How we can redirect specific user’s subnet to get the authentication from particular AD site

You can redirect a specific subnet to authenticate from a particular Active Directory site by using site link bridges and connection objects. Here are the basic steps:

1. Create the subnet in Active Directory Sites and Services, if it does not already exist.
2. Create a site link bridge object that links the subnet’s site to the site containing the domain controller you want to authenticate from.
3. Create a connection object for the specific user or group you want to redirect. Specify the following:
4. Username or group name
5. Source (the subnet)
6. Destination (the site containing the domain controller)
7. Cost (a number determining the preferred site)
8. Configure the cost for the connection object to be lower than the default site link cost. This will make the destination site preferred.
9. Disable the normal site link between the source and destination sites. This forces authentication traffic to use the connection object.
10. The user or group will now authenticate from the domain controller in the destination site you specified in the connection object, rather than a default domain controller.

So in summary, by creating:

• A site link bridge to allow authentication traffic between the sites
• A connection object specifying the source subnet, destination site, and cost
• A lower cost for the connection object
• Disabling the default site link

You can effectively redirect authentication for a specific user or group from one subnet to a domain controller in a different Active Directory site. This allows you to optimize authentication performance for certain users.

Hope this helps! Let me know if you have any other questions about redirecting AD authentication using subnets.
