check port 80 when you run into problems while starting IIS

When you get an error while starting IIS on windows vista, try to check what are the other services running on port 80. Probably some other services(like apache) should be running on that port.

Open command prompt and type the following command

netstat -o -n -a | findstr 0.0:80

Result will be something like thisTCP 0.0.0.0:80 0.0.0.0:0 LISTENING 2032 (here, 2032 is pid)

Now open window task manager to kill the process. Once the process is killed, there shouldn't be any problem to start / run the IIS on IIS manager.
