V30L CE 6 upgrade

I have been able to resolve the issue describer below.  To do so I have to log the device into a DC as a administrator after this I am able to login to one of the remote desktop servers.  I also find if I use  different account to logon I am successful which make no sense but works.

I am currently attempting to use smart card readers *** V30L after upgrading to Win CE6. I have not been successful using smart cards with CE6.  I was successful using using these same devices with smart cards readers using Win CE5 but not with CE6?   

Hello I am upgrading Wyse V30L thin clients from Windows CE 5.x  to Windows CE 6.0. B674.  I am using a bootable USB flash drive.  All is well once the device sees the USB flash drive. The process of getting the thin client to see the flash drive is a bit hit or miss.

The thin clients connect to a Windows 2012 domain.  Prior to the upgrade the thin client was connecting to one of the remote desktop servers without issue as are other Wyes thin clients.  After getting upgraded to CE 6.0 the thin client is unable to connect to a remote desktop server in the domain.  The error message:  An authentication error has occurred (Code 0x80090308)

Has anyone seen this?  Suggestions are appreciated.
