Many ppl have reported probs with 10053 error, especially those using xp (and some with 2k). If you use the search feature here, set it to All Forums, and expand the date range to All, with 10053 as your search term, you can wade thru what others have tried and found successful, altho its not a one solution fits all kind of thing. For many users it appears that its winxp/firewall/router related, not mIRC or scripts, altho there can be any number of reasons behind 10053 error.
