Hi Query King,

 

There are many reason for Slow Login, but as you mentioned same user login faster from different location, so I have doubt that may be your location C subnet is missing from Active Directory Site and Services.

Please check and share below details.

 

1. Run the below command on any users from Location C and check the Logon Server Name.

a) Run "nltest /sc_query:YourDomainName" on command prompt.

b) OR Run "Set L" on command prompt.

 

Once you have the Logon Server Name, for example XAAD-06. Go to Active Directory Site & Services and check if XAAD-06 is the showing under Location C site. If not then check if your user subnet is added with Location C site.

Please share the location, Site and DC details for each site. (Not Actual, only reference). It will help me to solve the issue.

 

 

Hi Santosh,

 

Thanks for you time and response.

Please find my findings. I have checked and found that my Location C users logon Server is DC-02, which is in site A, where as I have installed DC-06 for location C.

 

Please find the details as requested as suggest how to fix this issue.

 

AD Server Details:

Location AD Site Name AD in Site
Location A Site-A DC-01
Location A Site-A DC-02
Location A Site-A DC-03
Location B Site-B DC-04
Location B Site-B DC-05
Location C Site-A DC-06

Check the netlogon.log file at %systemroot%\debug\netlogon.log location . If any of subnet entry missing from adss . then you can get details of those missing subnet here.

 

And  second thing  , can you check from one workstation by running below Command

Set L 

This above command must return one of the DC details running in that AD site

 

 

 

 

As you mentioned, User is authenticating through DC-02 which is from Location A. That’s why user login is taking long time. As per your above table, you have DC-06 at Location C but there is not Site created for Location C.


Please follow the below Steps
