Mav90 I want to thank you for sorting out my problem too - after satisfactory operation for a couple of years, I found that using dcc caused disconnect off the mirc channel, effectively locking me out of irc. Also MSN Messenger would no longer connect. So I took your advice and downloaded the winsock fix you mention above and after reboot, lo and behold, both worked again. So I think you've cracked a key issue. And I'd searched all over the internet for advice. Most people were suggesting possible problems with XP firewall or with dcc settings on mirc. I'd reloaded mirc and msn as well. As you say, I think it's an adware cleaner that I use that messed up the settings and stopped dcc and msn. Many many thanks - I really hope that someone in the know will ensure that your link is broadcast over a wider forum, because I bet this is causing many other people problems too and winsock fix may well sort it out.

regards
Paul
