Backup Exec 2012 various issues

Hi,

I have several issues with BE2012 so here goes:

1.) The Agent on the CAS cannot establish a trust with itself - it reports that the logon account provided is not a member of the Administrators group. So this server will not backup.

2.) We have 2 media servers, however all the VM servers backing up to one of these MS's are failing with Authorisation errors

3.) With NDMP restores at the first screen I do not receive any option for selecting the restore type, e.g. select files

any ideas, this isn't a good position for our business to be in.
