Question

我必须更改数百个MSSQL服务器和代理的服务帐户。

Microsoft建议使用sql服务器配置管理器。这种方法可以正常工作，但是如果必须执行一百次，那将是可怕的。

在Powershell运行良好的最新服务器（Windows Server 2016，SQL Server 2016/2017）上：

$computer = $env:computername
[void][reflection.assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo")
[void][reflection.assembly]::LoadWithPartialName("Microsoft.SqlServer.SqlWmiManagement")
$wmi = New-Object ("Microsoft.SqlServer.Management.Smo.Wmi.ManagedComputer") $computer
$wmi.Services | Select Name, DisplayName, Type, StartMode, ServiceState, 
ServiceAccount | ft -auto
$sqlserver = $wmi.Services | where {$_.Type -eq "SqlServer"}
$sqlserver.SetServiceAccount($account, $pw)

但是，几乎每台较旧的服务器（Windows Server 2008-2012R2，SQL Server 2008-2014）都会为我提供一个空的WmiConnectionInfo，这是一个例外：

ConnectionSettings : Microsoft.SqlServer.Management.Smo.Wmi.WmiConnectionInfo
Services           : 
ClientProtocols    : 
ServerInstances    : 
ServerAliases      : 
Urn                : ManagedComputer[@Name='SERVER']
Name               : SERVER
Properties         : {}
UserData           : 
State              : Existing
The following exception occurred while trying to enumerate the collection: "SQL Server WMI provider is not available on SERVER.".

在旧服务器上，我检查了已加载的组件。 [reflection.assembly] ::: LoadWithPartialName（“ Microsoft.SqlServer.Smo”）。FullName提供[...] 版本= 13.0.0.0 [...]。 SQL Server 2014是版本12，而不是13。

但是，即使我加载了正确（？）版本的dll，结果也保持不变。

[reflection.assembly]::Load("Microsoft.SqlServer.Smo, Version=12.0.0.0, Culture=neutral, PublicKeyToken=...")
[reflection.assembly]::Load("Microsoft.SqlServer.SqlWmiManagement, Version=12.0.0.0, Culture=neutral, PublicKeyToken=...")

我是否需要使用正确的版本加载更多的分析物？是否有另一种建议的方法通过Powershell更改mssql服务帐户？

有趣。程序集和Server 2012似乎有些不兼容。如果我针对SQL Server 2012实例运行它：

Add-Type -AssemblyName "Microsoft.SqlServer.Smo, Version=12.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"
Add-Type -AssemblyName "Microsoft.SqlServer.SqlWmiManagement, Version=12.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"
$wmi = New-Object -TypeName "Microsoft.SqlServer.Management.Smo.Wmi.ManagedComputer" -ArgumentList $ServerName
$wmi.Services | Select-Object -Property Name, DisplayName, Type, StartMode, ServiceState, ServiceAccount | Format-Table -AutoSize

我得到：

Name           DisplayName                                                 Type StartMode ServiceState
----           -----------                                                 ---- --------- ------------
MsDtsServer100 SQL Server Integration Services 10.0 SqlServerIntegrationService  Disabled      Stopped

（注意：出于隐私目的，我在这里故意切断了ServiceAccount列。）

但是对于SQL Server 2008 R2实例，我得到：

Name                   DisplayName                                                               Type StartMode ServiceState
----                   -----------                                                               ---- --------- ------------

但是，如果我使用v14的程序集：

Add-Type -AssemblyName "Microsoft.SqlServer.Smo, Version=14.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"
Add-Type -AssemblyName "Microsoft.SqlServer.SqlWmiManagement, Version=14.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"
$wmi = New-Object -TypeName "Microsoft.SqlServer.Management.Smo.Wmi.ManagedComputer" -ArgumentList $ServerName
$wmi.Services | Select-Object -Property Name, DisplayName, Type, StartMode, ServiceState, ServiceAccount | Format-Table -AutoSize

SQL Server 2012：

Name                   DisplayName                                                               Type StartMode ServiceState
----                   -----------                                                               ---- --------- ------------

SQL Server 2008 R2：

Name                   DisplayName                                                               Type StartMode ServiceState

不幸的是，我没有可以安全地对其进行测试的SQL Server 2014或更高版本。

我不确定是否要从PowerShell库中从Microsoft的SqlServer PowerShell模块中获取程序集的版本14，还是从SSMS v17中获得它。

实际上我的系统上仍有v10的程序集可用，它们的工作方式与v12程序集一样。

我想知道这是错误还是已知问题。

Answer 2

这种方法解决了我的问题。

我使用以下命令检查已加载的程序集：

$dlls = [System.AppDomain]::CurrentDomain.GetAssemblies()
$dlls | where {$_.Location -match "SQL"}

我相信，我已经找到了大多数情况下的解决方案（Windows Server 2008-2012R2，SQL Server 2008-2014）。

Add-Type -path "C:\Program Files (x86)\Microsoft SQL Server\$version\SDK\Assemblies\Microsoft.SqlServer.Smo.dll"
Add-Type -path "C:\Program Files (x86)\Microsoft SQL Server\$version\SDK\Assemblies\Microsoft.SqlServer.SqlWmiManagement.dll"

有时路径是不同的。有时正确的dll位于目录中，该目录在安装时指定为INSTALLSHAREDWOWDIR。也许是就地升级或安装新的管理工作室的结果。

更多最新的服务器（Windows Server 2016，SQL Server 2016/2017）可与[void] [reflection.assembly] :: LoadWithPartialName（“ Microsoft.SqlServer.Smo”），...配合使用。

使用Powershell更改mssql服务帐户，但不更改带有LoadWithPartialName的SQL Server WMI提供程序
