Samba as a PDC

[Murugs]

I have a redhat linux 7.1 with samba 2.2.0 installed.
I have managed to share files in the linux box with other NT workstations in the Network thru samba.
I decided to try the PDC stuff.
In the NT machine when I go to the Network Neighbourhood and enter my domain name and press ok, I get a error message "You already have a connection to the domain. You must disconnect before joining the domain"
where I am going wrong.?

Adding to my previous message I disconnected my Linux mapped shares and now the error message is
"Unable to connect to the domain controller for this domain.Have your administartor check your computer account on the domain".
