Attempt to fix secedit.sdb yields error -1003

Dear experts,

I recently found error 1005 from source SceCli on my Windows 2003 SP2
server. The description says "Some JET database is corrupt. Run esentutl /g
to check the integrity of the security database
%%windir%%\security\Database\secedit.sdb."

Tried that, resulting in:
"Operation terminated with error -1022 (JET_errDiskIO, Disk IO error) after
0.0 s
econds."


Then I tried

C:\WINNT\security\Database>esentutl /r C:\winnt\security\database\secedit.sdb

Here is the result:
Initiating RECOVERY mode...
Logfile base name: C:\winnt\security\database\secedit.sdb
Log files: <current directory>
System files: <current directory>

Operation terminated with error -1003 (JET_errInvalidParameter, Invalid API
para
meter) after 0.0 seconds.


Can anyone please give me some coaching on how to proceed?

Thanks!
