Good afternoon, I possess Windows Server 2008 R2 x64, I need to uninstall the web server completely (IIS), because I intend to use the server Apache in his stead.
In the server manager panel right-click on Web Server (IIS) and chose Remove Function Services.
As image in attachment, I cannot click next to continue the removal. I believe I need to uninstall something first. Can anyone help me?
Thank you.


Try stopping the iis service in "services.Msc" before uninstalling. Needs Administrator scrolling.

I stopped the following services: Application Host Helper Service (APPHOSTSVC), IIS Administration Service (IISADMIN), Windows Process Activation Service (WAS), ASP.Net Status Service (aspnet_state), World Wide Web Publishing Service (W3SVC). The problem still persists.

If the service is disabled and/or no one else is using the port, you can install apache and use port 80. It should already work.

Take a look at the penultimate command of this Technet.

Checks whether the
WAS(Windows Process Activation Service) is installed before proceeding, if it is you will not be able to uninstall theIISbecause he is dependent.– Felipe Assunção
