Like many large-scale and collaborative operations, we have need of replicated common file-stores. The method we'd been using was fine from a collaborative standpoint, but not so good from a replication standpoint. So, the onwer of the repository opted to move the repository to a new server so that a replication solution could be used.
Unfortunately, the default security settings on the new server made it so the share wasn't usable from Linux clients or from Windows clients not joined to the same domain as the share server. I found the fix and wrote up a page on the subject. But still: I really shouldn't have to bust out regedit (and reboot) just to mount a CIFS export.
