Can anyone comment on  problems with disk reads and wirtes on network drives caused by the use of DFS? We have a problem where by the use of DFS is definitely causing file corruption. If UNCs were used instead would that possibly improve reliability

that's a tough one... i would definitely do a thorough check of integrity of the HD's in use throughout your DFS.... perhaps one is acting up... or a RAID having some issues(but surely you would see event log errors etc... )

possible scenario1:  you have 3 servers participating in DFS.... take one of them out of the loop, see if it's causing the issue... round robin....  

possible scenario2:  the machines participating in DFS are across vpns, or on different physical switches... maybe move them to diff ports... or swap out a switch....

but honestly it sounds like a failure with the physical HD's participating in DFS

Well I actually did not give you that much info. Lets try again. I was looking for a general response because so far DFS which I know uses a different redirector seems to have more delayed writes and flakes out I believe more so with windows 2003 under VMWARE.  It is not clear why the flake-out but it happens every so often and considering the file corruption problems this would be best avoided.
1st thought I had was to use UNCs instead of DFS paths but this is based on a believe that DFS is inherrently buggy especially under VMWARE.   I have also seen problems when disks were heavilly fragmented. The problems experienced are low level OS problems but why they happen or how to stop them I know not!
