I have XP SP2 machine with IIS 5.1 installed on it. Today I joined this machine to my Windows 2003 PDC. After joining to domain, I cannot access my web sites hosted on this XP IIS 5.1. However I can access web sites if I sit on this XP IIS 5.1 machine. I think something with permissions has created this problem. Web server is not accessible from other machines however on local IIS machine, it is working.
