Hi to all.
I am facing a problem where Discovery accelarator virtual directories and the Application pools in its IIS are missing.
Any ideas how to rebuild them? I do not know how those directories got lost from IIS, so anything would be useful.
Try to disable UAC on your server, and re-install DA.
Have you all prerequisites in green at the begening of installation of DA ? I think especially at the "IIS 6 Management Compatibility" and "IIS Management Scripts and Tools".
