Problem creating Active-sync virtual directory when reinstalling Exchange 2007

Have you opened IIS manager and checked "old" virtual settings?

The old virtual settings are gone since we reinstall the iis.
I tried to manually create the virtual directory but then i get the message that a virtual directory with the same name exists.

The installation have created the following directories; Autodiscover, Exchange, Exchweb, OAB, owa, public and UnifiedMessaging.

So it looks like it's only the active sync directory thats not generated.

Thanks als315 for trying to help me.

The Remote Regsitry Service is started.

I will try to install the exchange without CAS role an then add that role from shell afterwards.
