When I run a patch scan on our entire network or domain, not all of our computers are being recognized.
More detail: When scanning, I watch the Shavlik Protect Operations Monitor, and on Step 3 (Resolve machines to scan), it shows Attempted: 160; Resolved: 95, Failed: 65. When I look at the results and sort them by Machine, I can see some obvious exclusions.
Why are some machines completely unreachable and unlisted in the results, while some are unreachable, but provide error codes?
