I have come across this twice at work now and thought it would be worth the share for those running Windows networks.
When running a Windows Server 2008 (or R2) Domain network, you may have a group policy for your users pushing out mapped drive configurations. However on Windows 8, these policies do not apply.
To fix this, open your policies and modify the mapped drive object. Uncheck the Reconnect option, and this will now allow you Windows 8 clients to map the drives with your policies.
Also note that this change, from my testing, won’t affect your existing Windows 7 (or older) clients. These clients will continue to map the drives specified.
Reference:
http://support.microsoft.com/kb/2795944 seems to fix it…
This is not the way to do it as it will impact mappings when moving between online & offline. The bug was resolved with KB 9725944 for Windows Update.
I have this update and still drives are not mapped. After restart they just disappear.
Sorry, I can't seem to find that patch. Can someone link it for me? I will try it out and update the post for future users.
