Hi
The error message indicates that there is problem with OS admin credentials for cucm-02 and cucm-03.
Can you please verify if those are correct ?
Also are you using any customized log on message on the CUCM nodes ? If yes then you may be running into the following defect : CSCur45491

Workaround:
Need to delete the Customized Logon Messages on the application nodes
Regards
Aditya
