Dear Reed,
The "RefusePasswordChange" key can be set to 1 on DCs to disable the
machine account's change. The provided steps are aimed to ensure that your
registry entries are configured correctly. The DWORD "DiablePasswordChange"
value needs to be set "0" as well.
After the reboot, please repeat the steps I've provided in initial
response, and then test the situation. For your convenience, I've pasted
them again as below:
a. Start the Active Directory Users and Computers tool, right-click the
Domain Controllers container, and then click Properties.
b. Click the Group Policies tab, click the Default Domain Controllers
policy, and then click Edit.
c. Expand the following items in the policy:
Computer Configuration
Windows Settings
Security Settings
Local Policies
User Rights Assignment
d. Double-click "Access this computer from the network", click Add, click
Browse, and then add Everyone and Authenticated Users.
e. Click OK in each dialog box or window to quit the policy editor. Close
the domain controller properties, and then quit Active Directory Users and
Computers.
f. At a command prompt, type "secedit /refreshpolicy machine_policy
/enforce" (without the quotation marks), and then press ENTER.
Regards,
Seaver
