Ok, I feel really dumb now....
Luckily I got on IRC hoping to resolve this issue so I can put it behind and someone suggested I double-check my router's DCHP table. I have a local IP reserved for my Pogoplug's MAC address, so I figured that IP would not change. However, ALARM changed the mac address and therefore it got a different IP that I kept overlooking since I have several devices on my LAN. The computer name is alarm and it just blended in.
Once I entered the correct IP, it connected just fine. WOW .... there's nothing more frustrating than realizing how many hours have been wasted over something so simple. Thank you all very much for helping!
