Windows 2000 Does Not Support Windows NT 4.0 Directory Replication (LMRepl)

• Microsoft Windows 2000 Advanced Server
• Microsoft Windows 2000 Server

SUMMARY

You can configure Microsoft Windows NT 4.0 and earlier to synchronize the contents of the Netlogon shares on each of the domain controllers (DCs) in a domain. This functionality is called LanMan Directory Replication (LMRepl). Windows 2000 is not backwards compatible with this functionality. It has been replaced with the File Replicator service (FRS). FRS and LanMan Directory Replication cannot be configured to replicate or synchronize with each other. In a Mixed-mode environment, you may need to keep data synchronized between new Windows 2000-based DCs and the remaining down-level DCs. A Microsoft Windows 2000 Resource Kit utility named Lbridge.cmd is available to perform this function.

MORE INFORMATION

Lbridge.cmd is a script that pushes files from the system volume (Sysvol) on a Windows 2000-based server to the Export folder on a down-level server. By default, this script uses Xcopy to copy the files, or you can configure it to use Robocopy. Microsoft recommends that you schedule the script to run every two hours on a Windows 2000-based DC.

The primary domain controller (PDC) in a Windows NT 4.0-based domain is often configured to be the Export server for LMRepl. Before you upgrade the PDC to a Windows 2000-based DC, configure the LMRepl export function on a backup domain controller (BDC) and remove it from the PDC. The PDC is the first domain controller to be upgraded to Windows 2000. The Lbridge.cmd utility copies the data from the new Windows 2000-based DC's Sysvol folder to the Export folder on the BDC configured with LMRepl. The BDC then replicates this data to the other down-level DCs in the domain.
