No.  It will extend your schema and prepare it for upgrade.

If you need to raise the domain and forest level, you can read about it here:  http://support.microsoft.com/kb/322692

Commented:
It would not bring AD down, but I would do it after production hours.
 But I am overly cautious that way ;-)

Commented:
what version of AD are you on and what version are you upgrading to?

Commented:
No, it doesn't take it down but as advised, it's best to do after hours .....just in case.  Keep in mind that you can not revert it back to a lower level  unless you do a full forest restore

Commented:
FYI...the article I referenced covers all 'versions' ...

Thanks for the article. I was mainly concern about the consequence runing adprep.exe  /forestprep and ADprep /doaminprep when adding a windows 2003 DC to a forest level Windows 2000 and Domain functional level windows 2000mixed. I dont want to raise the domain levels currently.
