Networks can be fragile and spanning tree can certainly cause some of the problems. That is why one must design the spanning tree topology. When you say "one switch declares itself a server of a given protocol", I assume you mean "declares itself the root of a VLAN." The root is determined by the lowest advertised bridge ID from each switch. The bridge ID is the bridge priority plus the bridge address. Cisco switches have a default bridge priority. So then it boils down to whichever switch has the lowest bridge address becomes the root, which could be any switch anywhere in your network. The network admin should decide which switch will be the root for a given VLAN and set the bridge priority lower. And then he/she selects another switch to be a backup root and sets its priority to be lower than the default but higher than the root's priority. So you if don't manually set the root then a new switch plugged into the network could very well become the root if all the switches have a default priority and the new switch has a lower bridge address than the current root.
If this happens, you can just turn off the offender to get your root back. In STP only the root talks. If the other switches don't hear from the root in something like 20 seconds, then they'll elect a new root.
I'd have to agree. I got a DVD player from my parents for Christmas and I decided I needed decent sound to go with the picture. I did some research on the HTB-503 (audioreview.com, hometheatermag.com)
and thought this would be the best bang for my buck, considering that I didn't have a lot of bucks to spend. It has Dolby Digital and DTS decoding @ 100 watts per channel. I am pleased with it. I picked it up at Sears for $500, but you can find it cheaper online if you wish.
[Bill Lumberg voice] Ummm Yeeaah. I'm going to have to go ahead and agree with you there. Sounds alot like Milton. So if you could just go ahead move your desk down to Storage Area B, that'd be great. Mmmm 'K? Thanks alot. [/Bill Lumberg voice]
It would be more entertaining than a pager!

At work we joked around about hacking these things and putting them in our offices as emergency notifiers. So instead of getting paged, we'd get a nice little song, "The router is down dooby doo down down..." Though I imagine it would get old real quick like.
um. Yeeeaaah. I'm going to have to go ahead and disagree with you of that one. Patent for respiration? I'm just not too sure about that right now. Yeeeaaah.

Thanks for the tip. I've been wanting to add TiVo to my DTV setup but I wasn't willing to shell out the ponies for it. $99? It's as good as bought.
