At least most users don't even know it is there so don't put data into it!Mon, 05 Nov 2012 02:48:44 GMTP Joneshttp://www.sqlservercentral.com/Forums/Topic1379760-324-1.aspxThanks for additional info Steve and Paul - will try to check for these as wellFri, 02 Nov 2012 09:01:55 GMTStuart Davieshttp://www.sqlservercentral.com/Forums/Topic1379760-324-1.aspxThe instance name of the installed software may give a clue as to what installed it--the aforementioned Backup Exec instance is called BKUPEXEC, for example.Fri, 02 Nov 2012 05:33:26 GMTpaul.knibbshttp://www.sqlservercentral.com/Forums/Topic1379760-324-1.aspxWhen I worked at JD Edwards, OneWorld stuck an MSDE (Express) instance on client machines to cache some data.Thu, 01 Nov 2012 09:49:26 GMTSteve Jones - SSC Editorhttp://www.sqlservercentral.com/Forums/Topic1379760-324-1.aspxThanks for the replies - one of the net admin chaps here put me onto the Microsoft Assessment and Planning Toolkit which might give me more information to go on.Thu, 01 Nov 2012 08:45:54 GMTStuart Davieshttp://www.sqlservercentral.com/Forums/Topic1379760-324-1.aspxGus is right, quite a few applications use SQL Express as their backend these days. One I can think of is Symantec's BackupExec software.Thu, 01 Nov 2012 07:34:02 GMTScott D. Jacobsonhttp://www.sqlservercentral.com/Forums/Topic1379760-324-1.aspxA fair number of applications will install SQL Express as their data backend. Mainly if you have third party .NET apps installed. I've seen that a fair number of times.Thu, 01 Nov 2012 06:17:18 GMTGSquaredhttp://www.sqlservercentral.com/Forums/Topic1379760-324-1.aspxWe're in the middle of a security audit at my place of work and we have unearthed a lot of SQL express installations (different versions). I know that a Visual Studio installation can also install SQL Express - but not all of the PCs have Visual studio installed.Some of the users have had the PCs from new and claim that they haven't installed it.Does anyone know how to determine what has installed it - or am I asking for the impossible and have to compare installed software on all the PCs to try to find a common element?Thanks in advanceThu, 01 Nov 2012 05:54:30 GMTStuart Davies
