Stopping/Starting a remote Windows service and waiting for it to open/close
I created a set of batch scripts that use sc.exe to do just this. They are attached below. To run these scripts, you should be a user with administration rights on the target machine and running this from a computer that is a member of the same domain. It's possible to set it up to be able to run from outside of the domain (like from a VPN) but there are a lot of layers of security to work through involving firewalls, DCOM and security credentials.
One of these days, I'm going to figure out the PowerShell equivalent, which should be much easier.

What about powershell and WaitForStatus? Eg, the script below would restart SQL Server on a remote machine:
$computer = "COMPUTER_NAME"$me = new-object -typename System.Management.Automation.PSCredential -argumentlist "DOMAIN\user", (convertto-securestring "password" -asplaintext -force)$restartSqlServer = { $sqlServer = get-service mssqlserver $waitInterval = new-timespan -seconds 5 if (-not ($sqlServer.Status -eq "Stopped")) { $sqlServer.Stop() $sqlServer.WaitForStatus('Stopped', $waitInterval) } $sqlServer.Start() $sqlServer.WaitForStatus('Running', $waitInterval) } icm -ComputerName $computer -ScriptBlock $restartSqlServer -Credential $me
I've never actually seen something that does this specifically but it would be quite easy to knock such a utility out in C\C#\VB or any other language that gives easy access to the Service API. Here's a sample of something in C#.
using System;using System.ComponentModel;using System.ServiceProcess;namespace SCSync{ class Program { private const int ERROR_SUCCESS = 0; private const int ERROR_INVALID_COMMAND_LINE = 1; private const int ERROR_NO_ACCESS = 2; private const int ERROR_COMMAND_TIMEOUT = 3; private const int ERROR_NO_SERVICE = 4; private const int ERROR_NO_SERVER = 5; private const int ERROR_INVALID_STATE = 6; private const int ERROR_UNSPECIFIED = 7; static int Main(string[] args) { if (args.Length < 2 || args.Length > 4) { ShowUsage(); return ERROR_INVALID_COMMAND_LINE; } string serviceName = args[0]; string command = args[1].ToUpper(); string serverName = "."; string timeoutString = "30"; int timeout; if (args.Length > 2) { if (args[2].StartsWith(@"\\")) { serverName = args[2].Substring(2); if (args.Length > 3) { timeoutString = args[3]; } } else { timeoutString = args[2]; } } if (!int.TryParse(timeoutString, out timeout)) { Console.WriteLine("Invalid timeout value.\n"); ShowUsage(); return ERROR_INVALID_COMMAND_LINE; } try { ServiceController sc = new ServiceController(serviceName, serverName); switch (command) { case "START": sc.Start(); sc.WaitForStatus(ServiceControllerStatus.Running, new TimeSpan(0, 0, 0, timeout)); break; case "STOP": sc.Stop(); sc.WaitForStatus(ServiceControllerStatus.Stopped, new TimeSpan(0, 0, 0, timeout)); break; case "PAUSE": sc.Pause(); sc.WaitForStatus(ServiceControllerStatus.Paused, new TimeSpan(0, 0, 0, timeout)); break; case "CONTINUE": sc.Continue(); sc.WaitForStatus(ServiceControllerStatus.Running, new TimeSpan(0, 0, 0, timeout)); break; default: Console.WriteLine("Invalid command value.\n"); ShowUsage(); return ERROR_INVALID_COMMAND_LINE; } } catch (System.ServiceProcess.TimeoutException) { Console.WriteLine("Operation timed out.\n"); return ERROR_COMMAND_TIMEOUT; } catch (UnauthorizedAccessException) { Console.WriteLine("You are not authorized to perform this action.\n"); return ERROR_NO_ACCESS; } catch (InvalidOperationException opEx) { Win32Exception winEx = opEx.InnerException as Win32Exception; if (winEx != null) { switch (winEx.NativeErrorCode) { case 5: //ERROR_ACCESS_DENIED Console.WriteLine("You are not authorized to perform this action.\n"); return ERROR_NO_ACCESS; case 1722: //RPC_S_SERVER_UNAVAILABLE Console.WriteLine("The server is unavailable or does not exist.\n"); return ERROR_NO_SERVER; case 1060: //ERROR_SERVICE_DOES_NOT_EXIST Console.WriteLine("The service does not exist.\n"); return ERROR_NO_SERVICE; case 1056: //ERROR_SERVICE_ALREADY_RUNNING Console.WriteLine("The service is already running.\n"); return ERROR_INVALID_STATE; case 1062: //ERROR_SERVICE_NOT_ACTIVE Console.WriteLine("The service is not running.\n"); return ERROR_INVALID_STATE; default: break; } } Console.WriteLine(opEx.ToString()); return ERROR_UNSPECIFIED; } catch (Exception ex) { Console.WriteLine(ex.ToString()); return ERROR_UNSPECIFIED; } return ERROR_SUCCESS; } private static void ShowUsage() { Console.WriteLine("SCSync usage:\n"); Console.WriteLine("SCSync.exe service command <server> <timeout>\n"); Console.WriteLine(" service The name of the service upon which the command will act. (Required)"); Console.WriteLine(" command The command to execute - one of: start|stop|pause|continue. (Required)"); Console.WriteLine(" server The name of the server on which the target service runs. This must start with \\. (Optional)"); Console.WriteLine(" timeout The timeout period in seconds in which the command should finish. The default is 30 seconds. (Optional)"); Console.WriteLine("\n"); } }}The WaitForStatus is just a polling loop and could be easily replaced in any other language. The rest is just OpenService and ControlService.
