We're running 9.5 SP1 and I've got some problematic machines out there (Windows 7 PCs) that just aren't getting their scans processed correctly. When I look in the error scans folder, sure enough, the failed scans for these PCs are in there.
I've turned on logging statistics and get the following error in the application log each time one of these machines is scanned:
Database exception: SCA4AE1.SCN, LDInv.dll
Data provider or other service returned an E_FAIL status.
Error comitting on table SERVICES: DATA PROVIDER OR OTHER SERVICE RETURNED AN E_FAIL STATUS.
Increased column size might be necessary, Thread ID: 4692.
Anyone come across this before?
