IIS working or not?

[jash]

Hi
I'm running XP Pro and have installed IIS on a Pentium 4 machine. However although it claims to be running (in the Services list), I am not always able to access the control panel. When I go via admin controls and click on it, the cursor twirls around and then nothing. No icon appears in the task bar.
I have been able to get the control panel running but I can't remember how.
I want to test out some .asp pages using dreamweaver ultradev.
When I have got it running, I seem to have to set up the guest account to enable functioning of .asp pages each time after reboot.
Any ideas?
