Hi,
we have some troubles on one of our ISA 2006 Enterprise Servers. After installing the security updates from 12. April, no pptp vpn connections can be made.
On the routing and remote access console, there are no ports visible. After rebooting the server, the pptp ports are visible, until the first user connects over pptp.
Then, all ports are away.
After uninstalling the following patches, everything is working.

We are also using Remote Quarantine Agent features. Maybe it has to do something with this?
Is this a known problem? Workarounds?
Whitch Update could result in this problem?
Thank you and best regards
