I’ve used Nltest and Dommon tools to monitor and manage our Windows NT 4.0 network. I’ve yet to see any good tools to monitor Win2K components such as Global Catalog (GC) servers or Flexible Single Master Operation (FSMO) role holders. Any suggestions?

Dcdiag.exe—a command-line utility that tests Win2K domain controller (DC) health.

Dsastat.exe—a command-line utility that compares two directory trees or GCs and detects differences. You can use this tool to ensure that DCs and GCs are synchronized.

Replmon.exe—a GUI-based utility that tests low-level Active Directory (AD) replication status. You can use this tool to view replication topology and to force directory synchronization.

Repadmin.exe—a command-line utility that you can use to view AD replication topology, to force replication, and to modify replication topology manually.

Nltest.exe—a command-line utility that tests the status of trust-relationship links for Win2K and NT networks. You can use this tool to repair such links.

Dnscmd.exe—a command-line utility that monitors and manages Win2K DNS servers.

Test Domain Controllers—checks DC availability, validates DNS records (e.g., service resource records—SRV RRs), and binds to DC to verify AD status

List Domain Controllers—lists all DCs along with each DC's name, availability, Active Directory Service Interfaces (ADSI) scripting location, and site location

List Operations Masters—lists FSMO role holders, compares them with an internal best practices list, and recommends changes when necessary

Test Replication—performs domain replication topology checks and displays diagnostic information about replication partners

Show Domain Controller Status—provides DC status summaries, including replication errors and partners, AD site analysis, and charts that show recommended DC placement changes
