Time Synch not working - 2nd post

[Newbie]

I ran the following command on a server (A) with AD installed on Friday
net time /setsntp:time.nist.gov
net stop w32time
w32tm -once -v
net start w32time


I ran the following on my other server (B) (also has AD installed)

net time /setsntp:servername
w32tm -once -v

Everything seemed ok but then I have come in this morning and the B server
is out of synch by 5 mins

In the event log for server B I have the following:
The Windows Time Service was not able to find a Domain Controller. A time
and date update was not possible.
and

Because of repeated network problems, the time service has not been able to
find a domain controller to synchronize with for a long time. To reduce
network traffic, the time service will wait 960 minutes before trying again.
No synchronization will take place during this interval, even if network
connectivity is restored. Accumulated time errors may cause certain network
operations to fail. To tell the time service that network connectivity has
been restored and that it should resynchronize, execute "w32tm /s" from the
command line.

In the event log for Server A I have the following:

The NTP server didn't respond

I have tried running w32tm /s but this has made no difference

What am I doing wrong and what do I need to do?

Is Server B a Domain controller in the same domain? If yes, why are you
setting the time server? By default, All DC's in the domain use the PDCe
as their Time Server and all clients use there Logon Servers. So the only
server that should be set for time source would be the PDC of the domain.

Also, are the Server A and Server B on the same subnet, is there any
firewalls between the systems.

Thank you,

Thanks for replying.

My network is as follows:

3 Win 2k servers all with Active Directory installed. All on the same domain
with the same subnet mask - no firewalls between them

I was told to choose one server and point the timeservice to synchronise
with an external source. I ran the following on Server A

net time /setsntp:time.nist.gov
net stop w32time
w32tm -once -v
net start w32time

I was also told to make the other servers synch with the one that I had told
to synch outside. I ran the following on the other two servers:

net time /setsntp:A
w32tm -once -v

This seemed to work initially but after the weekend Server B and C did not
have the same time as Server A

What do I need to do to put this right?

Thanks Again

On server B and C:
net time /querysntp

Do they return the proper servername for server A?

No it returns:
This computer is not currently configured to use a specific SNTP server

Why is this when I have run the following on the server:

net time /setsntp:A
w32tm -once -v

On server B and C:
net time /querysntp

Do they return the proper servername for server A?

On server B and C, from the commandprompt:
net time /setsntp:servername (where servername is the complete name of
server A)

Check with net time /querysntp to see if it is set to server A, then do the
w32tm -once command on server B and C.
