after 60 seconds.
Posted on 2006-07-10
Client is Windows XP/Pro connecting on VPN (PPTP) to SBS2000 server. Authentication is with Active Domain Remote access. I have 5 or 6 users connecting from home using the Windows VPN client, authenticating with ID/password in AD.
Everyone works fine, and can remain on as long as they want. (No default time off idle values set). The issue is only one of the users connects, and is working for 60 seconds then disconnects. (Event20148 in the System Log says user initiated disconnect) but the user did not disconnect. Every connection by this user is followed by a disconnect after 59-61 seconds. Two weeks ago, she worked from home and was online for 4 hours. What could have changed? I am the server admin. She is the only one having an issue. I have walked her through delete and rebuild the VPN connection on her PC.
During testing, from her side, we have turned off, disabled all firewalls. Whatever allowed her to work 2 weeks ago is obviously gone or not present now.
