In order for the MinCoin client to support more connections you might have to create an ini file in the %appdata%\mincoinfolder. To get to this folder click your start button (start->run for Windows XP) and type in %appdata%\mincoin
Now right click in the folder (not on a file or directory) and goto New->Text Document
Rename it to mincoin.conf
Now you should get this pop-up as you’re trying to change the extension of a .txt file to .conf. Click Yes.
If you don’t get the above pop-up you’ll have to switch off “Hide extensions for known file types”. In Vista/Windows7 you can find this by pressing ALT once and then going to the Tools->Folder options menu. In Windows XP this menu should be visible without pressing ALT.
After this, remove the .txt from the filename so the full name becomes mincoin.conf.
Now open mincoin.conf and insert this information:
Click "File" then "Save" then exit.
*Shouldn't really be a "need" for this ^ now with the latest client (mincoin-qt-v6.0.5.zip ) but I think we can keep this as a mini reference guide.
