CAUSE

This error is caused by a known issue with insufficient permissions in the IIS metabase.

RESOLUTION

SUMMARY of TROUBLESHOOTING
==========================
This error is caused by a known issue with insufficient permissions in your IIS metabase. The metabase ACL's on the target server did not include the IIS_WPG group on the following two nodes of the metabase (IIS_WPG is in both ACL's on a clean install):
- W3SVC/AppPools
- W3SVC/Filters

You can download the MetaACL utility from http://support.microsoft.com/?id=267904. After you have installed the program, open a command prompt and navigate to the directory where you installed it. Then type the following:

cscript metaacl.vbs IIS://Localhost/W3SVC/AppPools IIS_WPG RE

Warning:
The path is case sensitive - type exactly as above; after you run this command restart the IIS services and see if this corrects the problem.

If this does not resolve the issue, this article may be of further assistance.
