There is a time and/or date difference between the client and server

We keep getting the 'There us a time and/or date differerence between the client and server' error appearing on our workstations.  I have been synching with various different NTP servers, changing to others but still the problem persisits. Is there any was to reset back to using the microsoft time service as I'm getting hacked off with trying to use an NTP service?  I never had any of these problems before changing to an NTP service and I don't have the time to keep messing with it, I'm ready to go back to Microsoft time!!

First start by making sure that there are no group policies defined that configure the ntp client on your machines.
Then to restore the default ntp behavior, run the following commands in a command prompt on all machines in your domain (including the DC):

net stop w32time
w32tm /unregister
w32tm /register
net start w32time
w32tm /resync /rediscover

This will make sure that all clients will sync their time with the DC authenticating them, DCs will sync with the PDC emulator.

Finally, configure the SBS to sync with an outside source: open a command prompt and enter (replacing <1.2.3.4> with the time server of your choice; the ,0x8 at the end will tell the time service to run in ntp client mode):

w32tm /config /manualpeerlist:<1.2.3.4>,0x8 /syncfromflags:MANUAL /update
w32tm /resync

Time servers are here (I wouldn't use the default "time.windows.com"; I've found it to be unreliable); pick a time server geographically close to you, for example one of these:

Double click on the clock and go to "Internet time".

Hi Juddy,
Just a simple check, but has the server options in DHCP (Option 004) got the correct ip for the Domain Controller?

Thanks oBdA, I have gone with ntp0.uk.uu.net.  I followed your instructions and the commands all worked well, I'll keep you posted.

Tony 409, not sure about option 004 in DHCP?  I have Option 003 Router, 006 DNS Servers, 015 DNS Domain name.

As far as the time in an AD domain is concerned, you don't need to configure anything anywhere except the external sync on the PDCe. AD has a functioning time sync hierarchy by default, because Kerberos relies on the time being the same on the clients and server (within reason, that is 5 minutes by default).

If all works well, you should find entries in the System event log (a few minutes after restarting the time service), source W32Time, stating which time server the machines are syncing with (and whether it was successful). On domain members, this should be a DC, on the PDCe obviously the configured external source.
If you have a firewall that blocks outbound outbound connections, make sure UDP port 123 to the external time server is allowed.

Ok, all checked out guess I'll wait and see!

I find that using SBS outside of the Wizard driven administration can cause problems, however In the past with a similar problem to yours, I had to fire up the DHCP mmc snapin and specify the 004 option manually. A quick ipconfig /renew on the clients after this sorted the problem.

Ok Tony, I'll see how I go with oBdA solution then maybe give it a try.  Is there any drawbacks to using both methods at the same time?
