Windows BPA is reporting the following:-

===========================================================
Category: Policy

Source: 221

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.

Try copying the key from 10.0\ to 9.0\  and see if that fixes the BPA extraneous warning. Which BPA are you using? i.e. which server version and which bpa is is showing up in.. i.e. wsus/exchange/...
