Error #2032 on new W2K8 install

Forum,

I just installed Adobe Media Server v5 on a W2K8 R2 vm.  Testing from the admin console I get an error #2032 for all of the samples except for "Single Bitrate".   I tried to follow the discussion in thread1245961, but there wasn't enough into.  Perhaps related; compared to a v4 installation, the Application Pools and Web Sites in IIS are missing the entries present in v4.

Any help would be appreciated.

Thanks,

Mark
