Little rusty on setting this up but if I recall if I choose to setup roaming profiles at the user object level then I simply need to create a share with the appropriate share/NTFS permissions then assign the UNC path in the Profile tab in ADUC? We are running Win 2008 R2 with Win 7 SP1 clients.
If this is correct then I have done this and the profile will simply not roam...no errors in event log, the test user simply logs in and has a normal local profile. While I am logged in as this user I can access the above UNC and create a folder so I think permissions are ok.
Originally this computer and test user were in an OU where I set a GPO setting up Folder Redirection. Thinking that I possibly configured something incorrectly there I moved the user and computer object to a basic OU where only the default domain policy is applied. No change.
I don't remember getting this part working to be such a hassle so I am at a loss now how to troubleshoot further.
Thanks
