--- Comment #6 from Louis Lenders xerox_xerox2000@yahoo.co.uk 2011-06-04 10:42:38 CDT --- Created an attachment (id=35016) --> (http://bugs.winehq.org/attachment.cgi?id=35016) return some useful fake values in NetGetJoinInformation
I think the attached patch should fix the bug; it doesn't fix the crash in SIV32.EXE though, but afiacs this is due to another bug
