If you have a spare 30megs on your HD, try the new uninstall directory
during installation. This will allow you to remove SP2 and get you back to
SP1 or whatever you were running with if you encounter problems.
Please be sure to read the readme.txt file before installing for important
information such as:
3.5 Microsoft DHCP Server
This version of the Microsoft DHCP Server modifies the format of the dhcp
database. You should back up the contents of your %windir%\system32\dhcp
directory prior to upgrading.
Here's the fixes section of the readme.txt which includes Q#'s for KB
articles written for fixes in SP2.
