Event ID 16604 — QoS Policy Update

  • Article

Applies To: Windows Server 2008

Quality of Service (QoS) policies are applied to a user or computer account by using Group Policy. The QoS policies are applied to a Group Policy object (GPO), which is then linked to an Active Directory container, such as a domain, site, or organizational unit (OU), that contains the user or computer account.

Event Details

Product: Windows Operating System
ID: 16604
Source: Tcpip
Version: 6.0
Symbolic Name: EVENT_EQOS_WARNING_MACHINE_POLICY_PROFILE_NOT_SPECIFIED
Message: A computer QoS policy "%2" does not specify a DSCP value or throttle rate. This policy will not be applied.

Resolve

Change QoS policy to meet minimum requirements

A QoS policy must adhere to the following minimum requirements; otherwise, the policy will be ignored:

  • A DSCP value or a throttle rate must be specified (only one of the two is required).
  • The policy name must contain at least a single character (it cannot be blank).
  • An application name specified in a policy must be exactly the name of the executable file or the exact file system path to the file. Files stored on a network share or network mapped drive are not supported.

You must be logged on as an administrator or belong to the Administrators group to complete this procedure.

To change any of these QoS settings:

  1. Click Start, point to All Programs, click Accessories, right-click Command Prompt, click Run as administrator, click Continue, type gpedit, and then press ENTER.
  2. In Group Policy Management Editor, click Local Computer Policy, click Windows Settings, right-click Policy-based QoS, right-click the policy you want to edit, and then click Edit existing policy.
