WebDAV to UCM 11g on Windows 7
By Kyle Hatlestad on Oct 11, 2010
With Windows 7 getting rolled out to more client desktops, folks are discovering a change that Microsoft has made to the OS regarding WebDAV. By default, WebDAV on Windows 7 is only supported via HTTPS (SSL for HTTP). So if your UCM instance is not running over HTTPS, then these clients would have difficulty in establishing a WebDAV connection.
But it only takes a simple registry entry change to resolve. Start the registry editor (regedit). Then go to the registry branch:
and change the value for "BasicAuthLevel" to "2" (decimal). Then restart Windows.
For actually setting up the web folder location, I found this tricky to find (it seems to keep changing in Windows). I found it through Windows Explorer, just highlight 'Computer' and right-click and select 'Add a network location'
Update (10/29/2010) - It appears there is a bug when using Windows 7 and UCM 10g (Bug# 9484798). I was connecting to a UCM 11g instance which does work OK. Changing the Title to reflect this is for 11g. Apologies for not checking this on 10g before posting. This will hopefully be resolved in future patch releases.
