Network Time Adjustment / downside??

By ragsol ·
We need to change the time on the 2k3 server by minus 6 mins. Could someone suggest the best way of doing this with the least amount of disruption, The PCs and everything are all\picking their time from the server so they are also 6 minutes fast. Thanks Mike

you can use the time command to enter a new time from the cmd prompt type time, enter new time, or you can use w32tm to apply time against an external ntp server. You will need to open UDP port 123 to access the ntp server.

You should be able to just set the time on the server. As long as the clients update their time from that server you should not have an issue.

cm5400 is correct. clients should sync time with the server w32 time service. The server time service then can be setup to sync time from NIST time service.

Clients will sync their time with the domain controller that authenticates them.
If the time between clients and servers get too far apart (5 minutes is the default allowable skew) you will have Kerberos issues. You might want to do 3 minutes today and the other 3 another day. Or you could just have everybody type NET TIME \\Server /SET /Y after you set the server correctly.

If your domain controllers can access the Internet, you should be keeping time on one of them with a public ntp server. You can go to for a list of ntp servers to choose from.
