Named system database issue. Invalid object DYNAMICS..SY01500

I have a production and development environment on separate SQL instances for a new client. In my PROD environment my GP system database is named 'DYNAMICS'.  In my DEV environment, my GP system database is named 'DYNDEV'.  

I restored my DEV company database from a copy of the PROD company database.  

After the restore, I ran the CompanyUpdateDBName SQL script from  KB871973.  Before running the script, I updated the script so the system database reference was correctly 'DYNDEV'.  I then ran a SQL script to update the DBNAME field in my company..SY00100 table.

Now, when I try to log into the DEV company, using the correct ODBC, I get the following error messages:

[Microsoft][SQL Server Native Client 10.0][SQL Server]Invalid object name 'DYNAMICS..SY01500'.

Then:

The stored procedure smCleanupFilesBeforeLogin returned the following results: DBMS: 208, Microsoft Dynamics GP: 0.

I followed KB849708, which I found after searching on the 2nd error message.  But I still get the same error messages when I try to log in.

So there's a reference to the PROD system database somewhere, but I don't know where.  

Any ideas?
