My be the allow logon local policy prevents you to logon through a limited user.Just a thought
Got it sorted out.
I noticed the Router was enabled to distribute addresses on DHCP. and when i restarted the client computer after adding it on to the domain, it picked address from the router which was on another subnet from what i have on the network.
That way, the client computer couldn’t get it’s DNS resolved by the server, thus prompted the error message.
Thanks for the trouble anyway.
merci . . .
