sudden problems with socket connections

Hi folks, I'm one of the maintainers of TNT, an IM client for Emacs. (http://tnt.sourceforge.net) I use TNT daily on two machines, but in the last few days I am unable to establish a connection from my laptop. The connection attempt never returns an error, but nothing seems to happen. If I quit XEmacs, I see the expected process list: ...and the "active processes exist; kill them and exit anyway" question. Under the hood, we connect to AIM as follows: (setq tocstr-process (open-network-stream "toc" nil host port)) -- I'm running XEmacs 21.4 (patch 13) "Rational FORTRAN" [Lucid] (i586-pc-win32) of Sun May 25 2003 on TSUNAMI ...though I just downloaded and installed 21.4.19, and it exhibits the same problem. And TNT definitely still works fine on my desktop, which is on the same network as the laptop! However, I can telnet to toc.oscar.aol.com 5190 from the laptop just fine. I've rebooted; I've run -vanilla; I've done everything I can think of and it has no effect. And again, this machine has been super-stable and TNT has been very reliable, until a couple of days ago. Nothing has changed on this machine in that time. I know this is a weird problem description, but does anyone have any ideas what could be happening, or how I might start debugging this? (Oddly enough, I've had to move to Emacs for other reasons but I keep a copy of XEmacs running only to use TNT! Emacs never establishes a connection for me; the symptoms are very similar to this though the cause may well be completely different.)
