Issue connecting to Windows Server 2008 r2 share from mobile device

view story

http://serverfault.com – I have created a local windows account on a Windows Server 2008r2 server and given that local account, amongst others, access to 2 shared folders. I have also connected various mobile devices (PPC2003, CE5, WM6.5) to the network using the same account details but when navigating to the share from the devices I can resolve to the server but can not see any of the shared folders. I have configured everything the same way as on our Windows Server 2003r2 server, which works, but can not see the shared folders on 2008r2. I have confirmed that the shared folder and accounts are set up correctly (HowTos)
