Ok, I think I fixed the DNS problem. I was running avahi, and apparently 
you can't use avahi and also have a DNS server with a domain ending in 
.local. Shutting down avahi fixed it, although if I wanted to keep avahi 
working I could probably fix this by changing my domain to end in 
something other than .local.

But now the mount command hangs and never returns. I get this in 
/var/log/syslog:

I might be missing something, but none of these entries look like 
errors. Where else should I look?
