Event error 1419 may be generated on a domain controller. This event may be generated because there may be problems with an Infrastructure Flexible Single Master Operation (FSMO) role holder performing its duties if it is also a global catalog server.

The error message in Event Viewer may be similar to the following sample:

Event ID: 1419

Event Type: Error
Event Source:   NTDS General
Event Category: Directory Access 
Event ID:       1419
Date:       1/16/2000
Time:       9:58:21 AM
User:       Everyone
Computer:       Server1

This DC is both a Global Catalog and the Infrastructure Update master. These two roles are incompatible. If another machine exists in the domain, it should be made the Infrastructure Update master. The machine CN=NTDS Settings,CN=Server4,CN=Servers,CN=West,CN=Sites,CN=Configuration,DC=PRODOM,DC=com is a good candidate for this role. If all domain controllers in this domain are Global Catalogs, then there are no Infrastructure Update tasks to complete, and this message may be ignored.


This behavior can occur if a domain controller that resides in a multiple-domain-controller domain in a multiple-domain forest holds the Infrastructure FSMO role and is also a global catalog. The error message is generated after another domain controller is installed in the domain. This is most likely to occur on the first domain controller in the forest because it holds all five FSMO roles and is also a global catalog server.


There are two ways to resolve this issue:

  • Transfer the Infrastructure FSMO role to another domain controller in the domain.
  • Enable another domain controller in the forest to be the global catalog server and disable this computer from being a global catalog server.

For information about how to transfer a FSMO role to another domain controller, see the following article in the Microsoft Knowledge Base:

For information about enabling and disabling a global catalog server, see the Windows 2000 Help.
