hehehehe... But WinDoze works eh... and yes, I know exp is not a good way to back up my database, but it works for us - for now...

show parameter AUDIT_FILE_DEST:

audit_file_dest string D:\ORACLE\PRODUCT\10.2.0\ADMIN\SPFDB\ADUMP

show parameter AUDIT_SYS_OPERATIONS:

audit_sys_operations boolean TRUE

I have checked permissions and it is correct. Further I am administrator on the server so have complete permissions.

Any other ideas?
