Hello,

I've encountered this message (below) on my primary DC. I understand the underlying issue (we have subnets and devices on them that are not mapped to AD sites and services.)

During the past 4.During the past 4.23 hours there have been 730 connections to this Domain Controller from 23 hours there have been 730 connections to this Domain Controller.. ect. "NO_CLIENT_SITE"

My question is.. what is the consequence of this? What will happen if this is not resolved? I"m sorry for my ignorance and I will greatly appreciate any guidance.

This means that you have computers logging on from IP subnets that are not defined in AD Sites and Services.  This means that the computer doesn't know which domain controllers they should be using (closest) for logons, so any DC with published SRV records will be randomly chosen.

Nothing will happen. Clients will eventually find an authentication path to a domain controller (if the network is in place) and it will authenticate just like any other computer on the network. The down fall will be on the user end experience as it will be inconsistent (sometimes fast authentication and sometimes slow authentication).

Meaning the user might authenticate to a DC in close proximaty to them first and then it might authenticate next to a DC that is much futher away geographically.

Long story short is nothing will happen everything will continue to run but it will not run efficently. It is best to associate a subnet to a specific site for authentication.

Will.
