Problems With DTS Package. Access Denied

Hi,

I made a DTS-package and it works when I execute it manually, but when it is
run by the SQL Server Agent, it fails.

I have use the guide to create a maintenance plan. That doesn't work so good
either. It runs Optimizations, but not integrity checks or backups (probably
because integrity checks failed).

The following from the log file:
Executed as user: HT-DOMAININTRAB-SQL. ...:

DTSStep_DTSExecuteSQLTask_2 DTSRun OnFinish: DTSStep_DTSExecuteSQLTask_2
DTSRun OnStart: DTSStep_DTSExecuteSQLTask_1 DTSRun OnFinish:
DTSStep_DTSExecuteSQLTask_1 DTSRun OnStart: DTSStep_DTSDataPumpTask_1
DTSRun OnStart: DTSStep_DTSDataPumpTask_3 DTSRun OnError:
DTSStep_DTSDataPumpTask_1,

Error = -2147024891 (80070005) Error string: Access is denied.

Error string: Cannot open a log file of specified name. Access is denied.
Error source: Micr... Process Exit Code 1. The step failed.

Log-file endeth here.....

My "data-sources"/Connections is set up to use sql-server
authentication where I enter superuser name+password, not windows
authentication.

If I browse around using SQL-EM:
Under Security - Logins HT-DOMAINintrab-sql:
Tab General: Grant Access
Tab Server Roles: System Administrators
Tab Database Access: checkmark at Mbestil, user=dbo; database roles
for mbestil = public + db_owner

I also have som problems identifying where the package fails. I have given
the individual "steps"/"transformations" some pretty good names, but in the
log-file it still shows the "old" names.

The DTS package empties a table, then fills it by copying data from another
table in another database on another server.

Anyone with some useful tips ?
