DHCP on server 2012 cluster

I had a problem with authorization of DHCP server on server 2012 Cluster. The server have teamed adapters with Convergent  Switch (I am not sue it was a problem), So then I try to authorize the server it cannot fully authorized (meaning it still think it is not authorized despite if you try to see authorized server you will see it, but with a bogus IP), and object in AD has the bogus IP address like 250.0.0.1. In event log I have the error:
