Hi, All I'm not much new to use ISA Server 2000. But unfortunately I see an error, after reinstalling my whole server machine (Windows 2000 Server (Sp3) + ISA Integrated Mode (with all hotfixes)). Erro is "Configuration Error" Whenever I restart my server machine I see that error. Although I never see this error before. I don't know, why this time it occures. Please anyone who knows about this tell me. Thanks in advance.
