Dell Inspiron 5100 (purchased used in 2005)

• 1.8Ghz Pentium 4 CPU
• 512MB RAM
• 40GB HD
• 100Mbps NIC
• CD-RW/DVD-ROM

This laptop had a long service life, my mom used it for a number of years, and then when it got too slow for daily use, it served as my AD domain controller, DNS and DHCP server up until about 2022.

I no longer run Windows machines at home, so don’t need AD, and all DNS and DHCP has been taken over by my PFSense router/firewall.
