XP Pro can't join NT 4.0 domain or W2K AD

[Rinnt]

Hi,

I have a Windows XP professional client that needs to join a W2K active directory. I also have a NT 4.0 domain that I've tired to join as well. Neither work and give me the error:

&quot;A domain controller for the domain <domainname> could not be contacted. Ensure that the domain name is typed corerctly. If the name is correct, click Details for troubleshooting information.&quot;

There's things in details about DNS (which I really dont' understand - _ldap._tcp.dc_msdcs.<domain name>???????) etc. I've seen other posts and it seems like this is a common question yet w/out a common answer... Please help!!!

Rinnt,

Assuming all connections are already working and user added to W2K server, On your XP box, Right-Click My Computer->Properties->Computer Name TAB;

Click &quot;Change&quot; Command Button->Enable Member of &quot;Domain&quot; and enter <yourdomainname>. Next, Click &quot;Network ID&quot; and follow instructions. The first set of User Account/Password should be of the Administrator then the second set is the User Name/Password (XP User) to be added on the network. XP will prompt you to reboot.

Check IP address. If being handed out by DHCP ensure the client is getting an IP from the server. There are server options to give the client the preferred DNS server address as well as the default gateway.
If you are not using DHCP ensure the client has an IP address in the same subnet as the domain,the address of the DNS server, the same subnet mask as the server, and a default gateway pointing to the server(domain).

By default XP Pro will secure the data channel to NT 4.0 but NT 4.0 is not configured to do this by default.

To fix this, at XP Pro, goto

Control Panel -> Administrative Tools -> Local Security Policy

Under Local Policies, Security Options node,

doubleclick on &quot;Domain memberigitally encrypt or sign secure channel data (always)&quot;

Click 'disabled' and then 'OK'
You should be able to logon or join the domain now.
