Corina, I'm a consultant. This means my work environment often changes. 
It also means that I do not have as much clout to tell a fortune 500 
company to change their configurations just to make little ole' me 
happy. So I have to make do with what I have on hand. Having nfs-client 
in Cygwin might be one additional tool that I can control directly. Then 
again, the nfs-client may not have solved this problem anyway. I'm not 
sure.

Thanks for some of these pointers. I'll pass them around. But it's my 
understanding that the remote file server is a Netapp, not a Windows 
box. Also, I don't have Win 7. I have plain old XP. It's common.

I don't think there's an MMC snap-in on a Netapp...

As I said, I don't have Win 7 - just XP. I had uninstalled SFU because I 
saw no way to solve this problem. Perhaps some of your settings above 
are transferable to the Netapp and they will set them and then I can try 
again.

I admit that NFS client is involved, a driver, in the kernel, etc. But 
isn't there SFU already coded? I guess the source isn't readily 
available if at all. I think that having an NFS client would be 
beneficial to all as NFS protocol seems to be way faster than SMB and 
more conducive to the "Linux/Cygwin" environment.

Accept that some days you're the pigeon, and some days you're the statue.
