Hi, Carol,
Why would they always receive 4 errors in the Batch Control file when running DIC and not have had them fixed?
Error 41##'S almost always refer to corrupt data.
I suspect that, if you were to create an Adagio snapshot, they would have an error(s) in their ADSError.log.
If you run Softrak\System\ChkSys.exe on their server and email the resulting snapshot, I'll take a look at this and other things in it for you. The snapshot does not gather any of their data just information about their Adagio environment.
