Windows BPA is reporting the following:-
Issue: The value set for the registry key at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\90\Machines\OriginalMachineName does not match the current name of this computer.
Impact: This can prevent applications that install a SQL Server instance from installing the instance successfully. The error: "No mapping between account names and security IDs was done" may appear.
Resolution: Open the registry editor and change the value of the OriginalMachineName registry key to match the current name of the computer.
When I open Regedit and locate the registry key under "...\Microsoft SQL Server" , there is a key "90" but also a key "100".
If I expand key 90, there is no keyname called "machines". However, if I expand key 100 there is a registry key called 'machines' and the value in there is as follows:
OriginalMachineName REG_SZ SERVER
This is the correct name for the server.
I can't figure out why this BPA warning keeps generating.
