Hi everyone For the last several years my ISA Server 2004 was working fine, but now when ever i open the ISA Server management snapin error comes The Operation Failed Deatils Error: 0x8000ffff Catastrophic failure well every service of ISA is working fine, and clients are not having any kind of problem. the above error doesn't let me create any kind of firewall rule. i can only able to enable or disable any rule created in past, But can't do any other thing? --------------------------------- Get your email and more, right on the new Yahoo.com
