Hi, a couple of things going on here in your post:
1. On the identification tab (on network applet -that is greyed out..
Has the laptop been added to the domain in server manager on your PDC? If not, that needs to be done.
2. For command line checking - on the laptop, you can type ipconfig /all to see if the machine gets an IP address (if you are using dhcp)and if your laptop is running workstation. ipconfig /release is the command to release an ip address and ipconfig/ renew to renew the ip address (again, assuming dhcp and laptop runs wkstn)>

I suspect, based on the information you provided, that the laptop has not been added to the pdc using server manager. Anyway, I hope this helps you.

You haven't stated whether or not you can ping the DC.
When you do the ipconfig /release are you following up with ipconfig /renew? What happens?
If you can ping the DC, are you sure that you are logged onto the Workstation as an administrator and not a power user?

1. Check the IP address and Subnet Mask. Pay very close attenton to the numbers. Make sure you are on the correct subnet and your IP is valid. If you are running DHCP and you are sure the server is setup correctly this does not apply.

2. Try toping the server by IP. Do you get a response?

3. Add the computer to the domain. (this requires the correct rights on the domain to do so.)

4. I know you tried to reinstall the NIC, but did you try to replace it??

5. I know you posted this in the NT section, but I will not just assume the laptop is NT. If it is not then the TCP/IP protocol stack may be your problem. See article Q191064 on Microsoft's TechNet.

Firstly, I would check the port is live by swapping a cable from another Pc. Next I would check that the computer name given to the laptop is not already taken. Remove from the domain, reboot and then add again. This should allow you to then add to your domain. Hope it helps.
