Currently, we are trying to scan all the workstations on a network using Microsoft Baseline Security Analyzer 2.1. All the Vista Business 64-bit and SP1 machines are giving the error incomplete scan. They can use the MBSA and scan themselves as local machines but anything through the network doesn't work. I tried disabling Windows Defender, Windows Firewall, and Symantec Endpoint Protection. I also logged in as a local user and tried to get access to it and had no luck. Does anybody have any idea's on why this is occurring?
