Windows Wime Service

if I type net time <return> it displays where the current computer is getting it's time?

If so , all our domain computers are pointing to a regular DC for time and I want to change it so that all domain computers point to the PDC instead. How do I do that?

Thanks everyone,

Ken

NET TIME /DOMAIN:domainname /SET

or

NET TIME \\computername /SET

for more information, please see the help of NET TIME:

C:\>net time /?
The syntax of this command is:

NET TIME
[\\computername | /DOMAIN[:domainname] | /RTSDOMAIN[:domainname]] [/SET]
         [\\computername] /QUERYSNTP
         [\\computername] /SETSNTP[:ntp server list]

Thank You bbao,

Problem I'm having is when running "net time" command i get this results below... Well in my network, Headquarter \\DCROOT  DC holds the PDC Emulator Role, which is the authoritive time server but when running net time command from client machine it points \\DC1NY which is located in New York (DC) instead of \\DCROOT. Is this normal? because i thought it should be pointing to \\DCROOT. I was told by somebody that "when the time source is chosen automatically, a different source might be chosen each time.”  is this true or how could I make it so it points to \\DCROOT (PDC Emulator)

Thank You bbao

U:\>net time
Current time at \\DC1NY is 12/29/2005 1:23 PM

Local time (GMT-05:00) at \\DC1NY is 12/29/2005 4:23 PM

The command completed successfully.

it is normal. anyway, if you have to use DCROOT as the time server, just use "NET TIME \\DCROOT /YES" instead.

Thank You for your expert advise :) but question is if i'm at a "site"  client PC should be getting it's time from local time server within a site? not from different site, this is the problem i'm having :( because when i'm running "net time" it goes to a time server in a different site instead of local site.

Once again Thank You for your advise
SysExpertCommented:
Then use the name of the Local server that you want or put it in a batch file or login script , so that it works automatically.

I prefer to use an automatic Time program from NIST that get the Time from the Time Servers on the INternet, rather than relying on loca servers.

see

http://tf.nist.gov/service/its.htm

It can be set to work automatically in the backgroung.

I hope this helps !

do you have DHCP deployed throughout your site? i think it should be great if you answer yes.

you may automatically specify your time server (NTP or SNTP based) to all your DHCP clients by assigning its IP address to DHCP options 4 (RFC 868 time server) or 42 (RFC 1305 NTP servers). the client computers then wont access a wrong time server.

using external (3rd-party) time server is recommended if possible, as what SysExpert mentioned above.
