My old PC (XP Pro) was connected to LAN1 on my router, which was connected to my cable modem. No problem.
Built a new computer (also XP Pro), and connected it to LAN2 on my router. With a little work, I was able to map to the C drive on my old computer, so that I could transfer files. So far, so good.
Then, I switched the two computers. Old computer now in LAN2, new computer in LAN1. I reconfigured my router so that the DHCP reservation points to the new computer's IP. Under Dynamic DHCP Clients, I have my old computer's IP. I have powered down both computers, restarted the router and cable modem.
The problem: I can no longer map new PC to old PC. I've made sure that both use the same workgroup name. If I open up Microsoft Windows Network on my new PC, I see... my new PC, along with a shared folder from the new PC. Meanwhile, the old PC can map to a shared folder on the new PC. So, basically, everything is backwards now: instead of mapping new to old, I can only map old to new.
If I try to map to the old PC's IP address, it times out. Can't ping it, either. However, using the router's control panel, I can ping the old computer successfully.
What did I mess up?
