Ok Ok Ok !!!
I'll make an image of one of the clients and expose it unfiltered to the sesspit out there that is the internet...
Lets see what the XP2 firewall thinks of it all !
At least I can put the image back afterwards !
I'll let you know how I get on...
I know that I may have sounded short, but this problem has been infuriating for the last 6 weeks now - please rest assured that I *do* appreciate everyones help.
Cheers,
