Web Adaptor -->Error when firing it up

I installed the web adaptor for IIS   with no issues but when the initial web page tries to come up I am getting the below error.
My IIS settings have all the requirements listed in the help doc. I believe my machine meets all the system requirements.

I installed successfully to Win2008r2 successfully off the exact same ico image. The web page came up no problem.

Server and IIS seem to be running fine I have been able to publish services, create web apps (js), etc etc on this laptop.
I have the System.Security assembly registered in my C:\Windows\assembly folder.

I can't think of what may be causing this.

I have unistalled Web-adaptor and re-installed, no luck.

Possible related link:

Win7 sp1 (hp laptop)
ArcGIS_Server 10.1 (sp1)
IIS (6.1) and ArcGIS server installed on same machine.
no Citrix
no windows domain account
no active Directory

Thanks for any clues
