Restart service if it is not running.

Is there a batch or vbscript file that can check to see if a service is running.  If a service is running then the script will do nothing.  If the service isn't running then it would start the service.

Also, the same for a process.  If the process isn't running then it would start the process.

Thank you.

See: http://technet.microsoft.com/en-us/library/cc773035(v=ws.10).aspx

The command: NET START {service}  will start a service; if it is already running, it will just tell you so!

Hi, you can use this for a service:
Const wbemFlagReturnImmediately = &h10
Const wbemFlagForwardOnly = &h20

strComputer = "."
strServiceName = "spooler"

Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\CIMV2")
Set colItems = objWMIService.ExecQuery("SELECT * FROM Win32_Service Where Name='" & strServiceName & "'", "WQL", wbemFlagReturnImmediately + wbemFlagForwardOnly)
For Each objItem In colItems
	If objItem.State <> "Running" Then objItm.StartService()
Next

Open in new window


and this for a process:
Const wbemFlagReturnImmediately = &h10
Const wbemFlagForwardOnly = &h20

strComputer = "."
strProcessPath = "c:\temp\myprogram.exe"

Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\CIMV2")
Set colItems = objWMIService.ExecQuery("SELECT * FROM Win32_Service Where Name='" & Mid(strProcessPath, InStrRev(strProcessPath, "\") + 1) & "'", "WQL", wbemFlagReturnImmediately + wbemFlagForwardOnly)
blnFound = False
For Each objItem In colItems
	blnFound = True
Next
If blnFound = False Then
	Set objShell = CreateObject("WScript.Shell")
	objShell.Run strProcessPath, 1, False
End If

Open in new window


Regards,

Rob.

If you're running Windows 2008 or 7, you can set an event log task to restart the service.

We use it because it doesn't require us to have an extra service constantly running the vbscript.

Event log tasks can be set by selecting a specific error log entry for your service, clicking "Attach a task to this log..." and setting the task to cmd /c "sc start MyService"

Rob,

I receive an error when running the first vbscript.  I attached the file.  The process file just runs with no action.

Thank you.

Sorry, missed the "e" in objItem.  Here is the correct "service" code.

Rob.

Const wbemFlagReturnImmediately = &h10
Const wbemFlagForwardOnly = &h20

strComputer = "."
strServiceName = "spooler"

Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\CIMV2")
Set colItems = objWMIService.ExecQuery("SELECT * FROM Win32_Service Where Name='" & strServiceName & "'", "WQL", wbemFlagReturnImmediately + wbemFlagForwardOnly)
For Each objItem In colItems
	If objItem.State <> "Running" Then objItem.StartService()
Next

Ooop, just saw a mistake in the process code as well.  I accidentally left in Win32_Service instead of Win32_Process

Regards,

Rob

Const wbemFlagReturnImmediately = &h10
Const wbemFlagForwardOnly = &h20

strComputer = "."
strProcessPath = "c:\temp\myprogram.exe"

Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\CIMV2")
Set colItems = objWMIService.ExecQuery("SELECT * FROM Win32_Process Where Name='" & Mid(strProcessPath, InStrRev(strProcessPath, "\") + 1) & "'", "WQL", wbemFlagReturnImmediately + wbemFlagForwardOnly)
blnFound = False
For Each objItem In colItems
	blnFound = True
Next
If blnFound = False Then
	Set objShell = CreateObject("WScript.Shell")
	objShell.Run strProcessPath, 1, False
End If
