A domain is a type of network where user accounts, computers, and other resources are centrally managed by servers called domain controllers. In contrast, a workgroup is a peer-to-peer network model where each computer is managed independently, and there is no central authority.
How do you handle a server that is running out of disk space?
When a server is running out of disk space, I first identify large files or folders using disk analysis tools. I then clean up unnecessary files, move data to other storage, or expand the disk if possible. Regular monitoring and alerts help prevent this issue from recurring.
