I'm having some difficulty upgrading Reporting Services 2005.  I originally
performed an upgrade using the MSDN version with no problems.  Now that that
select media is available, I wanted to run through the same upgrade with
that.  So...  I had the box reformatted, installed SQL 2000 and RS 2000 so it
looked just like our production box and tried to perform an upgrade.  I've
re-run this twice now and always get an error message:

SQL Server Setup has encountered the following problem: [Microsoft][SQL
Native Client][SQL Server] Cannot insert duplicate key rwo in object
'dbo.ConfigurationInfo' with unique index 'IX_ConfigurationInfo'.. To
continue, correct the problem, and then run SQL Server Setup again.

The only thing is, I've verified there are no duplicates prior to the
upgrade.  I really don't want to install from scratch and redeploy the entire
site, any help is appreciated.
