After the installation of SP1 the user was not able access the corporate VPN.

When trying to connect Vista hangs at "Verifying username and password" and eventually shows an 828 error.  On the server side event 20209 was logged.

There is a discussion on the ZA forums as to where the blame lies for the problem but there does not seem to be a clear answer.

For the sake of simplicity, I have found that:

On Vista SP1 machines with version 7.1.248 of ZoneAlarm free installed PPTP VPN connections to Windows 2003 Based RRAS servers do not work.  Also note that disabling ZoneAlarm does not help.  Uninstalling the product solved the issue immediately.

Always a pain when you try to solve one problem and create another in the process.  On a positive note Terminal Services easy print in Windows 2008 worked really well once we got the user reconnected.
