When you have My Document folder redirection using Group Policy, and you have change the location from A drive  to B drive, few of the client will have the folder syncronization issues. How to resolve it!!!

First of all, A drive will have to give the sharing and security permission, as before, Log on to the client machine, with his credentials..Let the sync happen on the old (A) drive and once it is finish, goto Start->Control Panel->Folder Options->and go to tab Offline files. At the bottom of this tab, you can see a DELETE FILES… button. Hold down Ctrl+Shift key and then click the button, there will be a window pop up

Click YES and close the folders, and then restart it..do not unshare the A drive sharing…once the client machine gets restarted, it starts syncronization with the new drive (B) and if you rightclick on the My Document properties, you will see the new My Document folder redirection path, as mentioned in your Group Policy. Once the syncronization is done, you can unshare the A drive.

Now user is on the New My document re-direction path….!!!!!!!!!!!!!!!!

This is a typical scenario of XP machines. When it comes to Windows 7, you need to go to Start->Control Pannel->Sync Center… Here you have full options to select it.
