I hear you on that! File sharing turned a little hairy with 10.9 on a few fronts. Most of the other issues were taken care of by 10.9.4 (10.9.2 and 10.9.3 took care of a lot of the AFP and WebDAV issues, thankfully!), but that SMB2 vs SMB on Windows thing looks like one of their sticky ones.
The issue between SMB2 and SMB on Windows 2008R2 is one we've been looking into for some time, since it's had a pretty negative effect on Casper Admin and its ability to not only compile configurations but to even mount Windows based distribution points entirely. Not a fun situation for anyone.
I'd love for something new to come up as well, from a JAMF point and just in general, as we're very aware that this is a pretty inconvenient problem for customers who are in a heavy Windows environment or who have a Windows SMB share as their primary distribution point. It's pretty frustrating for customers and for support (believe me, nobody here likes having to say 'it's a third party issue and we don't really have a good/easy way around it yet'!) and there doesn't yet seem to be a good way to get around it effectively. If there is, I've just been super unlucky in finding it.
The defect we have open is actively being worked on. I had a chat with one of our developers about it yesterday, though it was more confirming what was being seen and asking about some of the workarounds found on Apple's Forums and with the blog post mentioned. I'd guess they're hoping to avoid having to slow things down to use the older SMB protocol, which isn't a bad thing to want to avoid.
We do watch the Apple discussion forums as well, and it looks like it's a pretty widespread thing when Windows servers are involved (from what I'm seeing, at least where the JSS is involved, it appears that it's still working mostly okay with Linux SMB shares). It would be nice to see some more compatibility built in on the Mavericks side of things, or at least an update to get some better backwards compatibility going, but we may be stuck with the workarounds until that happens.
If you don't mind sharing, what did you see in terms of behavior when trying some of those workarounds? On my test machines, I saw a slight improvement and one share point that was unable to be mounted in Casper Admin would finally mount, but it was still pretty slow transferring data, and I still couldn't compile configurations.
I've got this thread (and the other one) bookmarked to watch for updates, and if I manage to dig up anything new/different, it'll certainly be posted.
