I get "Overlapped I/O operation is in progress" error when i try to add a new NNTP Virtual Directory to IIS for setting up Exchange Server 2003. Unfortunately I didn't do this until after forestprep and domainprep operations for Exchange Server 2003 ... And the Exchange 2003 installer complains that NNTP is not enabled on the server. Is there a workaround available for this?
Also , can forestprep and domainprep for Exchange Server 2003 be undone?
Appreciate any feedback.
