Tools | 'SQL Server Discovery' does not show Version, Build, SP or Edition for the discovered instances.
The 'SQL Server Discovery' runs successful for scanning by IP Range. However, when the scan is complete the Version, Build, SP and Edition columns are not populated for all instances discovered.
When running the discovery by IP address, try to un-check the 'Network Registry Connection' and 'TCP Connect' options. Once this is done and run it again, the Build, SP, and Edition fields were populated.
