Hi, Please can anyone help here. We use personal certificates generated from a Microsoft Cert server for use with our cisco VPN client for remote access. The problem we face is each time the user changes their domain password, the certificate installed for the VPN no longer works. This means each time the password is changed the cert has to be regenerated. Only when the certificate is renewed does the VPN work again. Can anyone assist with what could be going on. I've spent ages researching this problem, but to no avail. Thanks for any input!

Hi, To make the issue clear, may I know the following: 1. The type of VPN, L2TP, PPTP or etc. 2. The exact error message appeared when the VPN connection failed with this issue. 3. How do the users change the password, press “CTRL + ALT + DELETE” and then select “Change a password”? 4. Do only Windows 7 clients encounter this issue? 5. The server operating system of your Microsoft Cert server. Considering this issue is related to your server, it is also recommended that you go to Windows Server forum for help: Windows Server Forums Thanks. Nicholas Li - MSFT

HI, Thanks for the response. Users are changing password when prompted from the DC. The server OS is 2003R2/WinXP. As soon the user changes the login password, they are no longer able to connect to the VPN. Is it possible that the branch DC is somehow instructing the CA or the client to revoke the certificate installed? Client certs are installed via internet explorer to client computers. Apologies for being in the wrong forum.
