Still no idea why. :) If anybody else ever has this issue, I'll tell you the steps I took to resolve it: 1) Whine on someone's well-thought-out blog post. 2) Contact someone at Microsoft for their opinion. 3) Wait a few days, but change nothing. VOILA, it's fixed. :) Joking aside, did Chris W. ever determine what permissions issue was stopping VNC server from starting? I'm in the same boat now. My slowness issue has gone away.

I've done just that, and I'm sure it will help with other areas. However it doesn't appear to have much of an affect on this particular source of NFS slowness: -bash-3.00$ time ls real 0m5.986s user 0m0.000s sys 0m0.002s -bash-3.00$ time mkdir 1111 real 0m1.494s user 0m0.000s sys 0m0.001s -bash-3.00$ time cd 1111 real 0m1.496s user 0m0.000s sys 0m0.000s One puzzling bit is that I've seen quite a few blog/forum posts about this kind of slowness, but no definitive explanation or remedy. Scott,

By default, UID is *not* indexed, and it can make a world of difference in how quickly AD responds. This is just a guess.... Hope this helps! Farris,

However, something I haven't seen addressed is annoyingly slow access to shares mounted on a linux client to a Windows host using NFS. I don't know if it's just that the MS implementation of NFS is very slow, or what. It can't be my network hardware, as it's wall-to-wall GigE, and all other protocols between these boxes are as expected. Here are some examples from within a user homedir that is mounted via NFS from my Win2003R2 file server: -bash-3.00$ time ls 1234 real 0m1.504s user 0m0.001s sys 0m0.001s -bash-3.00$ time mkdir 4321 real 0m3.021s user 0m0.000s sys 0m0.000s -bash-3.00$ time cd 4321 real 0m3.009s user 0m0.000s sys 0m0.000s Any ideas?

It's probably something like the permissions allow other users to read (at least, that's what Linux thinks) and therefore VNC won't use the password file. I know I've run into a number of issues where file permissions that were too lax caused things not to work properly. Chris W,

I do have one issue though... When an AD user logs into an AD domain member linux host the home directory automounts correctly; however, that user cannot use VNC. An input/output error is recorded and the gnome session does not start properly. I am guessing that it is a permissions issue since by moving the password file to a directory other than home solves the problem. Any thoughts? Your articles have been a great resource!

Check out the reference materials for Samba; they can give you more details on configuring smb.conf to meet your particular needs. I’m not sure I understand your question.

However, I'm fairly confident that you could whip up a shell script...er, batch file...that could help automate that process. Good luck! Mel,
