sudden problems with socket connections

I'm one of the maintainers of TNT, an IM client for Emacs.
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:
> Proc Status Buffer Tty Command
> ---- ------ ------ --- -------
> toc open (none) (none) network stream connection 5190 at toc.oscar.aol.com
...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))
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.)
