Hello,
It sounds like you're experiencing some network and file-related issues on Windows 11 and Windows Server 2016 Essentials after an abrupt power outage.
Regarding network issues, you might need to do the following:
- Ensure that there's no physical damage to the network adapters or the cables. If they are damaged, you may need to replace them.
- Sometimes, a power outage can cause driver issues. Update or reinstall the network drivers on these PCs to ensure they are working properly.
- Verify that the network settings on these PCs are correctly configured. Make sure they are set to obtain an IP address automatically (DHCP) and that the network profile is set to "Private" or "Work."
Regards,
Karlie
