Unable to reconfigure DNS server IP on CWMS IRP VM

[Mortaza Rohani]

Hello, I have a problem exactly the same as this bug in cwms 4 MR3.
The workaround is creating admin record in DMZ DNS server and i have tried this with no success. The error is “DNS is invalid”.
I have these records on DMZ DNS server: IRP,meeting(different from local DNS record), meetingadmin and CWMS.

Is there any other solution?

Thanks

Did you try to put the server in maintenance mode and then restart it, u could also try to upgrade to the latest patch "Cisco Webex Meetings Server 4.0 MR4 Security Patch 5"
