If you have Dynamic IP…
If you have dynamic IP (your IP address is different each time you log on), make sure that "On connect, always get:" in the File/Setup/Local_Info dialog is set to get the Local Host and IP Address. If these were already set to ON make sure the correct ‘local host’ name and ‘IP Address’ are found by mIRC… on some winsocks this is rather tricky… Also try the ‘Server’ method! If you have a non-compliant stack, mIRC may not be able to correctly find your local host (domain name) and IP. With dynamic IP addressing you are in trouble then !! DCC file sending and initiating a DCC Chat (contrary to file getting and accepting a DCC Chat) requires that mIRC knows your correct IP number. Even without an IP number at all, mIRC will work as far as normal chatting is concerned, but won’t allow DCC file sending or initiating a DCC Chat.
