Then you need to make the protocol rule.

Is no DMZ yet....internal network sits on the other side of the ISA box :/

Here is a link for a good article on setting up an Authoritative Time Server
on Windows.

I used this to configure my Internal Network and DMZ to get out through the
ISA Server

and sync the time.

First you need to make a client address set for the Domain Controller (or
chosen server)

 

Next make a protocol rule for this client address set.

 

Allow NTP (UDP) and Time (UDP) for the protocol rule.

 

Remember- internal network=protocol rule          DMZ= packet filter 

( do not create both )

 

I used the ntp2.usno.navy.mil server at 192.5.41.209

 

Another good site for info to check out is www.labmice.net

Good Luck

Im using the ISA Server itself for this. 

All local and Fixed 123 is setup...does it need to be changed to dynamic
instead of all?

Where is the box from which you are runnning w32time -v?  Is is an SNat or 
FW client?  I assume your PF is UDP Send receive with dynamic local port 
and fixed remote port 123, right? 

I've done this and it works fine.
