I am having the same problem, in a slightly different context. I will describe my situation and what I have tried in as much detail as I can in the hope that it helps others (and myself) in tracking down the cause of the 10053 in my specific case.

First of all I dont IRC much in the sense that I chat or do DCC. I just go to one specific channel on one server almost every day to meet up with opponents for an online game. ( #magic-league on irc.quicknet.nl , in this case).

Now I normally do not use Mirc. The site for my game (www.magic-league.com) runs an applet that is basically an IRC client /front-end. I usually use that and from time to time Mirc 6.03. I have been happily using this site for nearly a year, on windows 98, without any issues. A few weeks ago I switched to a new PC with windows XP Home, making the old 98 box my backup machine.

The first two weeks of using the new PC all was fine. Then I started getting connection drops in the applet, though my other internet connections (eg email) worked ok. When these drops started to get more frequent I switched to using Mirc for better error-analysis. Hence I discovered the 10053 error messages. The problem is getting progressively worse, with conn drops getting ever more frequent, and not beeing identifiably triggered by any event. It is now at the point where I can barely log onto the IRC server, with the connection often hanging before I even see the complete Message of the Day (MOTD). Also, in the past a logon to the point where you get your command prompt (after the MOTD) would take about 2 seconds, it now takes up to 2 minutes.

Things I have tried: disabling the XP firewall did not help. I have recently replaced it with Norton Internet Security 2003, which prompted me on the first Mirc use and made the appropriate rules. Uninstalling Mirc 6.03 and installing Mirc 5.9 did not solve the problem. I doubt even using a different IRC client would help, though I havent tried that yet. So far it looked like a problem with the TCP/IP stack and sockets in XP.

However...yesterday, after the umpteenth 10053 connection loss on XP, I walked over to the old 98 box, (networked with XP using Internet Connection Sharing, cable modem) and fired up first the site with the applet, then Mirc, both times being confronted by 10053 conn losses immediately....on windows 98 ! On a machine that never had that problem before !
Weird eh ?

One more thing I will try is the connecting with the hard IP address on port 7000, hoping my IRC server does listen on that port.

Hopefully my info helps you experts to track things down, and I'll be happy to supply any other information you request.

Cheers,
FD

Edit:
I have also tried disabling all firewalls altogether (perhaps port 113 was blocked) but that didnt help either.
On a sidenote, since the forum says my post here was the most recent one (for the moment), why doesnt this thread jump back to the top of page 1 ? How else will you guys find out I added onto this thread ? ( confused
