Data type Range Default value
REG_DWORD 0 | 1 1


Stores the user setting for the domain controller message. (The computer setting is stored in the value of ReportControllerMissing.)

This entry determines, in part, whether the system displays the following message when it cannot contact the domain controller that stores a user's roaming user profile.

A domain controller for your domain could not be contacted. You have been logged on using cached account information. Changes made to your profile since you last logged on might not be available.

This entry stores the setting of the Do not display this message again check box on the domain controller message dialog box. When you select the checkbox, the system sets the value of this entry to 0.

Value Meaning
0 Do not display the domain controller message. (The check box is selected.)
1 (or not in registry) Display the domain controller message. (The check box is cleared.)

Display of the domain controller message is managed by two registry entries, ReportDC and ReportControllerMissing. The message is displayed only when both entries are set to their display setting, that is, when ReportDC is set to 1 or it does not appear in the registry, and ReportDomainController appears in the registry with a value of TRUE. By default, the message is not displayed.

Note Image Note

While the domain controller message is displayed, other elements of the user interface are disabled, but all processes continue to run normally. If the OK button accompanying this message is not clicked after two minutes, the message box disappears.
