JOb running SSIS package

I have an issue when a job is scheduled to run a SSIS package. The package (exporte a table to a text file) runs fine from microsoft visual studio but when i create a job and run it, i get the following error:

[298] SQLServer Error: 15404, Could not obtain information about Windows NT group/user 'VOLCANO\Administrator', error code 0x534. [SQLSTATE 42000] (ConnIsLoginSysAdmin)

Can you tell me what operating system you have? Windows 2000, Windows 2003?

Thanks

This forum (and the error above) is for SQL Server Integration Services - is your question related to that?
