SYMPTOMS
When a user's environment is mixed with Microsoft Windows NT 4.0 BDCs and Windows 2000 DCs while the LmCompatibilityLevel registry entry is in use for higher security, the home directory drive connection may not appear on the Windows 2000 Professional client computer. This problem may occur in the following environment:
 * The DC must be a Windows 2000-based DC, and the user's home directories must be located on a Windows NT 4.0-based BDC.
 * An LmCompatibilityLevel setting of three must exist on the client, and a minimum setting of three must exist on the servers.



CAUSE
This problem can occur if the client redirector code is passing two credentials, and the second one does not include the domain name.
