我正在尝试使用备用凭据管理(启动/停止)远程计算机上的Windows服务。我知道我可以使用ServiceController类来使用我当前的凭据来管理服务:
Dim sc As New ServiceController(ServiceName, ComputerName)
但我想使用不同的凭据。我正在使用的其他类(DirectoryEntry和System.Management)都支持使用备用凭据...非常感谢帮助。

我必须承认我怀疑它会起作用......但下面是代码。我不得不对你建议的代码做一个小改动。每当我尝试IPC $时,它会返回53结果代码,即使我确定该共享存在。所以在另一个网站的建议下,我删除了共享,只删除了计算机名称,这很有效。

Sub Main()
Dim Computername As String = "SomeComputer"
'Create connection to remote computer'
Using nc As New NetworkConnection("\\" + Computername, New NetworkCredential("Domain\User", "Password"))
Dim sc As New ServiceController("Windows Firewall/Internet Connection Sharing (ICS)", Computername)
'now we can start/stop/whatever we want here'
End Using
Console.ReadLine()
End Sub

Dim result = WNetAddConnection2(netResource, credentials.Password, credentials.UserName, 0)

要进行远程登录,您应使用WNetAddConnection2
(请参阅http://msdn.microsoft.com/en-us/library/aa385413.aspx)或NetUseAdd
(请参阅http://msdn.microsoft.com/en-us/library/aa370645.aspx)API。您可以使用\\RemoteComputer\IPC$
作为目标资源。
更新基于评论中的问题:关于IPC $会话的解释可能很长。只是主要信息。
如果您想在远程计算机上执行某些操作,首先要做的是与远程计算机建立经过身份验证的“连接”。远程计算机上的网络登录(远程登录)将完成,这与其他本地登录相同。网络登录会话保持不变,如果您与例如\\RemoteComputer\share1
和计算机上的另一个程序有连接,请尝试访问\\RemoteComputer\share2
,将使用相同的会话。
您可以使用net.exe
模拟情况。只需启动cmd.exe
并输入
net use \\RemoteComputer\IPC$ /u:Domain\User password
或
net use \\RemoteComputer\IPC$ /u:RemoteComputer\LocalRemoteUser password
然后您将与目标计算机建立连接。然后,您可以在资源管理器中键入\\RemoteComputer\AnyShare
,并在用户的Domain\User
或RemoteComputer\LocalRemoteUser
凭据下访问文件系统。断开连接
net use \\RemoteComputer\IPC /d
如果您尝试在远程计算机上启动/停止服务,则将尝试建立相同的IPC会话。如果您已经使用其中一个用户凭据进行此类会话,则将使用该会话。函数WNetAddConnection2
,NetUseAdd
可用作“净使用”的替代。如果您永久要使用其他用户的凭据访问远程计算机,则可以使用CredWrite
,CredWriteDomainCredentials
或CredUIPromptForCredentials
/ CredUIPromptForWindowsCredentials
。 Cred-function对我来说似乎不是最好的方式。
