There are some changes to Active Directory between SP1 and SP2<br />
a LOT of people did not RTFM and did it without<br />
updating AD<br />
and running ADPREP<br />
and FORESTPREP<br />
<br />

</div>


<div>
You are going to have to <br />
<br />
refomat and install 2003 SP1<br />
install all the updates...<br />
<br />
make an image of that install..<br />
I suggest Norton Ghost..<br />
<br />
install this image an the 51 other servers...<br />
unplug them from the network...<br />
reboot..<br />
Change the ip and computer name...<br />
reconnect to the network and reboot...<br />
<br />
That is the easiest way..<br />

Thank you very much for your commments; I tried to isntall 2003 SP1 several times; but the media I got from HP is a bit different from the standard Microsof ( I am attaching you an image of the media I got).<br />
<br />
This media, doesn't allow to install a single 2003 SP1, always finish and match with SP2. so, I wonder if Is possible any other path to roll-back??

Hello,<br />
<br />
We installed 52 HP Proliant Servers with OS Windows Server 2003 R2 SP2 Ent. Ed (ROK License bought from HP); but we realize that the main application is not suported for SP2, In fact the developer of this application will not provide us any support if we keep running over SP2. So, I need to know How to roll-back from SP2 to SP1 in order to run this application properly and keep the OS stable?<br />
<br />
Thank you

How to roll back Windows Server 2003 R2 from SP2 to SP1?

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
