Folder redirection Server 2008 R2

Hello,
I have setup a RDP server and can connect to it remotley no problems
I want to do folder redirection not only for RDP Sessions but ultimatley for other user groups.

For the moment I am just testing the server using Remote desktop logins from a Windows Vista PC offsite i have full access to to Admin console using other software.

I have a secuity goup called "RDC Group" which are allowed to remote in. This works

I have set a computer policy on the server to move all user profiles to a network share
\\myservername\profiles$ this also seems to work and means I don't have to enter it manually into each user profile

My problem
I have setup folder redirection in group policy to redirect users data to a network share

\\myservername\userfiles

make note that previously i was using \\myservername\userdata$
I had all sort of problems where the redirection of every folder was working correctly except the "documents " folder which for some reason was being created inside a folder called "users" inside the userdata$ folder

example
user1 would log in and folder redirection would occur in the correct location
\\myservername\userdata$\user1\appdata,desktop,etc
I would also end up with
\\myservername\userdata$\USER\user1\my documents

OK i thought i could live with that but when I created any subsequent users this would happen

user2 would log in and folder redirection would occur in the correct location
\\myservername\userdata$\user2\appdata,desktop,etc
I would then NOT get as previous
\\myservername\userdata$\USER\user2\my documents

but instead the document folder would get locked into the local user profile
c:\users\users2\documents

so because of all this as stated earlier created a new share

\\myservername\userfiles

duplicated the permissions from "userdata$" and now nothing gets created

Any tips on best practice would be grealy appreciated

i am using the option of folder location depending on users group in the folder rediction group policy as soon i plan to move groups of poeple from another server onto this

the primary domain controller in this domain is 2003 if that has any bearing.

Please assist
