While performing a scan, the Workstations and Servers are uniquely identified based on its Service Tags, Name and MAC address. So for a custom-built PC, the service tag is usually filled with some default values like “System Serial Number”, “To be filled by OEM” or some random numbers like “12345678”. This results with many machines with similar service tags. In such cases, if a scan is performed, one workstation details would be overwritten by the other.
To avoid this, you can add the service tag under Invalid Service Tag list such that, the workstations with the service tag is ignored during a scan. [ Screenshot ]
