SYMPTOMS
Changing a workstation or server from one domain to another in the Network tool in Control Panel and then waiting more than 10 minutes to reboot can cause the following error message when you log in to the new domain:

The system cannot log you on to this domain because the system's computer account in its primary domain is missing or the password on that account is incorrect.



CAUSE
The Netlogon service runs a scavenger thread every 10 minutes. One of the functions of this thread is to reset the machine account password if the thread discovers that it is the default password. When this occurs, Netlogon changes the password on the domain controller with which it currently has the secure channel. Because the computer has not been rebooted yet, the password is changed through the initial domain. When the computer is finally rebooted, it attempts to use the password that it established with the initial domain. This does not succeed because this password is not accepted by the new domain.



RESOLUTION
To avoid this problem, reboot the computer as soon as possible.



MORE INFORMATION
This is only an issue when you switch from one domain to another. Switching from a workgroup to a domain does not cause this behavior because the Netlogon service does not run while a computer is a member of a workgroup.

The password is reset as soon as possible to prevent another computer from using an account that has a well-known password.
