Every so often one of the NT machines logs this when its backup fails.  The
problem occurs only occasionally but I would like to know what is causing
it.  This particular machine is using NT4SP5 TSM3.73 client backing up to an
RS6k TSM4.1 level 0.

Here is the output from the dsmerror.log
01/02/2001 00:55:14 ANS1087E Access to the specified file or directory is

01/02/2001 19:00:32 ANS1512E Scheduled event 'DAILY-NT-INCREMENTAL' failed.
Return code = 4.

I find very little documentation on explanation of return codes

Thanks for any input
