I previously posted here about 2 batch files for starting and stop BizTalk 2004 and SQL Server 2000 services.  The ones in this post, below, are for BizTalk 2006 and SQL Server 2005.  I use these for quickly and easily reducing memory usage (usually when I need to use VPC).  Enjoy!

StartBTSServices:

net start MSSQLServer
net start SQLSERVERAGENT
net start MSSQLServerOLAPService
net start NS$BAMAlerts
net start SQLBrowser
net start msftesql
net start MsDtsServer
net start ReportServer
net start MSDTC
net start RuleEngineUpdateService
net start ENTSSO
net start BTSSvc$BizTalkServerApplication
IISRESET /START
pause

StopBTSServices:

net stop BTSSvc$BizTalkServerApplication
IISRESET /STOP
net stop ENTSSO
net stop RuleEngineUpdateService
net stop MSDTC
net stop SQLSERVERAGENT
net stop NS$BAMAlerts
net stop MSSQLServer
net stop MSSQLServerOLAPService
net stop SQLBrowser
net stop msftesql
net stop MsDtsServer
net stop ReportServer
pause
