Hi William, Pretty interesting! I'll have to stick that one away in the private reserve :-) Thanks!

I.e. it had no IP Addresses set and although this Client Address Set wasn't being used by any rule, it just seemed to cause a bit of a problem anyway. To fix I connected to the ISA Server from an MMC snap-in from a different workstation where I could then see that there was a problem and then simply removed the offending address set.

I have a suspicion that I have seen this problem somewhere else before but I am damned if I can remember where/why. I have resorted to restarting the entire server itself but that still hasn't resolved the problem. Does anyone perhaps have any idea as to what may be the cause/resolution? Cheers William R.
