假设一些Windows服务使用的代码需要映射网络驱动器,而不需要UNC路径。当服务启动时,如何使驱动器映射可用于服务的会话?作为服务用户登录并创建持久映射将不会在实际服务的上下文中建立映射。

更好的方法是使用mklink.exe使用符号链接。你可以在文件系统中创建一个任何应用程序都可以使用的链接。见http://en.wikipedia.org/wiki/NTFS_symbolic_link。

我发现了一个解决方案,它与使用psexec的解决方案类似,但不需要额外的工具就可以工作,并且可以在重新启动后继续工作。

只需添加一个计划任务,在“作为运行”字段中插入“system”,并使用简单的命令将任务指向一个批处理文件

net use z: \servername\sharedfolder /persistent:yes

然后选择“在系统启动时运行”(或类似的,我没有英文版本),你就完成了。

您要么需要修改服务,要么将其包装到辅助进程中:除了会话/驱动器访问问题外,持久驱动器映射仅在交互式登录时恢复,而服务通常不会执行。

helper进程方法可以非常简单:只需创建一个映射驱动器的新服务并启动“真正的”服务。唯一不是完全无关紧要的事情是:

The helper service will need to pass on all appropriate SCM commands (start/stop, etc.) to the real service. If the real service accepts custom SCM commands, remember to pass those on as well (I don't expect a service that considers UNC paths exotic to use such commands, though...) Things may get a bit tricky credential-wise. If the real service runs under a normal user account, you can run the helper service under that account as well, and all should be OK as long as the account has appropriate access to the network share. If the real service will only work when run as LOCALSYSTEM or somesuch, things get more interesting, as it either won't be able to 'see' the network drive at all, or require some credential juggling to get things to work.

我发现了一个非常简单的方法:使用powershell的“New-SmbGlobalMapping”命令,它将全局挂载驱动器:

$User = "usernmae"
$PWord = ConvertTo-SecureString -String "password" -AsPlainText -Force
$creds = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $User, $PWord
New-SmbGlobalMapping -RemotePath \\192.168.88.11\shares -Credential $creds -LocalPath S:

你可以使用'net use'命令:

var p = System.Diagnostics.Process.Start("net.exe", "use K: \\\\Server\\path");
var isCompleted = p.WaitForExit(5000);

如果这在服务中不起作用,请尝试Winapi和PInvoke WNetAddConnection2

编辑:显然我误解你了——你不能改变服务的源代码,对吗?在这种情况下,我会遵循mdb的建议,但稍微改变一下:创建自己的服务(让我们称之为映射服务)来映射驱动器,并将这个映射服务添加到第一个(实际工作的)服务的依赖项中。这样,在映射服务启动(并映射驱动器)之前,工作服务将不会启动。

ForcePush,

注意:新创建的映射驱动器现在会出现在这个系统的所有用户面前,但他们会看到它显示为“断开连接的网络驱动器(Z:)”。别被名字骗了。它可能声称是断开连接的,但它对每个人都适用。这就是为什么你可以告诉这个黑客是不支持M$…

It all depends on the share permissions. If you have Everyone in the share permissions, this mapped drive will be accessible by other users. But if you have only some particular user whose credentials you used in your batch script and this batch script was added to the Startup scripts, only System account will have access to that share not even Administrator. So if you use, for example, a scheduled ntbackuo job, System account must be used in 'Run as'. If your service's 'Log on as: Local System account' it should work.

What I did, I didn't map any drive letter in my startup script, just used net use \\\server\share ... and used UNC path in my scheduled jobs. Added a logon script (or just add a batch file to the startup folder) with the mapping to the same share with some drive letter: net use Z: \\\... with the same credentials. Now the logged user can see and access that mapped drive. There are 2 connections to the same share. In this case the user doesn't see that annoying "Disconnected network drive ...". But if you really need access to that share by the drive letter not just UNC, map that share with the different drive letters, e.g. Y for System and Z for users.
