Can anyone comment on the bug issues with DFS versus UNC?

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!
