You can see this information easily throughput
Control Panel – > System and Security – > System – > Look out “Computer name, domain and workgroup settings”

Since, its domain information, I am not providing the screenshot, you may try it out yourself and share your thoughts.
I’d like to grow my readership. If you enjoyed this blog post, please share it with your friends!
