Use the following to verify that it exists on the server and make sure that the integration services service is running to view via ssms
I humbly apologise. The above is incorrect. I knew you could find them in msdb, but I did not check for myself.
I have now tested and this is the wrong table for SSIS packages (perhaps for the 2000 dts packages?). Below is correct taken from Zoltán Horváth at the technet pages..(http://gallery.technet.microsoft.com/List-all-SSIS-packages-in-901addce)
SELECT PCK.name AS PackageName
,PCK.[description] AS [Description]
,FLD.foldername AS FolderName
WHEN 0 THEN 'Default client'
WHEN 1 THEN 'I/O Wizard'
WHEN 2 THEN 'DTS Designer'
WHEN 3 THEN 'Replication'
WHEN 5 THEN 'SSIS Designer'
WHEN 6 THEN 'Maintenance Plan'
ELSE 'Unknown' END AS PackageTye
,LG.name AS OwnerName
,PCK.isencrypted AS IsEncrypted
,PCK.createdate AS CreateDate
+ '.' + CONVERT(varchar(10), verminor)
+ '.' + CONVERT(varchar(10), verbuild) AS Version
,PCK.vercomments AS VersionComment
,DATALENGTH(PCK.packagedata) AS PackageSize
FROM msdb.dbo.sysssispackages AS PCK
INNER JOIN msdb.dbo.sysssispackagefolders AS FLD
ON PCK.folderid = FLD.folderid
INNER JOIN sys.syslogins AS LG
ON PCK.ownersid = LG.sid
ORDER BY PCK.name;
Every day is a school day, and don't trust anyone who tells you any different.
