Issues setting up DAG between servers Exchange 2013

Hello,

Im trying to create a DAG between 2 servers (both mailbox and ca) i managed to create this without any errors displayed at that time however when i use "test-replicationhealth" in my shell it says the following:  There were database availability check failures for database '...  i tried looking in the log file however that didnt help me much.

[2014-01-13T07:44:46] new-dag started
[2014-01-13T07:44:46] commandline:         $scriptCmd = {& $wrappedCmd @PSBoundParameters }

[2014-01-13T07:44:46] Option 'Name' = ''.
[2014-01-13T07:44:46] Option 'WitnessServer' = '233SVR03'.
[2014-01-13T07:44:46] Option 'WitnessDirectory' = ''.
[2014-01-13T07:44:46] Option 'WhatIf' = ''.
[2014-01-13T07:44:53] New-DatabaseAvailabilityGroup passed the initial checks.
[2014-01-13T07:44:53] New-DatabaseAvailabilityGroup completed successfully.
new-databaseavailabiltygroup explicitly called CloseTempLogFile().

could someone tell me how i can find out why the DAG isn't working, or give me a push in the right direction?

Thanks,
