Hi chaps, Bit of an odd one, and i'm at a loss. In work all machines by default are now setup with their name & domain joined via sysprep through OSD Example - PC658.clients.global.company.com - this is reflected in the machines name by going into it's settings. ipconfig /all shows: Primary Dns Suffix . . . . . . . : clients.global.company.com so it's all recognized as working on that suffix. However - you can't ping it by typing in ping pc658.clients.global.company.com - when you ping pc658 - it resolves to pc658.global.company.com - missing the clients bit. Any other machine outside of this subnet resolves correctly, all settings are exactly the same, which makes me wonder if there is perhaps something needing setting on the local DNS server. It seems odd cos it's registering the DNS suffix and even shows it on the client machine - yet won't resolve. I'm stuck - has anyone come across similar?
