It's also possible I made that build against a too-new distribution. I've=20 created a new build against Debian 12, which is hopefully better, and it ha= s=20 some extra debug logging: https://f002.backblazeb2.com/file/wine-ntsync/ntsync-wine2.tar.xz Hopefully that's functional enough to test with, or at least give more a hi= nt=20 as to why it doesn't work?
