Hello ThereSystem AdministratorCommented:
Check your DNS servers (primary and secondary)! Verify if your DNS path to your domain controller is valid.

Also check if you use roaming profiles or offline files.

I'd suggest to recreate this account in AD if everything above is OK.
Does the user use VPN or so?
bongetsIT ManagerAuthor Commented:
Hi, user is not using VPN or so... will re-creating the account delete all the files in his profile?
Hello ThereSystem AdministratorCommented:
First, check which DNS server is set as 'primary'.
If you want to recreate an account, go to Active Directory and delete the account. On the computer, go to Computer Properties -> Change Settings -> Advanced Tab -> User Profile (Settings) - delete the profile. Restart the computer for sure and log in with a new account.

But usually this is caused by badly configured DNS.

All client DNS entries must be domain DNS servers. If you want a forwarding DNS, add it to the DNS server forwarding list.
Do not delete the user account.  When you recreate it, it will have a new SID

Can you try logging on locally? Does that take a long time?

What DNS servers do you have configured locally on the windows 10 clients?


Hope this helps!
Peter HutchisonSenior Network Systems SpecialistCommented:
Check what group policies are applied to the user? Is any drive mappings and printers setup as part of it. If it is trying to connect to a non-existent share or printer, this could slow it down.
If your profiles leverage DFS links, double check the user is using the local DFS Link.

Hi Ajit Singh,  If not connected to the network then it can login without any problem.  This only happens to one specific user..
Hello ThereSystem AdministratorCommented:
What is the difference between this specific user and ordinary user? Policies? Drives mapping?

Please check antivirus activity if there isn't virus scans running at that time.
I would also suggest unticking IPv6 if your network uses IPv4 to see if this solves the problem.
Run Disk Cleanup and delete all.
Open MSConfig as administrator and deny everything on Startup.

Helpful posts from another discussion:
Are you using any folder redirection / mapping profiles to network share group policies?  This can greatly slow down the logon if you're processing a large profile.
If you don't know, open a command prompt and type in "RSOP" and wait for the report to show on your screen.  Browse down ot user configuration/windows settings/folder redirection and if you see anything there, there's your culprit.

Check the latency from the authenticated server and To ensure the best user experience, enable the Always wait for the network at computer startup and logon policy setting. This setting is in the Computer Configuration\Administrative Templates\System\Logon node of the Group Policy Object Editor.
enable do not detect slow connection- If you enable this policy, the system does not detect slow connections or recognize any connections as being slow. As a result, the system does not respond to slow connections to user profiles and it ignores the policies that tell the system how to respond to a slow connection.
