Remote Boot Response Time

  • Article

The Remote Boot service can be configured to respond to a Preboot eXecution Environment (PXE) request immediately, or respond to requests, specified in seconds, that are at least n seconds old by setting the Remote Boot manager Response time field. When a PXE client device sends a request to the Remote Boot service, that request has a time stamp generated by the client device. The time stamp is a relative value, usually time elapsed since boot. When the Remote Boot service receives the request, it compares this value to the response time value and processes the request accordingly.

If the response time is set to 0, and the initial request from the PXE client has a time stamp of 4 seconds since boot, the Remote Boot service will respond to the initial request. If the response time is set to 5, the Remote Boot service does not respond to the initial request but responds when the client is retried. You can configure the response time with the following settings:

  • Users who want the Remote Boot service to respond to request immediately should set the response time to 0.
  • Users who want to respond only to client retries can increase the response time to a maximum of 32 seconds. Start with a delay response of 5-9 seconds and adjust accordingly.

Due to server configuration and variance in the implementations of the PXE clients, you should thoroughly test these settings.
