Hi Shingei, This maybe a long shot, but anyway, have you added the sub as a UCM server on the pub before you tried to add it as a 2nd node?

The error message as per attached jpg "Configuration Validation with CUCM-PUB Failed". I've did some research based on the error message, either from CISCO or some older post. What i've tried out was: 1. Adding a NTP server to CUCM-PUB. CUCM-PUB was able to get the time source from my WINXP modified NTP server, and can be viewed from CUCM CLI. 2. Changed of Security Password. Based on CISCO explanation, it could be due to the security password mismatch between CUCM-PUB and SUB. I've reset the security password and reboot the CUCM-PUB, but still got no luck. I did tried to input an "incorrect" Security Password while adding the 2nd node, it did correctly prompt that the password was error. So confirmed that the security password entered was correct. 3. Some post mentioned that the MTU for the CUCM, will have some issue if leave it to default, but i'm not too sure what does it mean? Should i change it to MTU size to 1492? I'm currently using VMWare Server 2.0. regards, Shingei
