I had ISA working beautifully on a Dell Poweredge 6300 in a test situation with just a couple of users on it. I then realized that my RAID 5 was not set up correctly, so I made my corrections, formatted the machine and started over. I used the same name and IP address for the ISA computer, but cannot get internet access now. I get HTTP 502 Proxy Error...The ISA server denies the specified URL. I can ping my gateway fine as well as other servers that have external nics on the same subnet, so I think connectivity seems okay. I pretty sure it is something simple staring me in the face, but I can't seem to spot it. Any help would be greatly appreciated. John Martindale jmartindale@xxxxxxxxxxxxxx
