Question

I have a sharepoint server on the DMZ and a SQL2008 server in the local domain.
When I try to get the list of .NETUsers for the Central Administration site from IIS (version 7.5) i get thrown error:26! I have tried all possible combinations in specifying the connection string.
I have also followed all directions on these links to resolve the isssue but it continues to persist.

Please advise.

Going from the Error itself, it turned out be a quite a complicated issue that ended up being resolved after a few days on the phone with Microsoft. The error read “The RPC service is Unavailable”. There were issues with the way NetBios and DNS was qualifying the site and server names.
