We have Mac OSX 10.6.8 also and are connecting to Windows server 2003 using Active Directory. We are having the same issue. Can anyone provide some insight as to why?
We have several OSX 10.6.8 and 10.7.4 Macs connected to a Windows 2008 server with several shares including a Drobo.
When we attempt to move/drag files across from certain areas of the server to another, we keep getting prompted to authenticate which is being triggered by com.apple.desktopservices, if we enter our local OSX username and password (which have admin permissions), the username and password window closes but the move does not happen/occur.
There are no specific permissions set on the file shares at all, its all open so I don't know why this prompt keeps occurring, its driving everyone mad...
Strangely if we do a copy and paste of the file instead of moving it, then it works ok but then of course we get duplicates of files on the server...
Any help or advice would be greatly appreciated.
