You can run it without shutting down Exchange. Still a better process to run it after hours though. Just no need to shut down Exchange to do it. -----Original Message----- From: James Dykes [mailto:jdykes@xxxxxxxxx] Sent: Wednesday, February 02, 2005 10:54 AM To: [ExchangeList] Subject: [exchangelist] adprep question http://www.MSExchange.org/ Just a quick question... I have Exchange 2000 running on a 2000 box and I have a new 2003 box that I'm going to install Exchange 2003 on. Since this is my only email server it's kind of hard to take down due to users getting email and all. I have another server (2000) which is my domain controller. Is it safe to run the adprep /forestprep and adprep /domainprep utilities on the domain controller while my current Exchange server is on and running or should I come in after hours, shut exchange down and then run the adprep utilities? Thanks in advance, James ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: World of Windows Networking: http://www.windowsnetworking.com Leading Network Software Directory: http://www.serverfiles.com No.1 ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSEXchange.org Discussion List as: al.mulnick@xxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Report abuse to listadmin@xxxxxxxxxxxxxx
