Windows Server 2012R2 - svchost.exe 60-100% load!

We are using RDS collection with two Windows Server 2012R2 session hosts. Both hosts are virtual servers (clean installation) and are used as session hosts (terminals) with 10 to 25 users each. RDS Connection Broker is also virtual machine with Windows
Server 2012 R2. Our users are using Windows 7 Embedded thin clients with MSTSC RDP 8.0.
There is problem with high cpu load on these servers. Sometimes Svchost.exe starts to cause 60-100% load. Our virtual machines have 10 virtual processor cores. Load is caused by LSM (Local Session Manager) Service from DCOM Launcher group. Svchost
creates many thread as you can see on picture attached. Sometimes this load disappears after 12-24 hours, sometimes it needs restarting whole server.
We still cannot find cause of this problem, although we managed to reproduce this issue one time by logging two admin accounts to server console and force disconnecting one of these accounts by third admin account connecting to server console by RDP
mstsc.exe with -admin parameter.
Our users are very unsatisfied :-(
This is screenshot of Process Explorer - svchost.exe - Threads:

Hi,
Thank you for posting in Windows Server Forum.
Do you have any recent updates, might happens due to automatic updates which also can cause high cpu through svchost.exe. Please check as suggested by “Larry” by turning off Windows update service. In addition go through beneath articles for more information.
1. Automatic Update causes SVCHOST.exe high CPU
2. Getting Started with SVCHOST.EXE Troubleshooting
Hope it helps!

Windows Server 2012R2 DHCP Load Sharing Mode

Hello,
I am planning to migrate a standalone DHCP Server on Windows 2003 to Windows Server 2012R2. With this migration, I like to use the 2012R2 Load Sharing Mode feature for DHCP. This implementation cover TWO sites.
My initial plan was to have two Windows 2012R2 DHCP Servers (virtual) at each site thus servers at each offers site redundancy as well. So two at Site 1 and two at Site 2 on load sharing mode. If ServerA at Site 1 goes down for some reason Server B
at Site1 will service the DHCP clients in load sharing mode without going to Site 2. I came across a MS document that says:
Number of Servers: DHCP failover is not supported for more than two DHCP Servers. The failover relationship is always comprised of two DHCP servers.
Does this mean I can have only TWO DHCP Servers in a load sharing mode. One at Site 1 and the second one at Site 2??
Thanks in advance
TIA TP

Hi,
The DHCP failover relationship is comprised of DHCP server and its partner. In a relationship there are just 2 DHCP servers.
But this doesn’t mean you can just use 2 DHCP servers in your sites. The DHCP failover setting is based on DHCP scope, for one DHCP scope there could be just one DHCP failover relationship including 2 DHCP servers. If you have more than 1 DHCP scope,
for example, set DHCP failover relationship between DHCP server 1 and DHCP server 2 for scope A. then set DHCP failover relationship between DHCP server 1 and DHCP server 3 for scope B.
The document Step-by-Step: Configure DHCP for Failover(http://technet.microsoft.com/en-us/library/hh831385.aspx) is a introduction about this function and for your reference.
Depends on the DHCP scope’s configuration and the requirements of your network. You may enhance or customize the architecture of implementation.

Can't create ODBC connection in Windows Server 2012R2

I just finished installing the instant client & odbc connection on Windows Server 2008R2. I then attempted to perform the same installation on a new Windows Server 2012R2 instance and encountered the following issue.
After extracting the contents of the 64bit instant client & odbc files into c:\oracle\instantclient_12_1, adding this to the path statement, and adding a TNS_ADMIN environmental variable, I successfully ran odbc_install.exe from an admin cmd window. I then opened the 64bit ODBC Data Source Administrator, clicked add, selected the Oracle in instantclient_12_1, and clicked finish. As soon as I did so, I received the following error: "The setup routines for the Oracle in instantclient_12_1 ODBC driver could not be loaded due to system error code 126: The specified module could not be found. (c:\oracle\instantclient_12_1\SQORAS32.dll)"
I uninstalled the odbc client (odbc_uninstall.exe) and attempted again with the 32bit version & 32bit odbc configuration screen. I get the exact same result with 32bit as I do with 64bit.
Any help would be appreciated.
EDIT: Nevermind. Apparently I needed the Microsoft Visual C++ 2010 SP1 Redistributable Package for the correct DLLs

Hi,
I am running Netweaver 7 and ERP2005.
J2EE support pack is 9. The sap note that you mentioned is for NW2004 and our system is running on NW2004s.

Hi Gopi,
Are you trying to add the hosts to your OEM 12c, and then choosing "Deploy Agent"?
Please check this error message about the image file..
The image file C:\oracle\core\12.1.0.2.0\jdk\bin\java.exe is valid, but is for a
machine type other than the current machine.
"Validating OMS_HOST & EM_UPLOAD_PORT failed."
If the agents are deployed earlier from another OEM12c server, please undeploy them and then try.
Thanks,
Rajiv.

Windows Server 2012R2 Failover Cluster error with mounted volumes

Hi all,
I've a problem with mounted volume on a WSFC build on top of Windows Server 2012R2, the situation is:
M: is the volume hosting mounting points
disk-1, disk-2, disk-3 are volume mounted on M:\SomeFolder
Theese volumes are used by a SQL Server Failover Cluster Instance, but my problem is related to WSFC. I've set dependencies so disk-1, disk-2, disk-3 depend upon H:
If I try a failover of the role "SQL Server" I observe that when the disk come online in the other node they fail with this error:
Cluster resource 'disk-1' of type 'Physical Disk' in clustered role 'SQL Server (ISQL2014A)' failed. The error code was '0xaa' ('The requested resource is in use.').
Based on the failure policies for the resource and role, the cluster service may try to bring the resource online on this node or move the group to another node of the cluster and then restart it. Check the resource and group state using Failover Cluster
Manager or the Get-ClusterResource Windows PowerShell cmdlet.
If I manually take offline H: and than bring it online and then manually take online all disk (1 to 3) they come online with no error.
I'm going crazy!

I've found the root of the problem: the servers are virtual machine on a VMware ESX 5.5 infrastructure, VMware claims that on 5.5 multipath is supported for raw device mapping disks but disabling multipath (I've set to fixed path) the Windows Server Failover
Cluster stops to get problems.
Now we have opened a support call with VMware.

Installing MS Exchange on Windows Server 2012R2 Essentials?

Hi Guys,
I am having trouble finding the appropriate answer to my question - is it possible to install MS Exchange 2013 on Windows Server 2012R2 Essentials edition? Needless to say that this server will be a DC as well - I am aware that it is ot recommended to install
Exchange on domain controller but that is not my question here. I just need to know if it can be installed on 2012R2 Essetials edition? Thank you.
Dino

No. I'm not aware of any documentation showing how this can be done.
Too complicated, the sharing of the IIS the needed ARR..... not supported...not recommended. You get the idea.
That ship has sailed.
Unfortunately TechNet subscriptions aren't coming back, sorry folks :-(

Some Word Files will not open on Windows Server 2012R2

I have identical versions of Word 2010 on two different computers. One is Windows 7, and one is Windows Server 2012R2. The Win 7 is my primary writing machine but sometimes I need to open a Word file on the other machine.
Some of the files open fine on Windows2012 machine, but some give me an error:
"Word experienced an error trying to open the file." It then makes some suggestions for things to try, including Repair as I am opening the file, but none of these suggestions work. I keep getting the same error.
I cannot see what is different between the files that open fine and the files that give this error.
They all open fine on the Windows 7 machine.
I have tried do a full Repair on Microsoft Office and then rebooting.
The normal way of sharing the files is to copy from Windows 7 to a cloud location and then downloading on the Windows 2012 machine. But I have also tried emailing the file to myself from Windows 7 and opening the email on Windows 2102. I get the same problem.
What else can I try?
Thanks

Re activate windows server 2012r2

I have activated windows server 2012r2 and after the Tuesday morning update the server states that I need to activate again.Microsoft support want's $500.00 to fix the problem. There has to be a way to deactivate and then re-activate.

If you have valid key, then it should not be a problem. Have a look at this : http://its.virginia.edu/software/mslicenses/activate.html

We're running Windows server 2003 32bit and want to migrate to Windows server 2012R2 64bit, can someone provide a step by step procedure on how to migrate instances on ADAM to AD LDS?

I have no experience in dealing with servers, but my senior has asked me to investigate on how to migrate instances on ADAM (windows server 2003 32bit) to AD LDS (Windows server 2012R2 64 bit) as in place upgrade is not an option as we're running a 32bit
Server and want to migrate to a 64bit Server. can someone please give me a Walkthrough on how to do this.
Thanks in advance.

Hi,
it'd be of great help if you could give me a step by step process of replication.
There is no step-by-step article/guide of replication process, replication between AD LDS instances of the same configuration set is an automatic process.
All we need to make sure is to create a replica of the existing instance, and there is no network/security obstacle preventing the replication.
Please note that we need to install AD LDS from Server manager on Windows Server 2012 and 2012 R2.
More information for you:

How to Migrate windows 2008r2 RDS server to Windows server 2012r2 RDS

Hi, I want to migrate our 2008r2 RD server + Cals to windows server 2012r2 server, the user will still connect to 2008r2 server but the server hosting the license will be migrated to a 2012r2 server. Currently I have 2 servers that users can connect
to that are served by the 2008r2 RDS (the server I'm converting is just hosting the license) the server user connect to point to this license server. How do I proceed to migrate, I'm searching for documentation but I can't find much, I found that I can only
convert to 2012r2 from 2012 or better OS, so I installing a temporary 2012 server to do a double migration seem to be the best course of action but I can't find any documentation on how to Migrate the Remote Desktop Services Role Services from 2008r2 to Windows
Server 2012.
Also I just discovered that this server is also hosting license for windows server 2003 terminal service. Will I be able to host these licences on 2012R2 ?
Any pointer would be appreciated.

Hi,
It seems like migration the Remote Desktop Services Role Services from 2008r2 to Windows Server 2012 is not supported.
http://technet.microsoft.com/library/dn479239.aspx
So i think you may install and configure the RDS server on Windows Server 2012 and then migration to Windows Server 2012r2.
Hope this helps.

Windows Server 2012R2 disks go offline after reboot

Hi all,
I've a strange issue in my brand new Windows Server 2012R2, let's describe the environment:
Hypervisor = VMware ESX 5.5
Guest OS = Windows 2012 R2 Standard Edition
I've configured the guest OS with several disk for a SQL Server installation, each disk are presented as "pure" virtual disk to Windows that means no RDM (pass through disk).
After a reboot I've discovered that SQL Server has failed to come online, on a brief analisys, all the disks except system drive (C:) and a volume dedicated to swap file (D:) have not come online. They are present in disk management, but they are offline.
I've manually brung online those disk, than reboot and all returned to normality. Subsequent reboot have generated no issues.
In the system log I have no error message except that one of SQL that fails to came online due to the lack of disks...

This happened to me too. Except with server 2008 R2 and exchange 2010. My servers replicate offsite using zerto and I was testing failover and noticed the drive D was offline. Brought it online then rebooted and everything was fine.
So I just build a server 2012 R2 Datacenter edition VM on my production servers, gave it a second disk, initialized it, formatted it and assigned it the drive letter D. Rebooted after installing 3 windows updates and it was offline. There is nothing on this
server at all. It's a fresh install.
I'm running ESXi 5.5 build 2302651 with hardware version 8 and VMware tools version 9.4.11 build 2400950.
From my experience when you see this kind of stuff happen in multiple situations it will happen again. My worry is what if one of my hosts decides to die and HA kicks in and the disk is offline when it boots.
Anyone have anything to add to this?
Edit: My DR site where I tested my failover is DAS and my production site is iscsi. So I don't think the storage type matters.
Edit 2: The SCSI controller type is Paravirtual for all my VM's.

Windows Server 2012R2 kerberos authetication failure with IBM iSeries

Hi all,
I've an IBM iSeries in my environment configured to use kerberos authentication, this type of SSO works fine from 2 years. Every client Windows 7 or Windows 8 works fine.
Now I'm planning to deploy Windows 8.1 and Windows Server 2012R2.
I've made a lot of attempts:
Windows 2012 -> works
Windows 8 -> works
Windows 2012R2 -> does not works
Windows 8.1 -> does not works
All the server and workstation involved in thees attempts belong to the same OU and the same user are utilized.
It seems clear to me that Windows 8.1 / 2012R2 has a different behaviour with kerberos authentication but I don't found anything on the technet.
Please note that all DC are Windows server 2008R2 by two years.

Hi, any news for your problem ?
This setup should work ok.. Any firewall running on the 2012R2 or 8.1 ? did you checked the security log on the DC to see why the ticket was refused ? etc..

Windows Server 2012R2 RDS sound and smartcard redirection issues

We are using RDS collection with two Windows Server 2012R2 session hosts. Both hosts are virtual servers (clean installation) and are used as session hosts (terminals) with 10 to 25 users each. RDS Connection Broker is also virtual machine with
Windows Server 2012 R2. Our users are using Windows 7 Embedded thin clients with MSTSC RDP 8.0.
Our terminals are running correctly after fresh boot, but in 12 to 48 hours after boot we encounter problem with sound and smardcards redirection in RDP. Remote sound stops working and users cannot login with their smardcards.
Relogging users doesnt help, deleting profiles doesnt help, restarting sound service doesnt help, only viable way to solve issue is server restart. There is not any event in event log about this issue.

Hi,
Thank you for posting in Windows Server Forum.
Sound Redirection:
Please check the following GP setting as well.
Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Device and Resource Redirection
Limit audio playback quality: Enabled
Audio Quality: High
On the Client PC, in the .rdp file that you use to connect to the server, make sure you have the following line:
audioqualitymode:i:2
In addition check that the Windows Audio and Windows Audio Endpoint Builder services must be running for audio to work.
Smartcard redirection:
Kindly try to update the patch for Smartcard redirection and check the result.
