Exchange5.5 - install NT4.0 sp6a

Douglas,

Installing NT SP6a is a safe upgrade. The only thing you need to be aware of is that installing SP6a will cause Exchange to reindex the IS after the initial reboot. It may take a little while for Exchange to come up after the reboot. The reindex time is dependent upon your HW performance and the size of the IS.

If you have questions, please drop me an e-mail

Good luck :-)

I just did this on a costomers machine last night so I understand your concerns.

The upgrade to SP6a is a good thing. Just incase after you install the NT SP I would/have put the Exchange SP3 back on. I know, I know, this shouldn't need to be putback on.. but I'm a rather safe then sorry type guy. MS has been known to intergrate services and other software upgrades in their serives packs. i.e. there is a nice little Windows 98 patch that i.e. 5 puts on you machine, its a good thing but I wish that you could find it in the install log. =)

I just intalled SP6a on our Exchange 5.5 server, and have had no problems. I did not reinstall the SP for Exchange, but perhaps the gentleman that suggested the "better safe than sorry" approach is on the right track...now if I can only FIND my SP for Exchange! :)
