Hi DZIERZEK Dale,
Thank you for posting in the Microsoft Community Forums.
The key point in your log is that Error: 0x54b indicates that there was a problem when attempting to access or manipulate a specified domain, specifically because the domain did not exist or could not be reached. This error usually occurs during network programming, system configuration, or when a user tries to access a network resource.
Below are some of the common causes and solutions that may lead to this error:
Common Causes
Domain name does not exist: The domain name entered may be a misspelling or the domain name has never been registered.
DNS problem: The DNS server may not be able to resolve the domain name, or the DNS settings may be incorrect.
Network Problems: The network connection may be unstable, or there may be network devices such as firewalls, routers, etc. that are blocking access to the domain name.
Domain Controller Unavailable: In an Active Directory environment, this error may also result if the domain controller cannot be accessed.
Solution
Check the domain name:
Verify that the domain name is correct.
Use the ping or nslookup command to check if the domain name resolves to an IP address.
Check DNS settings:
Make sure your DNS server settings are correct and that the DNS server is working properly.
Try changing your DNS server (for example, use Google's public DNS 8.8.8.8 and 8.8.4.4).
Check the network connection:
Make sure your device is connected to the Internet or an internal network.
Check if any firewall or router rules are blocking access to the domain.
Contact the network administrator:
If you are on a business or organizational network, contact the network administrator for assistance.
Ask if there are any specific configurations or restrictions regarding the domain.
Check Active Directory (if applicable):
Verify that the domain controller is online and accessible.
Check the replication and synchronization status of Active Directory.
Check log files:
Check the system or application log files for more detailed information about the error.
Use command-line tools:
Use command line tools such as dsquery (in an Active Directory environment) to query domain information.
Best regards
