GMScan.exe is a GUI or command line multithreaded ping, name resolution, NetBIOS and WMI query utility. It's free to download and use by friends, colleagues and IT people who may find it useful.

I originally developed this tool because I needed to monitor the online status of 100,000+ machines at regular intervals throughout the day however, inconsistences in DNS meant a ping could not be relied on. The solution was to perform a NetBIOS query and reverse name lookup. Using this simple application I was able to check 100,000 machines in under 10 minutes (it also pinpointed various name resolution issues). 


This is my small contribution in response to the community of IT professionals whose free tools and scripts I have benefited from over the years.
