hi!!

try that:

1-make a backup of your msdb db.

2-restore it on your target server with another name(be carful!!!, don't overwrite on the true msdb on sql 2005)

3-excecute that in the msdb that you've restored:

use msdb_restored

go

insert into msdb.dbo.sysdtspackages

select * from sysdtspackages a

where name in ('dts names....')

and createdate =(select max(createdate)from sysdtspackages b

where b.name in ('dts names....')

and a.name=b.name)

enjoy!!!
