I have a dozen computers running windows XP Professional. I have two separate domains(long story) within the same network. I have joined one XP comp to one domain, and a couple more to the other domain. The first computer that i joined to "COMPLAB" domain, works fine. BUt the other computers that i joined to the "473DOM" domain gives an error. It works fine if you log in with administrative priveldges, but if you log on as a normal user, it gives the error message of sometihng along the lines of "You cannot logon interactively", so... checking with other forums and help pages, i went into the Local Security Policy on the local computer.THen under User RIghts Assignment, I checked the Logon Locally option. Thats where i should be able to add permissions for people to logon right?? NOt in my case! On this computer the whole Logon Locally option box is greyed out. So this is where my dilema leaves me, it all works on one domain, but on the other the option is greyed out. Any solutions, ideas, or where you can point out errors in my logic, I'd greatly appreciate it.
