Event ID 14550 — Trusted Domain Information Status

Applies To: Windows Server 2008 R2

The Distributed File System (DFS) service initializes trusted domain information so that client computers can access trusted domains. If DFS namespace is not able to initialize trusted domain information, DFS client computers will not be able to access trusted domains. For more information, see How DFS Works (https://go.microsoft.com/fwlink/?LinkId=147277).

Event Details

Product: Windows Operating System
ID: 14550
Source: Microsoft-Windows-DfsSvc
Version: 6.0
Symbolic Name: DFS_ERROR_CROSS_FOREST_TRUST_INFO_FAILED
Message: The DFS Namespace service could not initialize cross forest trust information on this domain controller, but it will periodically retry the operation. The return code is in the record data.

Resolve

Ensure that the Dfs service can initialize the trusted domain information

When the DFS service on the domain controller cannot initialize trusted domain information, Event ID 14548 is logged if an immediate trusted domain cannot be initialized and Event ID 14550 is logged if a cross-forest trusted domain cannot be initialized. The DFS service retries the operation every hour until it is successful. To enforce initialization, you can restart the DFS service.

Membership in Domain Admins, or equivalent, is the minimum required to perform the following procedure.  Review details about default group memberships at https://go.microsoft.com/fwlink/?LinkID=150761. Perform the procedure on the domain controller that logs Event IDs 14548 or 14550.

To restart the Dfs service:

  1. Open a command prompt as an administrator. To open a command prompt as an administrator, click Start. In Start Search, type Command Prompt. At the top of the Start menu, right-click Command Prompt, and then click Run as administrator. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
  2. Restart the Dfs service. To start the service, type net stop dfs & net start dfs, and then press ENTER.

Open Event Viewer, and review the events that are logged. If Event ID 14549 is logged, Event ID 14548 was resolved. If Event ID 14551 is logged, Event ID 14550 was resolved.

If the DFS issue persists, there is probably a networking issue. The issue should be identified by other events in the System log, and resolution steps should be available in those events.

Verify

Generate a list of the trusted domains from a domain controller and from a DFS client computer. Compare the two lists to ensure that they match.

Membership in Domain Admins, or equivalent, is the minimum required to perform the following procedure. Review details about default group memberships at https://go.microsoft.com/fwlink/?LinkID=150761. Perform the procedure on a domain controller in your domain.

To generate a list of trusted domains from a domain controller:

  1. Open a command prompt as an administrator. To open a command prompt as an administrator, click Start. In Start Search, type Command Prompt. At the top of the Start menu, right-click Command Prompt, and then click Run as administrator. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
  2. Run the command nltest /domain_trusts > domaintrusts.txt to produce a text file that lists all the trusted domain names.
  3. Open the list in a text editor. For example, to open the file in Notepad, run the command notepad domaintrustlist.txt.

Membership in Domain Users, or equivalent, is the minimum required to perform the following procedure. Review details about default group memberships at https://go.microsoft.com/fwlink/?LinkID=150761. Perform the procedure on a domain controller in your domain.

To generate a list of trusted domains from a DFS client computer:

  1. Open a command prompt. To open a command prompt, click Start. In Start Search, type cmd, and then press ENTER.
  2. Run the command dfsutil /spcinfo > domaintrusts.txt to produce a text file that lists all the trusted domain names.
  3. Open the list in a text editor. For example, to open the file in Notepad, run the command notepad domaintrustlist.txt.

Compare the list of trusted domains from the domain controller and from the DFS client computer to ensure that the lists match to confirm that the Dfs service is working properly.
