Windows 2008 R2 OS Clock runs fast and gains 2-3 seconds in a day

I have got many servers running Windows 2008 R2 Ent 6.1.7601 Service Pack 1 Build 7601 on HP DL 360 gen7 servers. The problem is that the clock being maintained by the OS runs fast. NTP is being used to mitigate the issue but need to identify the root
cause of the problem. I have verified that the hardware clock is not at fault as after running the system for 5 days the clock went ahead by nearly 12 seconds and when the server was rebooted the OS clock showed nearly accurate time. NTP was turned off completely
on this server for this testing. As at power-on the OS picks the time from the BIOS/Hardware clock this proves that the hardware clock is working fine and once the OS is up and running, the timer/function that it is using to maintain the system clock is not
functioning properly. The systems are not under any kind of load and no temperature fluctuations have been observed. Enabling HPET also did not help.
Please do not answer saying, "use w32tm or ntp" as that mitigates the problem but does not solve it. The server is not a DC. The OS is running directly on the server, no VM involved.
Thanks

Hello,
the Windows time services was and is never built for high accurate time. So you have the need for special devices.

STRANGE!!! Windows Xp clock running fast....

Hi guys. Youve helped me in the past so I hope you can help me again!
My MSI system has been running solid as a rock for about 1and1/2years now. Very happy with it. untill now..
It all started after I installed a bluetooth dongle (or so i though). I suddently realised that my xp clock was running fast about 10seconds every minute. I though this is weird so did the obvious things... restarted comp checked bios which was running fine. It is only when I get into windows that it starts to run fast. I uninstalled the bluetooth software thinking it was the culprit but obvoisuly wasnt. I then decided it was about time that i reformatted again anyway so reformatted and sure enough it fixed the problem, proving to me that it is a software problem not a hardware. Then, after about 4 months of my new reformatted system being up and running it suddenly has started doing it again. I havent even installed the bluetooth software or anything that is obviouslty the problem. I dont know if this has anything to do with it but my firewire card has also stopped working for somereason. I replaced it with a new one and that doesnt work either!
Any ideas anyone, ive searched the whole forum and internet and it doesnt seem like a common problem!
Many thanks
Jon.

Hello hurndall:
I see you are running XP/SP2 with all patches. Besides that, are you running any third party software that monitors communication? Looking at this from the paranoid perspective, have you run a spyware/malware sweep of your system?
The Windows Time service that you stopped is used to synchronize time across a network and does not directly control your RTC. Unless systems on your network are using it there will be no effect, so you can probably leave it stopped.
Regarding your fast clock problem, I have had this type of problem on PC platforms that were using the RTC interrupt to start background tasks such as data logging or other hardware. The hardware RTC clock uses IRQ 8; old MS-DOS software would modify the code associated with this interrupt to give pseudo-real time operation to specific processes. As I recall there is/was a timer that pinged this IRQ at 13.8 ms intervals and so kept the clock going. Although the usual symptom in these cases was a clock running SLOW, not fast, it is possible to have a clock run fast due to a bug in the added software.
You can do a rudimentary check on your system by starting Control Panel - System - Hardware - Device Manager - View - Resources By Connection - IRQ
Look at IRQ 8 - it should only be associated with the RTC function.
This is probably not going to get you anywhere but it is something that should be checked anyway.
Looking at your problem from the other direction, it seems that your system has issues with communication devices - Bluetooth, FireWire and now Remote Login. I'm not sure how you are communicating with your system remotely (network - i.e., ethernet or dial-up, i.e., modem), but you might want to reinstall/update the drivers associated with your Ethernet or Modem hardware. Since the problem seems to go away on a reinstall, which refreshes all these drivers, you might want to try this. It's a lot simpler than a reinstall.
The Remote Login Service installs and/or starts a number of services that depend on the svchost.exe module. It seems unlikely that there is a problem there but you might want to make sure that svchost.exe is truly the SP2 version or whatever is the most recent. I don't know if any patches since SP2 have modified it. You could look at another XP system can check the properties of svchost.exe.
My system reports
File Version 5.1.2600.2180 (xpsp_sp2_rtm.040803-2158)
Product Version 5.1.2600.2180
for svchost.exe
Sorry I can't give you any more specific help.
Good luck,
ss

Clock runs fast

I just got my new Mac Pro (3.0) and I've found the clock runs fast, easily slipping an hour every day. Even when I have it set to use Apple's time servers, I've found that the clock easily slips several minutes into the future.
1) Can I fix this somehow?
2) Can I get "set date and time automatically" to update more frequently?
Thanks!

Thomas-
Are you running Leopard Server? I am, and I think I've narrowed it down to that.
On a separate, newly formatted drive, I created two partitions. On one, I installed Server. Bare bones, no updates, etc. On the other, I installed Client. End result? Server runs fast (4 s/m), Client runs fine. Client also runs fine on my MacBook. When I make a copy of my Server drive to my MacBook (Restore from Disk Utility), I have no time loss.
So, it seems it's combination of software and hardware (in my case). I really hope you're running Server so I can report this bug, somehow.

Mavericks clock running fast

Since my Mavericks upgrade, my 27" iMac clock runs fast. It was about 3 min fast today after a few weeks since I reset it last.
If I open my Date & Time Preferences it corrects the time, but then continues to run fast.
I have it set to: Set date and time automatically: Apple Americas/ U.S. (time.apple.com)
I do not have a check to set time zone automatically, but chose the city.
Any suggestions?

Videos are running fast and without any audio in Firefox 21 and Flash 11

Whenever I'm running any videos in Firefox 21, it runs fast and there is no audio. I've recently upgraded to Flash 11. I've tried downgrading to Flash 10.3 with Firefox 21 and even downgrading to Firefox 11. Also tried disabling the hardware acceleration from Flash plugin.
The problem still persists.
The videos run fine in other browsers like Chrome and IE8.
Could anyone kindly help?

Hello,
Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
*Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
*In the Firefox options window click the ''Advanced'' tab, then select "General".
*In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
*Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
[[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
[[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
Did this fix your problems? Please report back to us!
Thank you.

XServe fans running fast and loud

Good morning
I have searched the information base and tried a few suggestions without success. Hoping for another solution here.
I have an Intel based XServe (2008) (OS 10.6.8) whose fans are running faster (and therefore louder) than they have previously. This follows on the heels of a power outage (two of them actually) here at school, though the server is behind a UPS. The system identifier light is also blinking in a particular pattern - 4 flashes and a pause repeating.
The server is up and running, teachers are connecting to it just fine, the RAID is intact and online, the drives all look good according to Disk Utility. So, functionally, everything looks OK - the fans are just running faster and louder than before - noticibly louder than the other Intel XServe in the rack. The server is at the top of the enclosed rack with a space below it as it has been for the last 4 years.
This summer I took all the XServes out of the rack, opened them up, and blew the dust out of them (including a moth - truly a bug in the system), so the all the airways are clean and clear.
I have tried the suggestions I could find on this forum:
     restarted a bunch of times
     shut down and disconnect everything (including power) for a period of time
     reset the PMU/SMC or whatever it is called doing the front panel buttons with the blue lights on the lower row
     reset the PMU/SMC or whatever it is called by holding down the power button while disconnected from power
I have installed iStat Pro and the temperatures are averaging around mid- to upper- 30°C and the fans are running around 3000 RPM . The temperatures aren't signifcantly different that the other XServe, but the fans are running about twice the speed.
I had to reformat the RAID earlier this weekend and copy over the data files from backup and reassign permissions, but the server was running quietly after that was all finished. It seems to be post-powerbump that the fans became noisy.
Sorry for the long post, but I tried to include all the pertinent information. I would have tossed in photos and videos if I could have!
Any suggestions would be appreciated.
TIA
Greg

Did a little more searching about setting up LOM on the XServe and I think I have it figured out now.
I assigned a unique (different) IP address to Network 1 in the LOM dialogue box in Configure Server menu of Server Monitor since I only have Ethernet 1 enabled and linked to a switch using a unique (different) IP address for network traffic between the XServe and my clients.
I can now see (via Server Monitor remotely) that I have a dead blower in my fan array which, upon closer inspection, is also evident in the iStatPro display (one fan running at 18 RPM). Hence the blinking system identifier light and the other fans running faster and harder (and noisier).
Oddly enough, I have a replacement fan array in a box of XServe spare parts. I now have a weekend task.
Thanks for all the information to be found and the people participating in this forum. Love it.

Macbook pro 10.7.5 fan running fast and hot

Recently (past 2 weeks) my macbook pro (just over 1 yr old) 10.7.5 fan has been running fast and hot. It begins after uploading photo's into iPhoto '11. Sometimes it takes 30 minutes for it to cool down and run at normal speed. Uploads are usually 50 to 200 images. I verified the Activity Monitor CPU % and nothing exceeds 12%.
I did a restart twice this week which seems to be a temporary solution. Any tips to resolve this is appreciated.
Happens when running iPhoto is only app open.

When you were checking Activity Monitor, did you select "All Processes" from the drop down list at the top

Redirect Printer is not working in windows 2008 R2 Server( Server Running as AD and Terminal Service(both role in single server))

Dear Team
i need solution from Microsoft for the issue;
My infrastructure
- Windows Server 2008 R2 (Role - AD and Terminal Service)- Updated
- Client Machine running with windows 7 pro (Updated)
- Client Using RDP Client to connect Windows 2008 Terminal Session
- All are working fine, but Redirect Printing is not working (Through Windows 7 Pro) ... (HP Laser Jet 1020 plus - attached in Client PC)
- it is working fine from Windows XP
- i was done All terminal setting in both end, also try RDP Login with Administrator User, but issue is not resolve;
What Microsoft can say about the issue;
Thanks & Regards,
VIMAL PRAJAPATI | 09824111686

Have you checked the Print Service log in event viewer?
Here's How.
I have the Microsoft XPS driver on my clients, so I use that fact to my advantage below.
Click Start Button/Administrative Tools/Remote Desktop Services/Remote Desktop Services Manager on the RDSH server
Click the Sessions tab. PC’s are listed Under Client Name by their computer name. Take Note of the corresponding
ID. We will use this to locate the Printer information in the Event Log.
In the Event Log open Application and Services Logs/Microsoft/Windows/Print Service/Admin/ and Find the Event ID 823 entry that has the corresponding ID from the sessions tab you previously noted.
This Event Log Entry is created at Logon and you can only get the session ID when they are logged in.
This tells you what client printer was mapped for the client. The name that appears is the name of the Printer that was set on the client when the printer was installed.
See if you see any errors here.
If you see Event Id 823 with the following message “The default printer was changed to Microsoft XPS Document Writer,winspool,Ne00:. See the event user data for context information.” Twice in a row with no other messages in between, and the first occurs
at the time the user logged in, then their printer was not properly redirected.
You see the Microsoft XPS driver mapped for each session prior to Easy Print redirecting the client machine’s Default Printer.
Since your printer is the HP 1020 I would bet the driver on the client does not work with Easyprint. I would try the the HP Universal Print Driver or the driver for a printer that is very close, like the HP 1018.
Thanks,
Jeremy

Satellite L775D clock running fast

Our tech support friends are stumped by this one so I thought I would try polling the "unwashed masses":
The clock on the Satellite is always running fast, approx 15 minutes every 12 hours regardless of turned on, turned off, sleep, AC plugged in, AC not plugged in.
So far we have unchecked the automatic sync with internet time.windows and reset the BIOS settings, with no improvement.
Any thoughts / suggestions?
TIA Keith
Solved!
Go to Solution.

Let's start here.
Keith, open Services (services.msc) and verify that the Windows Time service exists and that Startup Type is set to Manual.
If it's not started, start it. If it won't start, give us the message.
If all that's okay, come back for more.
Also, tell us which Satellite L775D that is and the bitness of Windows.

Clock running fast

Since updating to Mavericks, I think probably specifically the latest update, the clock is running fast on my 2012 (thin) iMac. It can gain a minute in a day.
I'm set to Apple Europe (time.euro.apple.com.). If I turn this setting off and on again, the computer fetches the correct time.
Until recently I also had Set time zone automatically using current location (I'm on CET), but I've now unselected this to see if it makes any difference.
As a control, I have an older iMac running Snow Leopard sitting next to it on the same connection which has perfect time.
This 2012 iMac had no problem either with the time before Mavericks.
P.S. Also since updating to Mavericks I've had all sorts of sync problems with Mail/Gmail, 1Password and Dropbox, usually resulting in missing files. I wonder now if this isn't all clock related as it must be difficult to sync without an accurate clock.

OK Drew, I can confirm that booting in Safe Mode http://support.apple.com/kb/HT1564?viewlocale=en_US fixes the problem, at least as long as I stay in Safe Mode. I.e. the clock keeps perfect time.
I have now rebooted in normal mode and will monitor to see if the problem has been fixed permanently.
As an aside, in Safe Mode, Mail, message centre, Finder all behave weirdly. The message centre actually displayed text 180 degrees inverted in the vertical plane - like a mirror image ! I couldn't take a screen shot though, it would disappear when I tried to do this. I saw this behaviour somewhere else several years ago on my old computer in a different place - I think the Get Info window. It fixed itself after a few months.
Also, in Safe Mode, before actually logging in (but after rebooting), the clock is still wrong, but this time, strangely, it is slow, not fast. As soon as I log in the clock corrects and stays correct.
In fact, just logging in after a normal restart is also enough to set the clock correctly, but then it would start to gain time.
Anyway, will monitor and report back if my problem is now permanently fixed or not.

High Page Reads/Sec on Windows 2008 R2 64-bit running on VMware but very low Real Memory & Page file Usage.

Hello All,
Below is the server configuration,
OS: Windows 2008 R2 Enterprise 64 Bit
Version: 6.1.7601 Service Pack 1 Build 7601
CPU: 4 (@ 2.93 GHz, 1 core)
Memory: 12 GB
Page file: 12 GB
1. The actual utilization, be it a 15 minute sample, hourly, weekly etc, the utilization of real memory has never crossed 20% and the page file usage is at 0.1%. For some reason, the Pages/Sec>Limit% counter reports 100% continuously regardless of the
sampling intervals. Upon further observation, the Page Reads/Sec value is somewhere between 150~450 and Page Input/Sec is somewhere between 800~8000. Does this indicate a performance bottleneck? (I've in the interim asked the Users, App. Owners to see if they
notice any performance degradation and awaiting response). If this indicates a performance issue, please could someone help list down how to track this down further to which process/memory mapped file is causing it? and what I should go about performing to
fix this problem please?
p.s., initially the Security logs were full on this server and since page file is tied to Application, Security and System logs, this was freed up to see if this is causing the high page reads but this doesn't.
2. If the above does not necessarily indicate a performance problem, please can someone reference few KB articles that confirms this? Also, in this case, will there be any adverse effects if attempting to fine tune a server which is already running fine?
assuming App. Owners confirm there isn't any performance degradation.
Thanks in advance.

Hi,
Based on the description, we can try to download Server Performance Advisor (SPA) to help further analyze the performance of the server. SPA can generate comprehensive diagnostic reports and charts and provides recommendations to help you quickly analyze
issues and develop corrective actions.

VM System clocks running fast

I'm running 3 VMs (OEL R4) on a single host.
I've noticed the clocks in the VMs are running faster than the host.
I found a couple of threads about this in the XEN groups - including one about adding "xen.independent_wallclock=1" in sysctl but I get errors with that.
Right now I'm reduced to running a timesync (ntpdate) every 3 minutes to keep the clock on time.
It averages a gain of about 3 sec/min and even more than that when the CPU is 100% loaded.
Anyone else ran into this?

I found a couple of threads about this in the XEN groups - including one about adding "xen.independent_wallclock=1" in sysctl but I get errors with that.This setting only works on PVM guests -- by default, a PVM guest uses the hardware clock of the VM Server. Setting this option means the guest can keep its own time.
Right now I'm reduced to running a timesync (ntpdate) every 3 minutes to keep the clock on time.
Anyone else ran into this?Yes, it's pretty standard on Xen virtual machines. I always insist that clients run ntpd inside HVM guests and the Dom0 (for PVM guests) on all my Oracle VM Servers. You can also use the independent_wallclock option and ntpd for PVM guests if you don't want to run ntpd in Dom0 (or perhaps have no access to ntp time sources from the Dom0).
