Hello,
Thank you for posting in Q&A forum.
The problems encountered by many domain users in your organization when trying to log on to accounts outside the domain can be summarized in the following possible causes and corresponding recommendations:
1.networking issues:
Make sure that the user's DNS configuration is correct and that the network is smooth with the domain control network. You can use the ipconfig /all command to see if the DNS configuration is correct, and Ping AD domain control IP and ping the domain name to check if the network is smooth.
There may be latency or instability in the home network that prevents a timely response to a login request. After disconnecting from the home network, an alternative, more stable network connection may have been used and therefore a successful login was possible.
2.Time synchronization issues:
Ensure that the client time is synchronized with the domain control time. If the time difference is more than 5 minutes, it may cause login problems.
3.Account Status:
Check the account status of the user to ensure that it has not been disabled or deleted.
Check that the account is in the Administrators group or has permission to log on to accounts outside the domain.
4.Caching Issues:
In some cases, login information may be cached, making it impossible to log in in certain network environments. Disconnecting the home network may have cleared this cached information, allowing users to log in.
5.Security Policy:
Check the organization's security policy to ensure that there are no settings that prevent users from logging in from specific network locations.
6.VPN/Proxy Configuration:
If users are connecting through a VPN or proxy server, make sure that these services are configured correctly and are not blocking login requests.
I hope the information above is helpful.
