SCOM 2012 SP1,More than 5 asynchronous responses generates Event ID 21410

On the RMS use RegEdit to navigate to

HKEY_LOCAL_MACHINE\Software\Microsoft\Microsoft Operations Manager\3.0\Modules

Under this key create a new subkey called Global

Under the new Global subkey create another subkey called Command Executer Under the Command Executer subkey

create a new DWORD value AsyncProcessLimit

For the value of AsyncProcessLimit you can set a minimum of 0x00000001 (Strongly not recommended)

and a maximum of 0x00000064 (100)

(again definitely not recommended).

So, if you wanted to increase the number of async command notifications from 5 to 10 the key would look like:

HKEY_LOCAL_MACHINE\Software\Microsoft\Microsoft Operations Manager\3.0\Modules\Global\Command Executer\AsyncProcessLimit

REG_DWORD:0x0000000a

檔案總管，圖片檔案無法顯示縮圖

無法顯示縮圖

有時，也不曉得有人是怎麼搞的，在檔案總管裡的圖片檔案忽然就沒有辦法預覽圖片，無論是切換到大圖示、中圖示，甚至是特大圖示，就都沒有辦法顯示出圖片的縮圖

會發生這種情況，我想可能就是安裝或是移除了一些看圖軟體所導致，通常這些看圖軟體在安裝時，一定都會修改了Windows的設定值，所以在移除時，萬一它沒有將設定值修改回來，或是移除到一半失敗時，大概就會發生這種類似的問題。
而針對無法顯示縮圖的狀況的解決方法如下。

Step 1. 開啟任何一個資料夾，點擊左上角的「版面配置」，並從下拉式功能表中選擇「資料夾和搜尋選項」。

Step 2. 跳出「資料夾選項」對話盒後，切換到「檢視」頁籤，接著取消勾選「一律顯示圖示，不顯示縮圖」的選項，最後再點擊〔確定〕即可。

Device manager and network connections window blank

Cause

=======
This issue would occur if the default permissions on the following key go missing: HKLM\System\CurrentControlSet\Enum\Root

The default permissions are as follows,

• Creator owner – Full permission.
• Everyone- Read only.
• System Account – Full permission.

Resolution
========
Open the registry editor and add back the above mentioned permission to the HKLM\System\CurrentControlSet\Enum\Root  key and then reboot the server.

Export SCOM Overrides

## You’ll need to run the script from within a SCOM console or load the SCOM Powershell module.

#define the path you want to export the CSV files to
$exportpath = "c:\admin\"

$mps = get-managementpack | where {$_.displayname -eq "Overrides.Microsoft.Exchange.2010"}

Hyper-V Installation Network Settings Reset

Cause

=======
This issue occurred because of the SR-IOV feature enabled in the server's BIOS.

With certain HP hardware/drivers, this causes re-enumeration of the PCI devices when Hyper-V Role is installed.

Solution

========

To resolve the issue, the following steps can be performed:

A. Disable SR-IOV from HP's BIOS:

To disable SR-IOV in the UEFI ROM, complete the following steps:

1. During system boot, press F9 to run the System Utility.

2. Select System Configuration, and then press Enter.

3. Select BIOS/Platform Configuration (RBSU), and then press Enter.

4. Select Advanced Options, and then press Enter.

5. Select Advanced System ROM Options, and then press Enter.

6. Select SR-IOV, and then press Enter.

7. Select Disable, and then press Enter.

8. Press F10 to save.

B. Configure the NIC teaming and all other relevant configuration as required.

C. Install Hyper-V role and reboot.
