Ahey,
Once more, thanks for everyone's continued help and suggestions, it's helped clear my head and dig deeper on some points.
Neither network nor sound cards or drivers have changed on the machine in question. Furthermore, I've attempted to install TeamSpeak on other machines in the network, and the results were exactly the same: no joy.
However, I found out several things:
1) A few of my mates around here play Company of Heroes, and about the same time TS stopped functioning, they stopped being able to play online.
2) At or around the time when things died, our router suffered a major reconfiguration, in order to increase the flexibility with which we host multiple sites. We now have several incoming IP addresses and several HTTP/SSL proxies where we used to have only one. Presumably, however, no change was made to outgoing trafic, which continues to use our main IP, and inspection of the router configuration screens and tracert reports seems to verify this.
3) Also at or around the time when things died, there was a major power surge in the area, and several pieces of computing equipment fried or started displaying extremely odd behavior, including the network card on my work machine, which consistently failed to detect the network or even report itself to the OS.
So, I now believe that either (2) or (3) above is responsible for the problem. If it's (2), it's just a matter of figuring out what it is we did to the router to break things, then fix that. If it's (3), however, then the ultimate problem is probably at the ISP level, and I may well be screwed...
So, over the next few days, we will be looking into the problem, trying to figure out exactly just what the hell is going on...
In the meantime, if everyone out there is a network equipment whiz kid, our router is a Draytek Vigor 3300v.
Again, thanks for your continued support. I'll keep everyone posted as to my progress, and hopefuly, things will be back up and running by the time I finally get my Karazhan attunement.
Cheers,
J.
