FYI, I was able to get the services started again by removing the offending rules in the registry: The proxy access rules were located in: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Fpc\Arrays\{8C1A04E2-8663-4179-9288-24F4C10EDD03}\ArrayPolicy\Proxy-Access-Rules There was also a corrupted destination set that i had to remove in: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Fpc\Arrays\{8C1A04E2-8663-4179-9288-24F4C10EDD03}\PolicyElements\Proxy-Destination-Sets Cheers Anthony -----Original Message----- From: Anthony Ament Sent: Friday, 7 March 2003 17:33 To: [ISAserver.org Discussion List] Subject: [isalist] ISA Services failing due to missing trust. http://www.ISAserver.org Help! We had a trust setup between another domain, which has since been removed, however there was still reference to the users from the trusted domain in some protocol rules. Now the web proxy and firewall service will not start and when you go into protocol rules in ISA management it crashes with the error: "The Operation Failed - The trust relationship with the primary domain and the trusted domain failed." If bringing back the trusted domain is not an option, can the protocol rules be edited somehow to remove the reference to users in the non exisitant domain? Thanks Anthony
