Personally...I don't use NET TIME at all. I wish they'd either do away with it or make some kind of statement about its uselessness (my opinion -sorry!). Use W32TM to test your 2000 (and up) machines.
You should sync your forest root PDCe to whatever device you have as your reliable time source (XP, hardware clock, etc...), and let the other machines default to the hierarchcical sync. scheme (DOMHIER). I've seen this question asked A LOT on this list, and I think it is one of the easiest answers. Sync ONE machine (the PDC of the forest) to a reliable time source, and leave every other machine in the forest alone (unless special case has tighter requirements than Kerberos/Windows). Done! -DaveC Reuters CIO Infrastructure -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Abbiss, Mark Sent: Wednesday, April 13, 2005 10:33 AM To: [email protected] Subject: [ActiveDir] Using "net time" Following on from my earlier question about time synchronisation, can anyone please tell me, when you type in the command "net time", just where exactly how does the client determine where to pull this information from ? I ask because I assumed it would be querying its logon server by default, however in my case it is querying a DC from a sub-domain ?!?! Why on Earth is that ? The DC in question is not configured as a reliable time source (The "AnnounceFlags" value is 10 and not 4) I am confused and bewildered. Thanks again for any help. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Abbiss, Mark Sent: Wednesday, April 13, 2005 4:15 PM To: [email protected] Subject: [ActiveDir] Time synchronisation in a W2K domain I was recently handed a new hardware clock to install into our domain. As the device needs to be placed in an area with good radio reception I decided to install it onto a PC. Our server farm is located in a secure bunker with no reception at all. I know the usual time sync model is for DC's to get the time from the PDC role holder and then the time filters down from there to members servers and workstations. However, my PC is running Windows XP. So the question is, is it possible to set the XP workstation (with hardware connected) as the reliable primary source for time in the domain ? Should the Windows Time service be disabled on the PC ? What changes need to be nmade to the PDC Role holder and other DC's in the domain to make sure they are forced to sync with the XP workstation. Or is it just not possible to use an XP workstation ? I have noticed that some of my machines are synching with the PC but others are not and I have not as yet determine why there is this erratic behviour. If I use the "w32tm /resync" command then on some machines it works and on others it doesn't. Do I need to manually configure all DC's t point to the XP machine ? Do members servers need special configuration ? Why are general user workstations not showing the same time as the Time PC ? Any advice greatly appreciated.
