Joining Domain

Okay this one has got me stumped. The client in question is XP SP1, and was previously joined to domain.com. There were a few issues with network connectivity on the client. So I removed it from the domain (which is W2k domain). Found about 18 viruses all of which were deleted or quarantined. I tried to join it back to the domain again and it propted for username and password. After which it said that "the network cannot be found".

I can ping the dc by IP address as well as name. nslookup on domain.com on client returns the dc's IP address. Netbios is running, and pinging by netbios names works as well. But still "the network cannot be found". I've tried everything I can think of, I even enabled WINS. That didn't work either. I have no idea.....it's driving me nuts.

I've tried DHCP and static IP address, still the same result. Other clients are working okay. And i've also reset the computer account.

Any Ideas?

I have also looked in the lmhost file and added the dc with it's fully qaulified domain name.

Had this one before :
Be sure : remove the computeraccout out off AD
switch the xp machine to a workgroup
than try to rejoin the domain.
If this does not work than AD hasn't actually cleared the computer name out of it's Database.
Easiest way : change the computer name of the xp machine than rejoin the domain
Hope this is helpfull

Thanks for your help, but I have already tried that. It just doesn't want to work.

Hi

As stated above:

Remove the machine from the domain and join it to 'Workgroup'. Then remove the computer account from ADUC, and recreate it.

Then, right click My Computer, click the Computer Name tab, and click the 'Change' button. This will open the Computer Name Changes dialog. Click the More button and type the DNS suffix of your domain. for example company.local or ABC.com. You will need to reboot for the change to take place.

Check the DNS settings in TCP/IP are pointing to the DC as well.

Next, try to join the domain.

Good luck

I have also tried this, and still to no avail. Everything according to the networking seems to fine, that's what is frustrating me. I tried the dns suffix and that didn't seem to work but thanks for your help.

Check for a firewall blocking most network traffic. Or, remove and reinstall TCP/IP as a virus may have rewritten parts of it. To reinstall it, go to winsock and winsock2 in the registry (be careful) and delete these. reboot

Then go to install a client protocol and browse for nettcpip.inf
reinstall and reboot, see what happens

Yes - the answer given above about winsock reminded of this. I have had a similar issue in the past where the winsock chain (the Layered Service Provider), has been broken. Download this VERY useful utility and run it, then try again.

You could delete the acount in Active Directory, however I have had this problem and what I did was reset the computer account. If that doesnt work you can always delete it from AD and then reboot your client computer and try joining it again to the domain. Try using the administrator account when joining the computer to the domain. It worked for me.
