CUCM 10.5. DHCP not working

Hi!

I have a strange situation. After upgrade from 10.0 to 10.5, DHCP on CUCM is no longer working.

Bug or there is some new security settings somewhere that prevents CUCM to be DHCP server??

I found that there is no any

I found that there is no any configuration in /etc/dhcp/dhcpd.conf file !!!!

Also, dhcpd.conf file have wrong permissions (root:root) while on CUCM 10.0 is ccmservice:ccmbase.

After fixing permissions...still no any configuration in dhcpd.conf file (after restarting DHCP Monitor service).

 

Very BAD Cisco...very BAD...You are getting worse and worse...

Nadeem,Do you work for Cisco?

Nadeem,

Do you work for Cisco??  Do you and your co-workers find this acceptable (or maybe funny) that you have broken the most basic service on this box?  How on earth did this make it through testing and QA at Cisco - or maybe Cisco doesn't have any QA, seems like that's the case now a days.

Earlier this week I found out you don't test your phone firmware very well, or maybe at all.  And now I see that you don't test or verify the simplest things in your server side software.

Either way I'm sitting here with a customer rebuilding DHCP scopes because our upgrade went completely sideways.  My customer's impression of your products and services, these are his own words - "Cisco is a joke, they are now lower than Microsoft in my book, this is just plain sad"

Way to go Cisco - you really knocked this one out of the park lol

12 years of Cisco VoIP - and I'm at a loss for words on this one,

This is now showing as resolved in 10.5(1.11005.1) which appears ot have posted a month ago. 

Please provide this ES to the customer or have them use a non CUCM DHCP server.
