DFS disabled on Windows 7

DFS (Distributed File System) not working on Avid Windows 7 PC’s. I had gotten a call from one of our editorial support techs. They were deploying Windows 7 PC’s on the domain with the Avid editing software.  They were not able to connect to DFS shares on the domain. This is the error they would try and connect to a DFS, “An unexpected network error has occurred.”   DFS has been working fine on our PC’s which use the same hardware as they did.  HP Z800’s the only difference is they had a PCI-E Controller for the Avid hardware.

The PC had the Avid Unity MediaNetwork client software installed. After checking online, it turns out the Avid Unity software disables DFS on Windows 7 by default. Here’s the PDF were I found out about this on page 17.

I was able to fix this remotely. I ran computer management from the Administrative Tools in the control panel | services | turned on Remote Registry.

I then ran regedit from Start | Run | regedit | File |  Connect Network Registry

I then just browsed to


and right click on DisableDfs entry and select modify.

Type 0 in the Value data text box to enable DFS or Type 1 to disable it.
