pre install warnings

Hi,

We try to upgrade from 2010 R2 to R3 for our Dell Tape library, the pre install shows 3 warning,

1. one says this machine is a Termial server.

2. one or more devices connected to this comuter are either not connected or not working.

about 4 month ago we had to replace the drive of the library after that we did remove the defect drive and the BE shows only one drive.

3. warning regarding the version, I did run the liveupdate and it says there is no update availble.

how can correct these warnings?

Thanks
