How to configure multiple Vlan in single domain and in multiple sites

Hi,

We have in process to setup our new office. Right now we have one site which having one domain i.e test.lan in default site. Now we created another member domain server in our new office in a new site i.e. site2. In Site2, we have created 3 different VLans. Both office having different IP subnets which i have configured in AD sites and services. But some users from site 2 are still logging on to default site. So they cannnot authenticate local firewall and which will create the internet  issues.

Is it required to add multiple subnet for multiple Vlans in a single sites? Because i m facing this issue with only VLan2 and 3, not with Vlan1.

Please help.

Ensure each site has a DC which is also GC.   Ensure you have assigned the respective IP subsets for each site to the correct ones.

Yes, if you have multiple VLANs at a site and there are multiple IP subnets associated with those VLANs, you'll need to create the corresponding subnet objects in AD Sites and Services and bind them to the site. Otherwise, machines on those subnets have no way to tell which DCs they should use for authentication, so they'll often use a DC at another site.
