Failure to access the DBMS server

I�??m getting a �??Failure to access the DBMS server�?� error when I try to create an ArcSDE geodatabase in ArcCatalog 10.1.  Someone else had a similar problem:

I�??ve tried everything mentioned in that forum but I�??m still having trouble.  Here�??s my setup:

Installed on my 64-bit Windows Server 2008 Server:
- Microsoft SQL Server 2008 R2 (64-bit)
- ArcSDE 10.1 for Microsoft SQL Server
- ArcGIS 10.1 SP1 for Server - Enterprise (Advanced)

Installed on my 64-bit Windows 7 Desktop:
- ArcGIS 10.1 SP1 for Desktop - Advanced (ArcInfo)
- Microsoft SQL Server 2008 Native Client

The installation of ArcGIS Server was a completely clean installation; no version of ArcGIS Server had been on the server prior.  When I recently upgraded a server that had ArcGIS Server 10.0 on it prior, I encountered no trouble.  It makes me think there was a SQL or Windows setting that I changed long ago in 10.0 that carries through but I can�??t think what.  I�??m an administrator both in Windows and in SQL.

I would greatly appreciate help so I can stop banging my head against the wall.  :)

Thank you!
