To put this into perspective... I'm into week #2 of my NT workstation not working. I went thru a series of NT4 re-installs, in the middle of that I had SP4, but when all was said & done I got rolled back to SP3. So now my DCOM stuff is hosed and C000005 errors are a noose around my neck.

So ok, I've seen enough hassles that I feel a little more confident in tackling SP4 update myself. I pulled down a NT4 SP4 folder from our network, including subfolders for i386, mdac, msie401, and ssx. I'm looking at the readme file and now I'm not so confident I should do this myself (I dont know a whole lot about NT unfortunately). The "before you install recommendations" state I should make a backup copy of my registry... how do I do that? It also suggests I disable any nonessential third-party drivers and services,I looked at the services applet in Control Panel, but I'm not sure what's non-essential.

I also heard rumor that there is a SmartUpdate deal for this on the M$ website... maybe I should go that route?

TIA!!
