It happens quite often that I cannot send files to other persons (or they can't receive). We get the error: connection refused. Sometimes, I can resume to send after switching passive DCC from on to off or vice versa. What is going on here? Why are so many people having trouble with DCC send and why does it SOMETIMES work after switching the passive DCC setting? Btw: I don't have a router and I use mirc 6.17.
