Server: PIII 800 256MB Ram Win2k Server SP3 + Hot fixes ISA Server When attempting to install Service Pack 1, I receive the error, ISA Server not installed. The ISA CD is the MSDN CD, which I've used on previous installs and service pack 1 applied fine. The proxy is working fine, it's just I have some issues with being able to see the reports on remote ISA Management installs, but on the server I can see them fine. I also have some other repeated Auth prompts, which was fixed at a previous site with Service Pack 1 being installed. The 2 solutions I can find on the net are: 1) Reinstall ISA server and use the same config (Backing up first just incase) 2) Add a registry key, but the tree above the key does not exist, nor does the setup.stf file in the ISA Proxy directory Any suggestions would be appreciated, Thanks, Tom
