--- Comment #7 from H. Verbeet hverbeet@gmail.com 2007-09-17 14:36:44 --- So the component should probably be wine-crypt32. Also, pbsvc (http://www.evenbalance.com/downloads/pbsvc/pbsvc.exe) is probably more convenient to test with than going into a server and waiting to be kicked.
IIRC when Stefan and me briefly looked at PB some time ago Stefan was able to get the verification part to work by adding half of IE6, but at that point you've got an amount of native dlls and registry entries that it's not particularly useful for anything anymore.
