I have a WebDAV set up on my Windows 2008 R2 server using IIS. When I try to mount it on OSX using finder I have read-only access. What do I need to change to get full access?

I have added my account to the WebDAV rules, I have rw permissions on the disk and enabled simple_lock.


  • I can mount the location on Windows machines

Have you verified that it's not a Finder issue, e.g. by connecting using Transmit or Cyberduck? – Daniel Beck Jun 3 '11 at 20:49
Whoa! Weird combination of technologies there... – Code Bling Jun 3 '11 at 20:54
@Daniel, I can't seem to mount it on Transmit.. I am running the WebDAV on a port different from 80, but I don't think that should be a problem. – Jens Jun 3 '11 at 21:05
Can you mount it on any system other than the one server? – Daniel Beck Jun 3 '11 at 21:20
I can mount it on my Windows 7 machine without any problems. – Jens Jun 4 '11 at 9:19

OS X Finder requires a WebDAV server that supports WebDAV Class 2 locking. The windows WebDAV only supports WebDAV Class 1.

Use another product such as BarracudaDrive that supports WebDAV Class 2.

I thought IIS 7.5 had this supported. I have been able to connect with write access with enabling anonymous verification enabled. – Jens Jun 9 '11 at 8:41
