SP Level for Security Bulletin MS03-026

I have read and re-read and re-re-read the Bulletin. If I’m reading it correct, according to the bulletin, the OS’s affected need to be up to certian SP levels before applying the fix. I have had some mitigateing circumstances that have kept me from applying all the SP’s to all my servers. I have a mixed bag of servers rangeing from NT 4.0 and NT 4.0 TSE up through Win2k all in varrying roles. Does anyone out there know if there are any problems with applying this fix to servers that aren’t up to the SP level’s noted in the Bulletin?
