Can not execute ASP files with <%@ Language=VBScript %> in IIS 6.0

We were getting HTTP 403 forbidden access error on our web app (which is hosted on Windows 2003 server); to duplicate this issue locally I made changes to our test Server and changed ?Execution Permissions? to None; after that I was able to duplicate the issue.

Later I change the setting back to ?Scripts only? and ever since, we are experiencing an issue when server is not processing (and hangs) requests where ASP file has ?<%@ Language=VBScript %>? tag; all other ASP page with ?<% %>? tag are processing fine.

Does anyone one know how to resolve this issue?

Thanks.
