In Windows NT, if a domain controller can not be contacted, and you are not a new user of the workstation, you receive:
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 may not be available.
In Windows 2000, the message is suppressed by default.
To enable the message, you must edit the registry of each Windows 2000 member. Use Regedt32 to navigate to:
On the Edit menu, Add Value name ReportControllerMissing and set this string value (type REG_SZ) to uppercase TRUE. The default is FALSE. This enables reporting for the workstation.
To enable reporting for the users, set the ReportDC value to 1.
