IaaS prerequ checker "Not OK - IIS server"

Hi all,

I am currently installing vCAC. SSO & vCAC appliances were OK

I tried to install IaaS on a 2008 R2 & 2012 servers. I followed VMware documentation, install all prerequisites, tried Kendrick Coleman prereq powershell scripts.

But each time I got to prereq checker during installation, I got errors on "Not OK - IIS Server".

Everything else is green/OK, IIS module, rights, etc etc.

But prereq checker still continues to throw me IIS error : either IIS is not installed or running, or auth module is not installed, even if prereq checker checks that module are installed & configured...

Have you already faced this error ?

thanks,

vincent
