Installing Windows Server 2008 certificate enrollment Web pages

[Guest tcguy100]

Per the following KB article (http://support.microsoft.com/kb/922706), we

would like to install the Windows Server 2008 certificate enrollment Web

pages (on our Windows 2003-based certificate authority box) in order for

Vista boxes to request/process certificates. Prior to doing this, however, I

wanted to confirm whether our existing certificates would be affected by this

action. More specifically, would installing/upgrading to these new pages

cause existing certs to be removed or stop working? Any information would be

greatly appreciated. Thanks!
