You can and the way to do it is via NTP (Network Time Protocol).

You need an NTP time server for one of your NT boxes (say the PDC) and an NTP client for the NW 3.12 server.

The NTP server "TimeServ" v1.5 is provided on the NT 4.0 server resource kit CD.  Version 1.55 is available for download from ftp.microsoft.com, check out home1.gte.net/dougho/TimeServ.html

You need to install TCP/IP & RDATE.NLM on the 3.12 server.  RDATE.NLM is available from www.futureone.com/~opeth/freenlms.htm.

RDATE allows network administrators to synchronize the time of a NetWare 3.x or greater file server with the time of a nearby UNIX host (or any other host that supports the network time protocol). In this case it will be your NT time server.

When you read the text file that comes with it, you will notice it supports both TCP & UDP connections.  We have had better results using UDP.

Further possibilties.....

To really keep your clocks up to date, you could source your NT domain's time from an external time source.  Some such options include: -

1) A Stratum 2 or 3 internet time source (Many Navy sites provide such a service).  Your NT domain updates its time via NTP.  A fairly cheap solution if you have a connected network.

2) A telco provided external time source.  Accurate enough for most business needs and not too expensive.  Check with your local telco provider.

3) A product like a Coetanian Systems TSS-100.  This beast accepts time direct from GPS satellites and is rated as a Stratum 1 time source.  A must for the discerning buyer's time requirements !  Check out www.Coetanian.com.

For more info on NTP and time syncronization in general, check out www.eecis.udel.edu/~ntp/index.html.

Have Fun.

Hello,

it seems that timeserv (on the NT server) is not a NTP Server - just client, right?
Trying to get the time via rdate (on the 3.12 Server) shows:
"protocol not available"

Using the /u (udp switch): "all hosts failed".

Is it possible to configure timeserv as ntp - server?
