ADFS : Re-installing ADFS v2.0

Had a number of problems with this so decided to remove ADFS and re-install.

Un-installed it via Control Panel, removed the web site from IIS (Default Web Site) and deleted the adfs directory under inetpub.

When I ran the wizard again, all components correctly installed but the wizard complained that it found the web site so could not re-install. The message was "Existing web site detected".

WTF - I removed everything.

Mr. Google to the rescue and eventually I found the solution.

You need to run the command:

"appcmd delete app "Default Web Site/adfs/ls"

and

"appcmd delete app "Default Web Site/adfs/card"

"appcmd" runs under the command prompt and is found under "C:\Windows\System32\inetsrv".

Enjoy!
