[英]Restart windows from asp.net page using command prompt and System.Diagnostics.Process
I'm trying to restart windows server 2003 from inside a web service using System.Diagnostics.Process. 我正在尝试使用System.Diagnostics.Process从Web服务内部重新启动Windows Server 2003。
public static string Dorestart()
{
var si = new Process();
si.StartInfo.UserName = "administrator"; // Credentials of administrator user
var sc = new SecureString();
foreach (char c in "AdminPassword")
{
sc.AppendChar(c);
}
si.StartInfo.Password = sc;
si.StartInfo.UseShellExecute = false;
si.StartInfo.FileName = "cmd.exe";
si.StartInfo.Arguments = "\"c:\\windows\\system32\\shutdown.exe\" -r -f -t 0 -c \"Restart Reason\" -d p:4:1";
si.StartInfo.CreateNoWindow = true;
string res = "";
try
{
si.Start();
si.WaitForExit();
res = "Minor Job done... wait 2 minutes to complete action";
}
catch (Exception ex)
{
res= ex.Message;
}
si.Close();
si.Dispose();
return res;
}
for file name and argument part I also tested this: 对于文件名和参数部分,我也对此进行了测试:
si.StartInfo.FileName = "shutdown.exe";
si.StartInfo.Arguments = "/r /f /t 0 /c \"" + UReason + "\" /d p:4:1";
using filename and argument right from RUN command actually restarts the pc but on web service I get this error: 从RUN命令直接使用文件名和参数实际上会重新启动PC,但是在Web服务上却出现此错误:
On server desktop: The application fails to initialize properly (0xC0000142). 在服务器桌面上:应用程序无法正确初始化(0xC0000142)。 Click on ok to terminate application.
单击确定终止应用程序。
In event log I have this: 在事件日志中,我有这个:
Process information:
Process ID: 2676
Process name: w3wp.exe
Account name: NT AUTHORITY\NETWORK SERVICE
Exception information:
Exception type: HttpException
Exception message: Request timed out.
Request information:
Request URL: http://mywebsite.com/webservice.asmx
Request path: /webservice.asmx
User host address: <IP Address>
User:
Is authenticated: False
Authentication Type:
Thread account name: NT AUTHORITY\NETWORK SERVICE
Thread information:
Thread ID: 7
Thread account name: NT AUTHORITY\NETWORK SERVICE
Is impersonating: False
On Web Application there is no error. 在Web应用程序上没有错误。
I appreciate if somebody tell me how can I fix this problem and give restart ability to a web service. 如果有人告诉我如何解决此问题并使Web服务具有重启功能,我将不胜感激。
at last it worked... 终于成功了...
There were a mixture of problems. 有很多问题。 I document the process here for future reference.
我在此处记录了该过程以供将来参考。 Beware of security risks.
当心安全隐患。
Thanks to Wjdavis5 , I changed AppPool Identity to Local System. 多亏了Wjdavis5 ,我将AppPool Identity更改为Local System。
Thanks to Running a batch file from an ASP .NET page , I removed some lines from code: 感谢从ASP .NET页面运行批处理文件 ,我从代码中删除了几行:
public string DoJob()
{
var si = new Process
{
StartInfo =
{
FileName = "shutdown.exe",
Arguments = "-r -f -t 0 -c "Shutdown Reason" -d p:4:1",
WorkingDirectory = "c:\\windows\\system32\\"
}
};
string res;
try
{
si.Start();
si.WaitForExit();
res = "<br />Minor Job done... wait 2 minutes to complete action<br />You can now close this window";
}
catch (Exception ex)
{
res = ex.Message;
}
si.Close();
si.Dispose();
return res;
}
To eliminate security risks, alongside with some security approaches in hiding website and web service, such as using subdomain and non-standard port, I made use of impersonation in A small C# Class for impersonating a User by Uwe Keim the above method content wrapped in this code: 为了消除安全风险,以及隐藏网站和Web服务的一些安全方法(例如,使用子域和非标准端口),我利用Uwe Keim的A小C#类中的模拟用户来伪造上述方法内容,此代码:
try
{
using (new Impersonator("Admin Username", ".", "Admin Password"))
{
// Above method Content
.
.
.
}
}
catch (Exception ex)
{
return "Invalid Username or Password";
}
this code checks if provided credential is valid on server. 此代码检查提供的凭据在服务器上是否有效。 I did not test non-administrative users on this application because this server does not have any.
我没有在此应用程序上测试非管理用户,因为该服务器没有任何用户。
