This is not a known issue, the SP1 installation overwrites the files
that is included in MS03-039 with newer versions of those files.
I would think the third party scanning program have a logical flaw for
this issue.

824146 (MS03-039) is listed here as included in SP1:
Windows Server 2003 Service Pack 1 list of updates
http://support.microsoft.com/kb/824721/
As long as the following files (in the System32 folder) have a version
number of 5.2.3790.1830 or higher, you are good:
ole32.dll
rpcrt4.dll
rpcss.dll
(MS05-051/KB902400 will upgrade the version number to 5.2.3790.2492 for
ole32.dll and rpcss.dll).

No, but installing MS05-051/KB902400 is an option, it supersedes
MS03-039:
Vulnerabilities in MSDTC and COM+ Could Allow Remote Code
Execution (902400)
