This old laptop serves as my Active Directory Domain Controller, it runs Zentyal Linux (Ubuntu).
Almost all of my modern PCs authenticate to it as their primary domain controller. It also serves DHCP/DNS/PXE/TFTP for my Network OS Deployment server, and some minimal network storage (most of the network storage is handled by my FreeNAS).
