We have a functioning VPN concentrator with WebVPN configured for users.
There are a few portforwarding rules that are already utilised by a number of users.
Recently there is this one PC that failed to work for the portforwarding.
The user logs into WebVPN, bring up the Application Access. The JAVA applet loads. Once completed , the user try to bring up the application that utilised the port forward rule, but it failed to connect to the server.
Other users are still using as per normal (no issues).
I am aware of the MS Loopback issue KB884020 and have also applied that patch, without any improvement.
I have even gone to the extend of reformatting the affected PC and reinstalling all the apps, but the problem still occurs.
