Hello,
Initially looks like your Windows 11 Enterprise device is configured to prompt for credentials when connecting to a network. This is a security feature that is designed to protect your device and network from unauthorized access.
To stop the prompt from appearing, you can try the following steps:
Go to the Windows Settings app and navigate to "Accounts" > "Access work or school"
Under "Connected to," you should see the option "Connect to a specific network." Select this option and enter your credentials for the network you are trying to connect to.
Click "Connect"
By providing your credentials in this way, you should be able to avoid the prompt appearing in the future.
Other possibility, if the computer doesn't have the same issue when connecting without the docking station, is that the docking station is not compatible with some Network Authentication Level implemented in your company (perhaps it has some firmware that can be configured too?), you are using DHCP for IP assignment, so the policies require a proper logon to connect.
