为什么对OCS服务器的远程WMI调用失败？ [英] Why do the Remote WMI calls to OCS Server fails?

问题描述

为什么对OCS R2服务器的远程WMI调用失败？ （详情如下）。我错过了OCS服务器上的任何设置吗？

< font face = Calibri>

我正在尝试从远程PC读取MSFT_SIPTrustedAddInServiceSetting的实例请求失败并出现Win32错误"发生了操作错误。"。我试图读取大多数OCS R2提供程序类并获得相同的错误，同时我能够读取系统提供的类（MSFT_Providers工作正常）。在'OCS R2系统'（本地WMI）上尝试此操作时，它运行良好。

设置：

· < font face = Calibri>'OCS R2系统'和'WMI客户端PC'在同一个域中，'WMI客户端PC'登录，域用户是'OCS R2系统'的本地管理员

· 我使用的工具'wbemtest'和'WMI CIM Studio'尝试上述操作

· 还写了一个WMI客户端应用程序在下面的步骤5中失败

1。 CoInitializeSecurity

2. CoCreateInstance（IWbemLocator）

3. < span style ="font：7pt'Times New Roman'"> IWbemLocator-> ConnectServer（OCS服务器，OCS管理员用户，密码， ...，IWbeServices）

4. IWbemServices-> ExecuteQuery（WQL，"Select * from MSFT_SIPTrustedAddInServiceSetting"，...，IEnumWbemClassObject）

5. IEnumWbemClassObject-> Next（......，IWbemClassObject）

6. IWbemClassObject-> Get （PropertyName，PropertyValue）

解决方案

我有他完全相同的问题，在安装了OCS R2的主机上一切正常，但从远程PC访问WMI会出现以下异常。

（HRESULT异常：0x80072020）
/> at System.Runtime.InteropServices.Marshal.ThrowExceptionForHRInternal（Int32 errorCode，IntPtr errorInfo）
at System.Management.ManagementObjectCollection.ManagementObjectEnumerator.MoveNext（）
at System.Management.ManagementObjectCollection.get_Count（）

string wmiQuery = " SELECT * FROM MSFT_SIPTrustedAddInServiceSetting WHERE TYPE = \" ;" + name + " \"" ;

ObjectQuery query = new ObjectQuery （wmiQuery）;

我正在设置连接和管理范围的用户名，密码，名称为i n上面的查询字符串是我的应用程序的名称。

当我遍历 ManagementObjectCollection 。

Why do the Remote WMI calls to OCS R2 Server fails? (Details below). Am I missing any setup on the OCS server?

 

I’m trying to read the instances of MSFT_SIPTrustedAddInServiceSetting from an remote PC and the request fails with a Win32 error "An operations error occurred.". I tried to read most of the OCS R2 provider classes and getting the same error while I’m able to read class provided by the system (MSFT_Providers works fine). When tried this operation on the ‘OCS R2 system’ (Local WMI) it works well.

 

Setup:

·         ‘OCS R2 system’ and ‘WMI Client PC’ are in the same domain and the ‘WMI client PC’ login with a domain user who is a local administrator on ‘OCS R2 system’

·         I used the tools ‘wbemtest’ and ‘WMI CIM Studio’ to try the above operation

·         Also wrote a WMI client application and it fails in step 5 below

1.       CoInitializeSecurity

2.       CoCreateInstance( IWbemLocator )

3.       IWbemLocator->ConnectServer( OCS Server, admin user on OCS, password, ……, IWbeServices)

4.       IWbemServices->ExecuteQuery(WQL, "Select * from MSFT_SIPTrustedAddInServiceSetting",…., IEnumWbemClassObject)

5.       IEnumWbemClassObject->Next(……, IWbemClassObject)

6.       IWbemClassObject->Get(PropertyName,PropertyValue)

 

解决方案

Hi,

I'm having the exact same issue, everything works fine on the host with OCS R2 installed, but accessing the WMI from a remote PC give the following exception.

(Exception from HRESULT: 0x80072020)

   at System.Runtime.InteropServices.Marshal.ThrowExceptionForHRInternal(Int32 errorCode, IntPtr errorInfo)
   at System.Management.ManagementObjectCollection.ManagementObjectEnumerator.MoveNext()
   at System.Management.ManagementObjectCollection.get_Count()

 

string wmiQuery = "SELECT * FROM MSFT_SIPTrustedAddInServiceSetting WHERE TYPE = \"" + name + "\"";

 

ObjectQuery query = new ObjectQuery(wmiQuery);

I'm setting the username, password for the connection and management scope, name in the above query string is the name of my application.

The exception is raised when i iterate over the  ManagementObjectCollection returned from the above query.
