Hi Registry change. Have a look at the setting of HKLM\System\CurrentControlSet\Control\WaitToKillServiceTimeout parameter. The default is 20000, Exchange changes it to 600000 Cheers Raji Arulambalam Senior Systems Administrator Environment Bay of Plenty - Regional Council 5 Quay Street, P O Box 364, Whakatane, New Zealand -----Original Message----- From: Andrey.Ivanov@xxxxxxxxxxx [mailto:Andrey.Ivanov@xxxxxxxxxxx] Sent: Thursday, November 27, 2003 3:32 AM To: [ExchangeList] Subject: [exchangelist] Slowing down Windows 2003 Server shutting down after installation of Exchange Server 2003 http://www.MSExchange.org/ Hi, I have several servers running Windows 2003 Server and Exchange 2003 installed. Before installation of Exchange servers shutting down quickly, so rebooting does not take a long time. After installation of Exchange Server 2003 it lasts about 15-20 minutes. I have tried to down all Exchange services first, but it helps a little. Does somebody encounters the same situation? Does anybody have any ideas how to speed up the shutdown process?
