Last Modified: 2012-05-07
I'll set my clock to the correct time (double-clicking on system tray icon, from "Date and Time" window i click "Change Date and time", and then i will manually set the time).

The next day i'll log in to the computer and notice the clock is five minutes slow again.

what is going on here? how do i fix this?

Is your Windows 2008 server the only server in your network?

Commented:
The server with the PDC FSMO role acts a time sever for the domain.  Find which DC holds this role and check that it has the correct time.
This  would be a problem if your system infected with spyware/malware. This is typically because of the amount ofrunning processes that slow down the overall clock speed. As a resultyou could be witnessing what you are. Therefore the first thing I wouldsuggest is to make sure you are free and clear of the spyware/malwareissues.

Now that you have done this, make sure you have the internet enabledtime sync set by double clicking on the clock, click on the INTERNETTIME tab and make sure check-box is enabled and you can then even clickUPDATE NOW. This should take a few seconds but not much more then that.

You can learn more about the internet clock here from the microsoft support pages:

If the lag time increases gradually such that 5  mins, 10 mins, 15 mins.... then it is the CMOS battery fault. Try Changing the battery
Is your Bios time runs correctly?

Open command prompt Run/Cmd and type in the command: "net time /set"

This will show where the server is syncing it's time to. As DCMS said this is your PDC by default but I believe could have been changed along the way.
Make sure the PDC FSMO server is getting its time from an accurate reference, like n.pool.ntp.org (where "n" is 0, 1, and/or 2).  Try this link as a starting point for background info: http://technet.microsoft.com/en-us/library/cc816633(WS.10).aspx

gsnshankar:  this server has 8GB of ram and typically is running between one and four virtual machines at a time.... also for some reason random apps will creep up to over 1 gb of ram use (ex: firefox, pidgin (go figure?!), chrome, etc).

Sorry if I mislead with the net time comment, I was more concerned with where the server was syncing it's clock and misinterpreted the way to get that done. Braker15 I hope we can get your time issue resolved. As for the programs eating up RAM it is probably unrelated to the issue but we could try to address that separately.
@ tigermatt

 I have read this point a while ago while surfing and heard such problems may be due to a spyware/virus .  I don't remember exactly.  But here are few links that have discussions about Slow down of system clock due to a spyware/virus attack.

http://www.techsupportforum.com/hardware-support/motherboards-bios-cpu/380715-computer-system-clock-going-slow.html

http://www.geeknewz.com/board/lofiversion/index.php/t3333.html

http://help.lockergnome.com/windows2/System-clock-running-slow--ftopict446993.html

Also I heard that some programs can make system clock run @  a slower speed than the real time.  (such as its one second equals 2 real seconds) . I believe such problems are possible and existing. Is it wrong?


May be the point is unrelated to this problem and if yes, just ask the user to ignore the point.
