Cannot browse Windows 2k3 AD shares from Ubuntu 8.04

[Jeffrey D. Greenly]

This appears to be a known issue, but nothing I've tried seems to fix
it. Here's what is wrong.

I have installed Ubuntu 8.04 on a Pentium 4 system connected to a Win
2k3 Server AD network. My laptop, running 7.10 connects and accesses the
windows shares without any complications. However, on the 8.04 machine,
I can access some computers but not the file server, and I cannot see
shared files in any shared folder. I have reverted Samba and related
files back to Gutsy, with no effect. I have tried editing smb.conf with
no effect. I have installed nfs-common, kerberos, and samba. At this
point, because network access is important for this computer, I am
thinking seriously about installing 7.10. Does anyone have any other
suggestions? My google-fu cannot seem to overcome this problem.
