IIS Admin For Windows XP Professional (20-10-2005)
If you are frustrated with the one website at a time limitation on IIS 5.1, then you should get this free tool from firstserved.
"IISadmin" is a nice little tool that allows you to easily create multiple websites on Windows XP Professional and to quickly switch between them.
