I have setup a Windows Server 2008R2 with DNS and AD. When I define a shared folder on the Server and connect to it via \domain.lan\folder I can see the content but if I try to change something in the folder I get the error "element not found". This behaviour is always the same. It doesn't matter if I try connecting directly from the server or through a windows 7 client. BUT: IF I ACCESS THE FOLDER VIA IP ADDRESS OF THE SERVER e.g. \192.168.0.22\folder all works fine. So my guess there is a big problem with the Windows DNS Server. Pinging domain.lan results in the correct IP Address so it is resolved correctly. I don't know where the problem can be.
BTW: I could reproduce this problem exactly with Virtual Machines on my PC and different names and IP Addresses...
Does anybody have a guess?
\\server.domain.lan\folder
