  That's good.

  That doesn't really matter.

  Which is what you said before.

  There are many tools to do this.    The server comes with a program called "smbencrypt" that does this.

  It isn't the issue.  As I explained before.

  You've said that before...

  That's fine.

  2.2.26 is many years out of date.

  As for the rest of the debug output, you're *proxying* the packets to localhost:

  Don't do that.  I said create a *local* realm.  The comments in the proxy.conf file tell you how to do this.

  Just do: {

  And it should work.

  And PLEASE edit your posts.  There's no need to include 100's of lines of prior messages at the bottom of your post.  Follow best practices and you can get problems solved.  Have poor practices, and you'll be stumbling in the dark for a long time.
