IIS questions/problems

I have been trying to set up IIS but this application does not want to start. I was told by people here to remove IIS from my system and reinstall it. I did that but it did not help at all .
Here is the problem. I click on IIS and my computer is not shown. I try to manually enter it but then it says dependancy failed to start.
I suspect that i have disabled a service from msconfig that is needed for IIS to work but i can not figure out which service is that.
How can i fix it ?

start with the IIS config service and under its properties check its dependancies and one by one check if they are set to auto or not. Then check the World Wide Web service and do the same, should at least leave ayou able to start the config screens.

where do i find all these properties and config service you mentioned?

right click, My Computer, manage, services
