Change the port for central admin
This came up in class today and one my students Eric knew the answer off the top of his head. It was so simple I thought I would share.
Stsadm –o setadminport –port 5555
This command will change SharePoint Central Administration v3 to run on port 5555. Even cooler? Didn't take a reboot or iisreset to take effect, it just worked.
