We have a WAN site say site_A where the workstations are all domain joined and AD authentication works fine as well as other AD services, but we have a login script that relies on the Site to determine drive mappings etc and the site is showing as the main AD Site where the domain controllers are located.
So these workstations are no resolved the AD site correctly. When running gpresult, we can see the site is returned is not the actual AD site. Other WAN sites 40+ correctly detect Site name.
I have checked and rechecked the Site ip settings etc in AD Sites and services and it appears correct.
There is a leased AT&T private cloud we use for our WAN connectivity
This one site we are seeing this issue is unique in that it uses a Point to point T1 from site_A to site_B (a bigger site close by) and site_a's traffic is routed layer2 to the WAN back to our mainsite.
Any ideas on the best way to troubleshoot? We could do a net trace if we know what to look for etc.
