We've started adding Windows 7 x64 machines to our network. They are all running 4.2.71, are in the same ERAS group along with the Windows XP x86 machines, using the same policy. The scan profile is set to scan Operating memory, Hard Drives, Hard Drive boot sectors, Removable Media, Removable Media boot sectors. Only a few of the Win 7 x64 machines have optical drives, but the majority do not. When the scan runs on the machines with the optical drives, the scan runs as expected. The scan targets are listed as something like the following, and scanned files runs anywhere from ~90k to ~400k files. Code: Operating memory;D:\Boot sector;E:\Boot sector;D:\;E:\;C:\Boot sector;C:\ When the scan runs on the machines without optical drives, it's much different. The scan targets resembles the following line, and scanned files is either 75, 82, or 165 for every machine, with the majority reporting 75 files scanned. Code: Operating memory;;;C:\Boot sector;C:\ Has anyone run into this or found a work-around/fix? I find it hard to believe that the scanner chokes and fails when there are no removable media devices found. For some machines, the existence of removable media could change daily, so grouping them based on removable media isn't an option.
