Issues by using external ntp time source on domain controller
Hello i have done the following on my 2012 R2 domain in a command promt
net stop w32time
w32tm /config
/syncfromflags:manual /manualpeerlist:"0.dk.pool.ntp.org"
w32tm /config
/reliable:yes
net start w32time
and when i type: w32tm /query
/configuration i get
[TimeProviders]
NtpClient (Local)
DllName: C:\Windows\system32\w32time.d
Enabled: 1 (Local)

so everything seems fine, but when i look at the clock on the server, the time don't update to the correct time, can anyone explain why?
Hi Stig,
Post us the result after running the below command on your PDC.
w32tm /stripchart /computer:<NTP server> /samples:<n> /dataonly
If this procedure fails, check the System event log for Time-Service errors. Check if NTP port 123 is opened in firewall to communicate with NTP server.
Thanks,

[Forum FAQ] How to sync time with a Domain Controller for a standalone server
As we all known, if a computer belongs to an Active Directory domain, it will sync the time automatically by using the Windows Time service that is available on Domain Controllers.
While a standalone server will synchronize with its local hardware time and Windows time server. (Figure 1)
Figure 1.
Under some circumstances, a standalone server is necessary in a product environment. We can sync the time of this standalone server with the Domain Controller using
the steps below:
1. Modified the value of the AnnounceFlags:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config
Under this entry we can see the default value of AnnounceFlags is 10 (Decimal), we configure the value as 5 (Decimal). (Figure 2)
Figure 2.
2. Confirm the value of the registry key below is set to 0:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpServer
Figure 3.
3. Configure the standalone server to synchronize with a specific time source (Domain Controller).
In our test, we configured our Domain Controller (192.168.10.200) as the time source. Used the following commands:
w32tm /config /syncfromflags:manual /manualpeerlist:192.168.10.200
4. Sync the time with the Domain Controller using the command below:
w32tm /config /update
From the figure below (Figure 4), you can see the after we did all the steps above, the time on the standalone server was synced with the Domain Controller.
Figure 4.
(Note: Peerlist is a separated list of DNS servers, or IP Addresses for the time servers)

Sleep issue when using external display
I use my macbook(lid closed) with an external apple cinema 20" display. When I wish to put the computer to sleep, when I will not be using it for a while, I click on the sleep menu item either in the drop down finder menu or by clicking on sleep from the menu that appears when I touch the display button. I have had erratic reponse from doing this using both methods of putting the system to sleep. Sometimes the macbook goes into sleep mode and sometimes it turns the display and system back on after a short pause following the activation of the sleep button.
Do you use a wireless mouse or keyboard?
I had the exact same problem with both my mini and my old ibook G4. Try unplugging one peripheral at a time from your usb ports to pinpoint which (if any) is causing the problem. This can take a while if the problem is intermittant like you say! -
Using external HD & Time Machine
Obviously cannot leave the external HD plugged in all the time on portable laptop so Time Machine can do its hourly backups so will Time Machine still work if I do twice weekly manual backups?
I have read Time Machine can do snapshots when on battery power is that only on batt power or does it do them anyway and then when the external HD is plugged in again then transfer the snapshots to the disc?
First time Mac owner so all is new, wonderful & confusing!!
ThanksRead the link below for more information on snapshots.

Using external database as source for Quicktime annotation automator action
Hi
I have approximately 1500 quicktime files which require annotations added to them (title, author etc).
I've been provided a spreadsheet with all the neccessary data. And I know there is an automator action that can add annotations to quicktime files but was wondering if either of the following was possible:
1) Can I get the an automator script to use this spreadsheet as a source for the values it is to enter.
OR
2) If I can get automator to add the files name to the annotations section (under title)
Greatly appreciate any help you can provide.
RegardsHI
Make sure you select the Initialize or Run methods, depending on where you try to define the database connection it will not let you do it.
Good practice would be to define the database and the connection in the initialize section, the SQL and execute in the Run section and the disconnect in the Finish section, however that could change depending on your needs.

RegardsThe thing to remember is that with the new Apple TV, all these things had to be written from scratch. The code that made these things work on the old Apple TV can't just be ported to the new one, but it had to be re-written.
The situation you describe, which if I understand you would require the Apple TV playing some content on streamed from iTunes and also Airplayed to an Airport Express, whilst the iTunes library is also streaming another track to a different set of speakers sounds like an incidental benefit, rather than what it was originally designed to do (and, I would suggest a fairly niche use as well).
I have to admit, it's the one thing that has been suggested as a use for the old ability to stream from the Apple TV to Airplay devices that can't now be easily recreated (although an iOS device could be used to set up the second stream). My initial feeling is that the demand for this ability would be too low for Apple to be convinced to add it, but I could be wrong.
EDIT to say that, on reflection, this ability could be useful where a household relies on Airport Express to play music in different rooms and where people want to listen to different content from the same library.
In this case, I think that the best solution if Apple wanted to make this easy would be to either allow iTunes to send more than one stream controlled from the computer, or to allow the remote app to get the Airport Express to pull the stream in the same way that Apple TV does.
Using the Apple TV as a kind of bridge is a fairly inelegant work round.

Using a Cisco Switch as the NTP Master time source for a Windows PDC
Hi all,
We have a closed network (no connectivity to the internet) and we have a Core router setup as the NTP Master for the rest of the network.
All network devices are getting the time synced as intended but we are having issues getting the Primary Domain Controller (PDC) registering to it as a valid NTP time source.
The problem we have is that we are affected by IOS bug CSCed13703 which rejects the PDC as an NTP associated device. Short of changing the IOS on the Router which is the main router feeding 30 other sites I would like to point the PDC at a different switch (an NTP Client switch) as it’s NTP source, rather than it going to the actual NTP Master.
I have changed the values in the PDC to point to a different switch (3750) that has it’s time synced with the NTP master, but the PDC doesn’t want to know. I assume it will only accept the time from an official NTP Master .
Could any of you fine people advise if what I am trying to do is possible and if so how I would go about it. I was thinking of setting the 3750 with the NTP Master command also, but I don’t want to confuse the other cisco devices in the network
Thanks in advance
DavidThanks Marvin,
I can confirm the Stratum on the 3750 is set to 15. This is due to the NTP Time source being an internal router and not an authoritative time source out on the internet. When setting the clock and using the NTP Master command on my internal router it sets the Stratum level to 14.
I have pointed the PDC at the Router (Stratum 14) and it does successfully sync time, but won't trust it as a valid source after the first sync. Upon reading I believed this to be the IOS bug as the symptoms are identical. Your theory of the PDC requiring a Stratum 2 time source is logical (especially in this scenario) but I have seen them use Stratum 4 before and it worked just fine.
I guess I could change the Router acting as a time source for the network to be NTP Master 1 which should force Stratum 1 giving the PDC and all other switches pointing to it a Stratumlevel of 2 which would prove it either way. I don't mind pointing the PDC at the router instead of the switch so long as it gets the time synced and trusts it from that point on.
I was going to make the 3750 switch an NTP Master for the Network and point the PDC to it (as per my previous post) but I have noticed this morning that the NTP Master command isn't available on the 3750 as it has no hardware clock!
Are you aware of any other way of forcing the 3750 to become a time source for the PDC without using the NTP Master command? I have looked at the NTP Peer command and I have ruled this out already and I still need the switch to be a client of the NTP Master Router on the network
Cheers for getting involved,

2. If I resync and rediscover the following error appears:

The computer did not resync because no time data was available.
3. I've also clearing the current time config, by
net stop w32time
w32tm /unregister
w32tm /register
net start w32time
But no change, it still shows the Local CMOS clock.

Craig BrandI suspected some issue with AV so uninstalled.
To resolve the Access Denied I followed these steps:
stop w32time
w32tm /unregister
reboot
regsvr32 /u w32time.dll
w32tm /register
sc query w32time -- you should see that the service is set to
shared mode -- this is presumably how it should be -- if you try to start right now, you'll get the expected 1290 SID-related error
reboot
w32time should now automatically start at boot up and be running -- that was my result -- it's running as shared, started on its own, and I can do the w32tm /query commands successfully
After rebooting the time service started.
I then repeated the steps:
net stop w32time
w32tm /config /syncfromflags:manual /manualpeerlist:"0.pool.ntp.org, 1.pool.ntp.org, 2.pool.ntp.org"
w32tm /config /reliable:yes
net start w32time
w32tm /query /configuration
And all worked. I'll wait a short while to see if this fixes the issue. I also have am SA case with MS so will confirm fix when resolved.

Firewalling and NTP (Time) troubleshooting
Hi all. Recently after switching to using a Cisco router (891W, IOS 15.2) instead of a different vendor's router at our site, I began to notice that the time sync on the Windows domain is off. This is causing major domain functionality problems. This is a small business so there is a single domain controller, and it is configured to get time from a source on the Internet.
It's been a while since I set this up on the server so I forget offhand the Internet time server, but the current firewall config for the router matches what I had on the previous non-Cisco router. I'll check into if the Internet time server is th eproblem but those don't tend to go down a lot to my knowledge. The only thing that changed was this router and immediately after is when the problems began.
However in retrospect I wonder if the firewall is even correctly set up. Currently I have udp port 123 open from the outside going to the inside IP of the domain controller on the LAN (using static NAT). But as I think about this, I'm sure that time update traffic is not initiated from the time source (Internet-based time server) but rather by the time client (the domain controller). Please correct me if I'm wrong.
So then with a stateful firewall and provided there are no restrictions from inside to outside for NTP, I should not have to open udp 123 from the outside at all, but instead just allow the inside server to request time from the outside, using whatever dynamic port the firewall allocates.
Is this right? Again, ever since we switched to using the Cisco router, time sync is not working.
Thanks very much.You're thinking is exactly correct. As a test you could also set the router to pull time from the public NTP server and see if it synch's.

Sorry if my attempt to be thorough in my description may result in excessive and unnecessary information.
I'm running into some problems with a single server running WS 2012 R2 as a domain controller (AD and DNS) and I’m trying to figure out what the cause is.
The network has ~10 computers on it connected through a cable business gateway (running DHCP) which feeds 2 switches and a wireless router acting as a switch. (I also turned on remote services, but the end users aren’t using that until I get certificates
setup.)
For 6+ months everyone had access to the shared files and databases on each workstation without issue.
In the last month users would occasionally have to re-enter their credentials to get access to shared server folders despite being on a domain account already.
Last week one of the computers intermittently cannot gain access to the shared folders– entering the correct credentials just results in the credentials being requested again and again: There’s an error icon at the bottom saying that “there are currently
no logon servers available to service the logon request”. While access is rejected I’m still able to ping the DC both via its name and IPV4 address.
(Pinging via its name results in an IPv6 address in the response.)
Other network connectivity appears intact (able to browse the web, perform network discovery.)
Things that ‘seem’ to allow access on this computer until the next failure:
Entering a different domain username and password into the windows credentials request has allowed access a couple of times.
Disconnecting and reconnecting the network cable allowed the original username to be used to log on (at least once.)
After removing it from and then rejoining it to the domain (a few hours ago) it experienced the problem once more. Also, logging on with domain credentials created a TEMP user folder instead of the folder with the domain username.
Looking at the event logs, I notice there are quite a few warnings and errors reported regarding DC access on many of the computers; maybe this is normal?
Most Problematic Computer:
Event ID 8016: System failed to register host A or AAAA resource records. (With an unknown Ipv6 and the server’s ipv4 address in the DNS server list.)
Event ID 131: NtpClient unable to set a domain peer to use as a time source because of DNS resolution error on ‘Server.domain.local’
‘No such host is known.”
Event ID 5719: NETLOGON. This computer was not able to setup a secure session with a domain controller in the domain due …..: there are currently no logon servers available to service the logon request.
And then pairs of: Event 1500: The Group Policy settings for the computer were processed successfully. There were no changes detected since the last successful processing of Group Policy. & Event 1054:
The processing of Group Policy failed. Windows could not obtain the name of a domain controller. This could be caused by a name resolution failure. Verify your Domain Name System (DNS) is configured and working correctly.
Event 1030: The processing of Group Policy failed. Windows attempted to retrieve new Group Policy settings for this user or computer. Look in the details tab for error code and description. Windows will automatically retry this operation
at the next refresh cycle. Computers joined to the domain must have proper name resolution and network connectivity to a domain controller for discovery of new Group Policy objects and settings. An event will be logged when Group Policy is successful.
On the server I’ve run DCDIAG and DCDIAG /test:DNS and those all appeared to pass.

Any thoughts? I was assuming it was a Domain Controller/DNS error, but I don't know where to check next. Could a failing piece of hardware be the culprit?
Thanks,
-JTHi,
According to the error you have posted.
A Netlogon 5719 event indicates that the client component of Netlogon was unable to locate a DC for the domain it was trying to perform an operation against.
Most of the time this is caused by network issues or name resolution (DNS/WINS) issues, you could refer to:

Synchronizing IPCC server's time with an external time source
We have a IPCC server (CRS 4.0.3) running on a Windows Server 2000 SP4 platform. The server is working along with a Callmanager 4.1(3) in a WORKGROUP environment and there’s no domain. The clock on the IPCC server is recently acting very weirdly (back and forth by 10 - 30 minutes!) and I was wondering how can i change the time source provider for IPCC server to use a reliable external time server available on internet (or even use our local router).
Any input on this issue is appreciated in advance!Ok. Let's clear things up.
Problem:
Network Time Protocol service stops in Callmanager 4.1.3 (Windows Server 2000 SP4) after configured to use it's local router as it's upstream time provider as indicated in this document (by configuring "ntp.conf" file): http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_tech_note09186a008009470f.shtml
Here is the error which is loged in windows event viwer:
Time correction of -3619 seconds exceeds sanity limit (1000); set clock manually to the correct UTC time.
Why? 3619 seconds is almost 1 hour but the time on the server and on the router is correct! Could it be something related to DST problem with this box?
Note: DST is not working correctly on this machine and whenever it starts or ends we manually set the clock ahead or behind. We've also left "Automatically adjust clock for daylight saving changes" unchecked due to this problem.
This beahvir of callmanager is causing trouble for our contact center as well because IPCC server is configured to sync it's time from Callmanager using it's own "ntp.conf" file
Any idea? -
Use external drive for both Time Machine and storage for Back to My Mac
Hi all,
I have been "a Mac" now for over a year and just keep finding cool new things that make me happy I switched. The latest thing is Back to My Mac offered with my Mobile Me account. With a rather convoluted mix of PC/Mac/iOS devices to manage - best $99 I ever spent btw...
I also have a 1TB Time Capsule that I have been using with Time Machine to back up all four of my Mac computers at home. Needless to say, the 1TB is really struggling to handle the amount of data being backed up and certainly leaves no room for anything else.
What I wanted to do was to attach a larger external hard drive via a powered hub to the USB port on the Time Capsule and use it for Time Machine backups while using the internal 1TB drive with Back to My Mac so that I can have remote access to all my data from anywhere without having to leave my computer running at home all the time in order for my laptop to "see" it when I'm away. And, yes, the amount of that data far exceeds what any level of Mobile Me subscription can offer! I should also mention that the hard drive is the only USB device connected through the hub to the Time Capsule at the moment. There are no other devices that might be "getting in the way".
I'm thinking maybe all this is asking too much without the addition of a dedicated file server (Mac Mini, perhaps - not a purchase my budget wants to make).
I understand that the Time Capsule doesn't support partitions, so I bought a Western Digital 2TB Elements drive, connected it to my Macbook Pro and used Disk Utility to reformat the drive from the incompatible NTFS it shipped in to a single, Mac OS Extended (Journaled) partition. I then made two folders on the drive, one for Time Machine backups and one for Back to My Mac remote storage/access. Great.
However, when I connected the 2TB drive to my Time Capsule I could not see it at all. Time Capsule was reporting problems in the way of a disk error. From within my Airport Utility, I could see the trouble was the external drive. The utility suggested connecting the drive to a Mac and using it's Disk Utility to troubleshoot.
I followed through, checking the disk, etc. and ended up reformatted the drive on my Macbook Pro yet again with the same specifications as before but without the folders and reconnected it to the Time Capsule. Same deal. But now, I can't even remotely connect to the Time Capsule at all. I can see the Time Capsule in the shared area of my Macbook's Finder but can not connect. The connection tries and fails even before it gets to asking me for username and password credentials.
Long story short, first of all, I suppose I would like to know if I'm asking for the impossible?
Second, if what I want to do *is* possible, what steps do I need to take to make it so?
Thanks in advance for any advice or suggestions you might have.Well, I have now reformatted/partitioned my poor WD Elements 2TB drive about a dozen times as well as restarted my 1TB Time Capsule so many times it's no wonder it's as confused as I am! <G>
Last night, at your suggestion, William, and in respect for your continued support, I tried creating two 1TB Mac OS Extended (Journaled) partitions on the WD external USB drive, both with GUID partition tables. Both volumes mounted to my laptop's desktop flawlessly and without issue.
Once the external drive was connected to the Time Capsule, however, it was a crap shoot as to whether or not the drive was recognized at all, reporting a problem with the disk, or, even at one point, mounting one of the two volumes but not both. <sigh>
I read somewhere on the Internet that you need to restart the Time Capsule for volumes on an external USB drive to be recognized.
So I tried that. I connected the freshly partitioned/formatted disk to the Time Capsule and restarted it. This succeed in removing the issue of reporting a nameless drive with a capacity of 0MB. It then reported the drive with its correct name but would not recognize whatever volumes in whatever partitions that particular crack at it contained with the exception of the once, as I mentioned above, when only one of two volumes mounted correctly and was listed with the right name and capacity on the Time Capusule's Setup's Disk tab.
At this point I have given up on my goal to use the external drive with Time Machine to back up my Macs or to hope I will ever be able to see its contents remotely via Back to My Mac. All I would like to do now is simply find a reason why I can't get it successfully connected and playing nice with my Time Capsule in the first place!
Any further suggestions or advice as to what steps I might take next would be greatly appreciated.
Thank you all. -
I cannot connect my external hard drives any longer. I have one WD "My Passport" used as a Time Capsule and one LaCie Porsche Design used for all different kind of data, formatted in exFAT. They worked fine, connected direct or through an additional USB hub or also attached to a Dell monitor. The Lacie helds my iTunes Library and the iPhoto library.
After I moved the iTunes library to the external drive, from time to time the drive went into a never ending loop and I had to shut down the laptop (MacBook Air).
The last time starting again the drives were not recognized any longer. I tried to connect them to another MacBook, which didn't work.
Starting with Windows 7, the WD is also not recognized at all (perhaps because of time capsule format?) and the LaCie gives an error.
Could anybody tell me if there is a chance to get them alive again? When I connect them now, they start to heat up quite fast without anything else happening.
ThanksHi,
Just want to clarify, have you checked to make sure the cords are not damaged (going from hard drive to computer and or any power source )?
You have also check to make sure that usb ports are working correctly?
If you have checked these things it may be that the external drives have failed.
I would google the error message from the LaCie drive before I do anything.
There are several ways that I know of, one is to put the hard drive in the freezer for a while (make sure you wrap it air tight) if this works it is not a permenint fix. You might be able to transfer information to another source.
The other method is to plug the hard drive into a hard drive connector a product like this:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817707192
to do this you would have to remove the hard drive from its enclosure and still this is not a guarantee it will work.
The finally way I know is using a recovery service. This can be rather expensive, and there are no guarantees -
Using external hard drive on a Time Capsule as a network drive for PCs.
I own a Macbook Air and am using a 2TB Time Capsule router. I am currently using for automatic backups for my Macbook Air.
I also own 2 PC laptops for the rest of the family. Would it be possible to use an external hard drive connected to the USB port of the Time Capsule as a network drive for the PCs? I want to share files between the two PCs.
ThanksYes, you can do that.. although it is not necessarily as straight forward as you might think it should be.
1. The TC has to be running SMB compatible names. short, no spaces, pure alphanumeric.
2. The disk must be formatted to file system the TC can read. HFS+ or Fat32.. but the HFS+ is vastly superior.. the actual format is irrelevant from sharing point of view as it is still shared via SMB to the network.
3. It is slow.. half the speed of the same drive plugged into your computer.. although if the connection is over wireless that is probably irrelevant.
4. You might need a powered hub to get the drive to work.. Apple underpower the USB.. and even a powered disk still won't work.
5. There are some issues with the TC getting the USB drive to work.. too many factors to say you will have issues or not.. but be aware this is not as straight forward as it could be. or should be.
6. If you want to share files.. you can always share them directly.. pc to pc or pc to mac.. there is no necessity to do it via a network store.. You can also use the 2TB internal drive.. create a disk image and you can then store you data in that. Internal drive is much more reliable and faster.

Connecting Ipod and External Hard Drive Source at the Same Time
As I have a laptop computer with limited hard drive space, I connected an external hard drive source to store my music and photos and other non essentials. I received a 5G IPod for Christmas and the only issue I am having is that my IPod will not work if it is connected to my computer at the same time as my external hard drive. This poses a difficulty for me because I do not have the space on my computer to store the music that I would like to add to my IPod. If anyone knows how to resolve this issue, I would be eternally grateful. Please forgive me if this topic has already been addressed.
as of right now this cantb be fixed.... i have the same probelem... we and thousands of other people are going to have to wait until this relase a fix for this probelem... sorry i feel for you
