How to Fix Time Synchronization Errors

Handy Andy [SBS-MVP] posted this helpful time sync info to the SBS Group Leaders mailing list and on his blog today, and I thought I’d pass it along.

If your servers are not able to time sync lately, check out the batch of commands below.  This set of instructions is for servers that have been synching fine, and all of a sudden just stopped.  (If your server has never been able to time sync, see the M&M’s article on synching time on SBS. )

Here are the commands;

w32tm /configure /,0x8 /syncfromflags:MANUAL
net stop w32time
net start w32time
w32tm /resync

Copy and paste those commands into notepad, save the file as timefix.cmd on the desktop of your server.  Then just double-click it to run the batch of commands.  Be sure to watch the last command and make sure it says the sync was successful.

Note: you may want to change the time source to one local to you (here is a list of time servers), but works fine for me (GMT -5 Eastern USA).
