I have been having this issue lately that I think is possible to avoid.
At the moment I have Windows Server 2008 R2 setup with the folders (AppData, Documents, Start Menu, & Desktop) redirecting to a folder called Fldrredir$. The other folders like Downloads and Favorites follow the roaming profile. I have this setup because I have a mixture of XP and 7 clients.
Lately I have had to work it Mac 10.8 clients into the mixture. They work well and I have noticed for instance if I set the folder called Fldrredir$ to be their home folder and mount for example H:/ Mac will mount these folders in the dock. Mac will also build the user's profile around the mounted folders (AppData, Documents, Start Menu, & Desktop). Since there is a conflict with the Desktop folder (both OS wants one in the user's profile) Mac will use the mounted folder and not create one just for it's OS. So any files that the user had on their desktop in XP or 7 will also appear on their Mac profile and Sync correctly.
The issue I have is that Windows calls their documents folder "My Documents" instead of "Documents" like mac. So I wind up with two folders. One that Mac uses for their profile "Documents" (that does not sync like desktop) and My Documents that will sync but is only accessible by the dock folder and not through Finder.
I wanted to know if I could have Windows redirect the My Documents folder like it does now but have it named Documents.
I am creating this server config right now so I won't have to rebuild actual profiles used by people. As of right now I am using test profiles.
Thank You.
