Exchange Server Restarts Automatically After Configuring Allowed Kerberos Encryption Types

Hi,
Our Exchange 2013 SP1 servers are installed on Windows Server 2012 R2. After configuring "Network security: Configure encryption types allowed for Kerberos" to AES256_HMAC_SHA1
only. The Exchange Servers began rebooting automatically. But after adding RC4_HMAC_MD5, the issue stopped.
Does this means that Exchange 2013 SP1 requires RC4_HMAC_MD5 as an allowed Kerberos encryption type?

this will help you to understand...

  • Notify when managed server restarts automatically after a crash.

    I am trying to see if there is some way I can be notified (by email) when a managed server a cluster restarts automatically. I am running Weblogic 9.2 on Solaris Sparc 5.10.
    I can certainly compare the PIDs of the last and the new JVM but am looking for a slick way to do it especially at the Node Manager level.
    Thanks.

    Hi,
    *The server was started in warning mode and the JTA was declared unhealthy. I saw 2 transaction alive for more than 2000 seconds which is uncommon.
    *The resource adaptor was started properly.
    *We are using file store. But will it make a difference?
    Thanks!

  • How to get Mavericks server that is connected to a UPS to restart automatically after a power outage.

    This is driving me crazy. Is there anyone running Mavericks as a mission critical server on Backup Power Supplies that has a way to get the servers to restart automatically after a power outage. The UPS vendors all have software for Windows, but not Macs, and the setting in System Preferences, doesn't work with the UPS's Iv'e tried (2 different APC models (Smart and Back-UPs), one Triplite (Smart) and one CyberPower, (all claiming to be Mac compatible))

    APC do apparently still do a command-line daemon (PowerChute Network Shutdown) which monitors over the network the UPS and will cleanly shutdown the Mac. For lower-end UPS devices these are typically connected via a USB cable and the built-in Apple System Preferences let you control the options - if it is a model supported. There is however a big limitation of using a USB connection which is that you can only connect a single computer to a UPS via USB and of course most companies have multiple servers.
    It maybe that what is happening even if you use APC's software is the following -
    Power failure detected by UPS
    Signal sent to Mac
    Computer does a clean shutdown
    Power restored
    UPS has no way to tell Mac because it is shutdown and Mac does not support 'Wake on LAN' if fully shutdown
    The Mac does have an option to 'Startup automatically after a power failure'. However this might only take place if the Mac is not cleanly shutdown, it could be that if the Mac is cleanly shutdown it does not count this as a power failure. If this is correct then there is nothing that can be done as users to resolve this, the only way it could be resolved would be if Apple provided a way for a tool like APCs software to both do a clean shutdown and set a flag as this being due to a power failure so that when the Mac does detect the power being restored it triggers the Mac in to booting.
    In the dim and distant past when Macs used ADB to connect keyboards and mice the ADB interface did support an external power-on signal. This does not exist for USB.
    Personally I have regarded the APC software (PowerChute Network Shutdown 3.0.1) to be so badly supported and so old as to be too risky to use. It lists 10.7 and 10.8 but not 10.9 and uses Java 1.6 which itself is unsupported. There is a third-party tool you might want to look at called NUT (Network Ups Tools) see http://www.networkupstools.org
    NUT is free and lets you do clever things like -
    Connect a single computer via serial or USB to the UPS
    Act as a 'server' over the network to other computers sharing the UPS
    When power failure is detected the NUT 'server' sends a signal to the NUT 'clients' so all of them know that there is a power failure and can do their own clean shutdowns
    This gets round only being able to connect a single computer via USB.

  • PI 7.0 Production server restarts automatically

    Hi guys,
    We have installed and configured correctly a PI 7.0 system on Windows 2003 Standard Edition X64-bit with SQL Server 2005. We are on SP12. Everything, SLD, RFC connections work properly.
    The problem is that 4-5 days after the installation the Windows Server restarts automatically in unexpected time during the day (unexpected shutdown), even when anybody doesn't do anything in the system. In the Event Viewer we get the following message/error "System Error: Category 102 EventID 1003". There are no other messages/errors.
    This is a production system and we are supposed to go live within the next days! So I need your help ASAP.
    Any ideas?
    Thank you.
    Best Regards.

    1) update your network card drivers to the latest  and for all devices including your motherboard chipset drivers.
    2) Are you using  ethernet instead of USB?

  • SSRS 2008 R2 Services not restarting automatically after reboot

    SSRS 2008 R2  Reporting instance not restarting automatically after patches install.  Is there a way to resolve the issue
    Windows 2008 R2 Server
    16 GB RAM

    Hi,
    Follow this article to resolve the issue:
    Reporting Services service doesn't start after the installation of MS12-070 security patch
    http://blogs.msdn.com/b/mariae/archive/2012/11/12/reporting-services-service-doesn-t-start-after-the-installation-of-ms12-070-security-patch.aspx
    Workaround 1:
    Modify the registry to increase the default time-out value for the service control manager. To increase this value to 60 seconds, follow these steps:
    1. Click Start, click Run, type regedit,and then click OK.
    2. Locate and then click the following registry subkey:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control.
    3.  In the right pane, locate the ServicesPipeTimeout entry.
    Note If the ServicesPipeTimeout entry does not exist, you must créate it. To do this, follow these steps:
    a.On the Edit menu, point to New, and then click DWORD Value.
    b.Type ServicesPipeTimeout, and then press ENTER.
    c.Right-click ServicesPipeTimeout, and then click Modify.
    d.Click Decimal, type 60000, and then click OK.
    This value represents the time in milliseconds before
    Restart the computer for the changes to take effect. Check that SSRS services can be started now.
    You cannot start SQL Server Reporting Services after you apply the update that is discussed in KB 2677070

  • Exchange server 2003 restartштп, after DC shutdown

    We have Exchange server 2003 and two DC on server 2008 r2 in organization.
    When main DC is shutting down, exchange server restarting. There are no scrips\GPO that orders to restart Exchange after shutting down the DC.
    What can cause this occurrence? How can I fix it?

    Hello,
    to work correct with Windows server 2008 r2 DCs it is important that Exchange 2003 SP2 is installed.
    Beside this you may create an additional GC in the ESM Recipient update service fo the second GC, so the connection is still available.
    We are also running Exchange 2003 with multiple Windows server 2008 R2 machine without any problems.

    my iphone 5 crashes (restarts) automatically after updating to ios 7.1 anyboday facing same issues ? Need help !!!!

    I am having the same issues--just got off phone with customer service rep--was told that my phone is in recoveyr mode and that I would have to restore it, however, the only things that would be restored would be from my last backup which was in November 2013!  I was also told that apple users should not update as soon as the update is available (so why are they sending it to us if they're not sure that there will be any problems!!!).  I can't restore now since I am in work--will do it when I go home tonight.  In the meantime, I am without a working iphone for the day!  This is horrible--I see I'm not the only one who has experienced this!

    Hi,
    I have followed above already the problem remain same.
    I have disabled Microsoft Exchange Health
    Manager Service to monitor till now issue not reported.
    Is this best practice to disable the service in these kinds of issues or is there any other way?
    Its a workaround that many have used yes.
    However, having said that, its not something you want to leave in place.
    I would suggest upgrading to at least CU6 or CU7 and if that does not resolve the issue, opening a support case with Microsoft.

  • Some Systems Restarted Automatically after Updates Deployment with Restart Suppressed

    I've searched the forum and multiple blogs - but, I'm still confused about what is causing some of our workstations to restart after applying a software updates deployment.
    I deployed the Dec 2013 Patch Tuesday updates to a collection of workstations. The deployment was set to:
    Not allow restarts outside of a maintenance window (box is unchecked)
    Suppress restarts on workstations (box is checked).
    There is no maintenance window defined for any of our workstations
    On all the workstations, the HKEY_LOCAL_MACHINE\Software\...\WindowsUpdate\  values are:
    WUServer: http address of our SCCM SUP server
    WUStatusServer: http address of our SCCM SUP server
    Also, the key in HKEY_LOCAL_MACHINE\...\WindowsUPDATE\AU is:
    UseWUServer: 1  (which I understand disables the use of the automatic Windows update service)
    Some set of workstations automatically restarted shortly after 3:00 am the next morning. Clearly that's the Windows Update Agent jumping in a restarting the systems. However, I don't understand why it would do that. I really don't understand why it would
    have occurred on only some of the workstations while others are still waiting for users to manually restart 36 hours later.
    All of the workstations are in the same active directory OU - so the same set of GPOs applies to all.
    Note: none of the registry keys were set directly in any GPOs - I assume the values were set by the SCCM client.
    Any assistance would be appreciated.
