Time Sync registry key in DHCP Failover...

Hi all;
As you know, the check for time sync is based on the registry value configured for permissible time difference. Can anyone know where this registry value?
Thanks

How to include install date and time in registry keys

Hi All,
Hopefully someone can help me. I am creating an installer which includes some properties in the build specs. I also wannt to include some registry keys to be added upon installation:
1. I include the install directory of the application by providing the key with the value [INSTALLDIR]. This seems to work well and I have no problem with this.
2. The other key I would like to include (but I do not know how) is the date and time of installation. Is there a way of automatically including this in a registry key (similar to INSTALLDIR)?
I look forward to your expert advice!
Kind Regards,
Larry

Larry,
afaik the setting for "Run as Admin" is per OS process. As the "Run Exe after installation" is a different process as the application you installed by it (e.g. "MyApplication.exe"), i wouldn't expect the MyApplication.exe to require/use admin-rights.

How to disable Quick Time in registry key?

My organization with windows 7, server 2003 and server 2008 and have install Apple Quick Time Player 7.74.80.86 for over 100,000 machines. Can you advice any registry key to disable auto update so that I can use PowerShell Script push to all the machines?

But when I swipe down RIGHT when I get a text message, the notification tells me to reply right away. I don't want that. Is there a way to turn off this feature?

Time Sync - DHCP Failover - 1 minute difference - How to avoid problems?

I have 2 WIn2012R2 servers with DHCP installed, domain members and clocks synched via AD normal operation
I´ve configured the first DHCP Server and i´m worried about a possible problem, because the DHCP Servers have to be, almost-perfect time sync to operate properly
Can I configure a scheduled task to regularly force the time sync ?
If yes, using "net time" or "w32tm"?
"...If the time difference between the servers is greater than one minute, the failover setup process will halt with a critical error
instructing the administrator to synchronize the time on the servers...."
http://technet.microsoft.com/en-us/library/hh831385.aspx

Well the built-in sync mechanism should be enough. Most of the time, as long as the machines have the same time source (DCs in your case) they shouldn't drift more than one minute apart.
You can use w32tm /monitor /computers:<dhcp1>,<dhcp2> to verify the current time synchronisation remotely. Or even w32tm /stripchart if you want to see something more graphic with the current offset on the servers.
Ultimately, w32tm /resync is the way to force sync.
Why not
enabling the log on the w32tm service for couple of days/weeks and check if you see anything wrong?
Are they virtual machines? If no, nothing to add :)

DHCP Failover Auto Config Sync

Downloaded most current version of script and set it up in lab. It works but the log file (.\dhcpautosynclogfile.txt) is growing at a fast rate. Entries for sync complete and automatically sync again are being posted at rate of 3 or 4
times per second.

Script is the DHCP Failover Auto Config Sync script.
Questions is - why is log file filling at such an alarming rate ?
And what script is that? Who wrote it? Have you contacted the author?
Believe it or not, we haven't heard of every script ever written. =]
EDIT: Is this what you're referring to?

The timer service encountered an exception checking for the upgrade mode registry key. Requested registry access is not allowed.

Once in a while i get the error
Event ID 6463
The timer service encountered an exception checking for the upgrade mode registry key. Requested registry access is not allowed.
This also happens when i restart the timer service.
I already cleared the SharePoint cache (xml's) but no success with that.
Environment is
SharePoint 2013 SP1 + CU Dec 2014

This is a brand new SP13 with SP1 installation after binaries installation i also installed Dec 2014 CU and then created the SP farm.
The Apppool/Timer account is member of WSS_ADMIN_WPG.
Issue can be reproduced with restarting SharePoint Timer Service.

Client Authentication/Authorization via ISE & AD, Posture Registry Key, and mapped to specific DHCP scope by AD membership

Hi Team,
I'm currently working on a configuration entailing WLC and ISE where the customer wants a single SSID,and wants his wireless clients to authenticate successfully if they pass a registry key compliance. Additionally, they want clients to received a different IP address or get mapped to a different DHCP scope based on the Microsoft AD group they belong too. for example:
Client authenticating with registry key and in AD group ABC that passes authentication gets IP address or subnet for AD group ABC.
Client authenticating with registry key and in AD group XXX that passes authentication gets IP address or subnet for AD group XXX.
Clients---->WLC------>ISE-----> MS AD ( groups ABC, XXXX, YYY )
currently using EAP-PEAP/MSCHAPv2
Does anyone have any idea or pointers or can refer me somewhere that I can read on how to accomplish this? Not sure on how to do the registry compliance check nor what attributes will allow me to map the client to a DHCP Scope based on this AD group membership?
Thanks...

Open Registry Key VI. Error -604. But just under Run Time Engine (RTE) when no admin rights

Hi,
When I run my code under RTE I'm getting -604 error saying remote access to registry denied.
To make it work I have to grant admin rights to the user, and then I can run my code under RTE.
The problem doesn't exist under Development Environment. The user can have no admin rights to be able access the registry.
OS: Win7 x32
Any suggestions?

Well in the RTE it's an executable so I expect UAC has a look at what the exe tries to do. Also...are you running the development environment on an account with administrator privileges / UAC turned off? (I do development on a PC with local admin rights....and/or when LV installs it requests to always run with elevated privleges).
I think there is a way to get an application to declare it needs elevated privileges at install/run-time somehow but I never really figured out how to do this.
(Because to install the software you need admin rights so while installing it can do other things...which is why you can set registry keys in your installer)

How to test Windows 2012 R2 DHCP Failover without shutting down the service?

How can I test the Win2012R2 DHCP Failover?
There is a command or script, that i could use to test if DHCP failover is working properly?
How to monitor the sync of the objects?
How to make sure that it will do the job, if required?
Or i have to really stop DHCP server main server and see the failover?

Hello,
you have to keep in mind that this has ONLY effect for machines that request during the downtime a lease. So if your lease time is for example 8 hours a computer will ask after 4 hours for the renewal of the lease.
Means there is no problem for running machines during the test. You just need a computer to start after the service is shutdown on the first DHCP server, should take only some minutes to check if the fail over works. Then you could already start the service
again if you see the lease on the new server.

GI time sync question

Oracle 11g grid infrastructure install guides clearly say that if I use a time sync service other than CTSS (like Windows time service or NTP), then I must prevent backward time adjustment on all nodes of the cluster. This is done by registry key on Windows or adding -x option to NTP on Linux.
Doing so results in a problem. The time on many nodes of the cluster is running ahead of the standard time source and cannot be synchronized backwards. The net result is that the time on all nodes is out of sync by 30-40 seconds. In few more months, the time will be ahead by several minutes on several ndoes. Our server admins are getting errors in server logs because the time cannot be synchronized. I cannot find any recommendation or best practice document from Oracle on how to correct this situation unless the time on some nodes is adjusted backwards. Any ideas?
Thanks...
Arun

If I bring time forward on all servers, very soon, the servers will be way ahead of the actual time. Also, if I have to manually keep the time in sync, then why use time synchronization in first place??
We do use an external server but I am not sure which one. We want to keep the server time in sync with a standard time source. The requirement that time cannot adjusted backwards makes it impossible to do so.
Thanks...
Arun

CRIO 9076 Time Sync

If this is true NTP synchronization does a large correction of the date-time on boot. After boot, it adjusts the processor clock to account for drift. The algorithm has an error tolerance but if you exceed that tolerance (i.e. if you are too far out of synch) it will stop trying to adjust the processor clock to synchronize. Calling the Set Date & Time VI typically causes the clock to move beyond the algorithm error tolerance. Is there an error tolerance on the large correction also? I am not able to get my system to sync on boot so if the controller resets, I lose my time. Is there a VI to query the sntp server during initialization and set the time there?
Solved!
Go to Solution.

I must be doing something wrong then.
I have a PC and the crio in a mini switch which is connected to out network switch so they are both running through the same network gateway.
Our Time Server is the same machine as our DHCP server and the DHCP is providing an appropriate IP.
On the Web Based config page of the crio I am getting "Failed to Receive Response from SNTP server" at the 60 second polling interval.
I have installed NI-TimeSync 1.1.2 on the cRIO. Below is my ni-rt.ini

Registry key CurrentVersion incorrect and cannot find java.dll

I have been reading the posts in this forum related to similar errors but not quite sure that they address this situation. Here is what I am seeing:
I have j2sdk 1.4.2_05 on WindowsXP and the HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\CurrentVersion has the value 1.4.2_05. The j2sdk install copied the java.exe to C:\j2sdk1.4.2_05\bin, C:\j2sdk1.4.2_05\jre\bin and C:\Program Files\Java\j2re1.4.2_05\bin folders. It also copied the same file to the windows\system32 folder. So far so good.
In my windows PATH env. variable, the windows\system32 path comes first . So when on the DOS prompt, I type "java -version" or even "C:\windows\system32\java -version", I get the following error :
Registry key 'Software\JavaSoft\Java Runtime Environment\CurrentVersion'
has value '1.4.2_05', but '1.4' is required.
Error: could not find java.dll
Error: could not find Java 2 Runtime Environment.
However, running
C:\j2sdk1.4.2_05\bin\java -version OR
C:\j2sdk1.4.2_05\jre\bin\java -version OR
"C:\Program Files\Java\j2re1.4.2_05\bin\java" -version
works and I get the version info for 1.4.2 j2sdk.
Now I know that prefixing j2sdk bin path to the PATH variable, so that it comes before windows\system32 will set it right. But I think I should not have to do that , if the j2sdk installation has already copied the latest java.exe to the windows\system32 folder. If it was just an issue of java.exe in windows\system32 being in sync with the JRE current version in registry, I think even just "java -version" should have worked. Since that is not working, maybe there is something beyond that. At this time, I do not know what that could be.
Any suggestions?

The java.exe file in system32 that's being executed isn't version 1.4.2_05. Either you have multiple copies of java installed, or the install got screwed up.
Check version and (maybe) just copy the correct file into system32?

Windows 2012 DHCP Failover "Lost contact with partner"

We have stood up a pair of Windows 2012 DHCP servers and configured DHCP failover (in Load Balancing mode) as per the Microsoft Technet article. The two servers are on the same subnet, and time is in sync between them. Almost immediately after
configuring scopes to failover, one node loses contact with the other, and the alternate node goes to failover mode "Recover".
We have restarted both servers and services. Both DHCP servers show as available. Clicking "Replicate Failover Scopes" completes successfully with no errors, and the only two warnings in the Event Log are about credentials for Dynamic
DNS updates and a dynamic IPv6 address (which we don't use at all.)
How come they can replicate, but have "lost contact"; and how do we get the one out of "Recover" mode?

You should see Recover state only if one of the DHCP server actually went down and came back up. In this case the server which comes back up would be in Recover state but will transition to Recover_Wait state and come back to Normal after it syncs it
leases. This should be relatively quickly. Did your servers continue to remain in the Lost Contact...\Recover state for long.
Did you see any events in the DHCP Server admin channel
Microsoft\Windows\DHCP Server\Admin.
You can also enable AuditLogs (Microsoft\Windows\DHCP
Server\AuditLogs) which logs all the server to server messages. You can enable the log by right clicking on
Microsoft\Windows\DHCP Server. View->Show Analytical and Debug Logs. This will show the
Microsoft\Windows\DHCP Server\AuditLogs in event viewer. You can then right click and enable the log and see if there are any failures
being logged there.

"Error while registering the Java 2 Runtime Environment registry keys"

"Error while registering the Java 2 Runtime Environment registry keys"
I am getting the above error when trying to install the 1.3 JRE (installed with the 1.3 plug in which I need). As part of my development I have been installing and uninstalling the JRE multiple times. Then, I got the above error when trying to install it, and now it appears to be installed but I cannot uninstall it. When I try to uninstall it, it just remains, and when I try to install it again I get the above error. I have tried cleaning up all javasoft registry entries, but it doesnt seem to have helped. Can anyone help me either completely uninstall the JRE so I can do a clean install or help me get rid of the error above when I install. Is there some registry entries I should be looking at? Anything else? this is quite urgent as I need to test my applet with the plugin installed and not installed - and I currently cant uninstall it. Any ideas?
Thanks for your help

I am getting this same error message when trying to upgrade from 1.3.1_03 to 1.3.1_19.
I have multiple versions of jre's and jdks on my machine.
Anyone else seen this problem or know how to resolve it.

I can not re-install/ update apple iTunes on my HP PC running Win7-64. I get a registry key error when installing and am asked to make sure I have access. IT is a home PC with one user and I have admin priveledges.

When the updater notified me of an iTunes update, I selected the update option. The update failed and killed the version I was running. I have tried for a year to fix the problem without sucess. I can't completely remove all Apple products. I can not install any apple products especially iTunes which is the only one I am interested in.
When I install iTunes now I get a registry key error similar to this:
I am using a machine where I am the only user and am the Admin. I have looked at the security settings on this key and see nothing wrond with it or the parent keys. I tried removing all apple products but ran into similar problems. At this time I still have Bonjour. Mobile Device Support, Software Update, and Application Support installed.

These ones are tricky. But the following instructions are worth a try.
First do a complete uninstall of iTunes and related components (but don't reinstall just yet), as per the following document:
Removing and reinstalling iTunes, QuickTime, and other software components for Windows Vista or Windows 7
a. Launch regedit (Start >> Search Programs and Files >> type Regedit and open the regedit that comes up.)
b. Access the following Location: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData \S-1-5-18\Components
c. Perform the following actions
i. Right Click on Components Folder
ii. Select Permissions
iii. Select Full Control and Read Permissions options
iv. Select Advanced Button
v. Select Owner Tab
vi. Select to Change Owner to the Administrators
vii. Check the option “Replace owner on subcontainers and objects”
viii. Select OK when prompted that it may not change all.
ix. Select Apply
x. Select Apply again
xi. Exit the Registry Editor
Now try reinstalling iTunes again. Does it go in properly this time?
