I have schduled backup of transaction log task but encountered the
following error message:

An application error has occurred and an application
error log is being generated.
SQLMAINT.exe
Exception:access violation(0xc0000005),Address:0x77e78bf4

In schedule the command box:
SQLMAINT.EXE -D -CKDB -CKAI -BkUpLog
C:\MSSQL\BACKUP -BKUpMedia Disk -Rpt
C:\MSSQL\LOG\wms_maint.rpt

(Note: Environment is WIN NT 4 & SQL Server 6.5)
Any help please, or any other better backup procedures? Thanks.
