[cisco-voip] Still confused on Unity Time Sync

[Micah Bennett]

Hello All

I am trying to understand and confirm where my Unity server is pulling
its time from.  My CCMs and IPCC servers are all working correctly.
They are using the NTP service and the configuration that is specified
in the ntp.conf file on each server.  

We are using Unity 4.2.  This server (Win Server 2000) is part of our
Domain because we are using Unified Messaging tied to our exchange
server. 

When I went to a command prompt on the Unity server and tried to do "net
time" I get and error message "System Error 5 has occurred".

I have read and re-read this document from Cisco and I am still lost.

Some other time documents from Microsoft mentioned the registry entries
under W32Time so I went there on the Unity server to see what was
configured.  
In
\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters
I found a reference to the IP address of my Call Manager Publisher
server. 

My guess is that our install partner hard coded the Unity server to
point to our publisher instead of just letting it pull from the domain
controller (pulling from the domain controller appears to be the default
setup when using the W32Time service.)  I can not find any reference in
Cisco docs to these registry entries, and the Microsoft reference seems
to be only for Server 2003 not Server 2000.

It seems to be working and the time matches across all my systems.  Has
anyone seen this setup before?  It sure is proving difficult to get an
understanding of our configuration, when even the initial install from
our partner does not seem to match the documentation. 

Thanks in advance for any guidance.
