ISA server has a corrupt rule

[jonnyknowsbest]

Somehow our ISA 2004 Server has got borked. There is a particular rule, that when you try to click the "Networks" tab, a "Fatal Error" is displayed. ISA itself is working ok, but if we try to make any changes and apply them, the same "Fatal Error" occurs (that includes trying to delete this rule)

Does anyone have any ideas as to how we can remove this rule without re-installing ISA?

I have managed to get to the bottom of the problem myself. Thought i'd post the solution:

I tried right clicking and deleting the rule. Although this "works", it gives me the "Apply / Discard" prompt. If i click "Apply", the fatal error comes up. However, if i leave this message on screen, ISA is left in a "non-committed" state. I then right clicked and deleted the rule again, and it disappeared.
