Error on executing DTS via SP

[davideart]

Hy everybody
I've one problem in executing DTS packages via Stored Procedure.

I try executing the followin' in Query Analizer:

EXEC master..xp_cmdshell 'dtsrun /S <servername> /U <username> /P <userpassword> /N <dtspackagename>  /M <dtspackagepassword>'

The previous script work properly on a certain server, but if I run it on another server (on which, of course, the DTS package is also defined) what I receive back is the followin' output:

DTSRun:  Loading... 
DTSRun:  Executing... 
DTSRun OnStart:  Copy SQL Server Objects 
DTSRun OnProgress:  Copy SQL Server Objects; Scripting objects for Transfer; PercentComplete = 0; ProgressCount = 0

Have I to reinstall the SQLDMO.dll library?
I don't know how to solve this problem, so any help will be greatly appreciated.

Thank you in advance, bye
