In tip 237, I had documented the ReportDC registry value for preventing the subject message. The Resource Kit is incorrect. Here is the correct procediure: On your Windows NT 4.0 Workstation with Service Pack 3 installed, and a locally cached copy of your profile, edit:
Add Value name ReportDC as a type REG_DWORD.
A data value of 0 suppresses:
"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."
A data value of 1 does not suppress the message.
