I'm having the same problem in 7.0(2a), and like Matthew, didn't have issues using 6.1(2) in VMWare. I disabled NTP, but now my 7941 will not keep in sync with CallManager; IP Communicator works fine.<br><br>John<br>

I have an ISR configured as an NTP master on the same subnet as my VMWare<br>
host and guests. NTP appears to be working fine.<br>

VMWare recommends not using NTP on guests. Synch the host and let the<br>
guests follow the host.<br>
