IIS7 and WAMP on same machine

To run Apache and IIS in same machine at same time. The port assigned to each server can be changed. I prefer changing IIS to port 81 and assign default http port i.e 80 to apache. The port changing in IIS7 and VISTA is done this way.

1) Run IIS
2) Click on default web site
3) Choose Edit Site ---> Bindings options from Actions pane in the right side.
4) click on the data available and click edit
5) change the port to 81 and host header to localhost
