I recently needed to enable tracing on IIS for Windows Server 2012 and thought its worthwhile to share for others.

· Go to Server Manager and Click Manager(Top Right corner):

· Pick Manage and Add Roles and Features:

· Click Next on below screen:

· Pick first option as below screen:

· Choose server on below screen and click Next:

 

· On Next screen expand Web Server:

· Pick Tracing as shown in below screen, Click Next:

· Click Next on the below screen:

· Click Install on below screen(Tick Restart checkbox if needed):

· Click Close once Installation is complete:

You are done. Hope it helps!
