Microsoft Knowledge Base Article 816493 contains the following summary:
This article describes how to configure the File Replication Service (FRS) to permit fewer sharing violations that block replication. The Install Override feature permits FRS to override sharing violations on file installs. This article describes how to use the File Replication Service Flags command-line script tool (FrsFlags.vbs) to configure the Install Override feature of FRS in Windows Server 2003.
FrsFlags.vbs is included in the Windows Server 2003 Resource Kit Tools. Use this tool to set or clear the FrsFlags attribute for replica objects in Active Directory. The FrsFlags attribute on a replica set determines whether the Install Override is enabled or disabled. Set the FrsFlags attribute to turn on the Install Override feature. Clear the FrsFlags attribute to turn off the Install Override feature.
