So, I never got it to work.

The windows nfs client for Windows 7 interferes with a load of windows 
remote networking stuff. I tried it on NFS 3 & 4 servers. I tried with 
all the registry hacks for Anonymous UID & GID settings. I installed 3 
of Microsofts "Hotfix" packs for the enterprise that were supposed to 
make things better. After a week of frustration and now broken SMB 
networking I gave up and uninstalled it.

After the un-install I also had to search the registry and remove all 
references to 'nfs41' to get SMB networking working correctly as it 
interferes with network search orders.

I then upgraded the Debian server to Samba 4 using the backports 
packages. That worked out of the box and didn't require any 
configuration changes, but it didn't solve the problem.

A couple more 'hotfixes' and some registry tweaks later and no 
improvement. If I changed the file on the Linux Server, can ran 'type 
file.name' in a command window on the Windows client I could see the 
contents were still not updating for a minute or so.

Fast forward another day or so and we arrive at oplocks. Disable oplocks 
in the share in question (in the smb.conf file) and the problem has gone 
away.

It wasn't a problem for XP or Server 2003, and I tried restricting the 
protocol samba supported back to those versions, but there is something 
that has changed about the way Windows 7 manages oplocks that broke things.
