Question : DC List test failed - Failed to enumerate DC's by using the browser.  [ERROR_BAD_NETPATH]

When I net a NETDIAG, it shows that DC List test failed.  I've run netdiag /fix with no joy.  Please tell me how to fix this error.

Thank you for the explanation on the reason to close the question. It helps if you do post the reasons as our (experts) nature is to help and when we have failed (by someone wanting a question closed rather than accepting an answer) we like to know why.

Anyway...

You shouldn't need a reverse lookup zone to resolve this particular problem, but I usually create one on networks that I build - it keeps the DNS config nice and tidy.

In this particular case this is what I would do.
1. If the machine is currently part of a domain, or appears to be, then drop it in to a workgroup. Reboot.
2. When the machine comes back, change its name. Reboot.
3. On the domain flush out entries for the old machine name. Disable the machine account then disable.
Do the same in DNS and WINS.
4. On the workstation, verify that the DNS is pointing to the domain controller. If you are using WINS as well then this needs to be checked as well.
5. Attempt to join the domain.
Don't use the wizard, just right click on "My Computer" and choose Properties. Then click on "Computer Name". Click the button "Change". Adjust the option to be a member of the domain and type the domain name. Press enter and you should be prompted for credentials. Enter a domain admins credentials - username and password. You don't need to enter the domain name anywhere.
Apply/OK out and reboot when prompted.
