WMI events is don't work

hi!

i try monitor service state through wmi intrinsic events. purpose have made the next vbs scripts:

  'wmi event filter creation script   option explicit  on error resume next    dim strcomputer            dim strnamespace           dim objservice             dim objeventfilterclass    dim objeventfilter           strcomputer = "."  strnamespace = "root\cimv2"    set objservice = getobject("winmgmts:\\" &  strcomputer & "\" & strnamespace)    set objeventfilterclass = objservice.get("__eventfilter")  set objeventfilter = objeventfilterclass.spawninstance_()    objeventfilter.name = "monitoringservices"  objeventfilter.querylanguage = "wql"  objeventfilter.query = "select * __instancemodificationevent within 1 targetinstance isa 'win32_service'"  

  objeventfilter.put_()  

  'event consumer creation script  option explicit  on error resume next    dim strcomputer           dim strnamespace   dim objservice             dim objconsumerclass   dim objconsumer             strcomputer = "."  strnamespace = "root\subscription"    set objservice = getobject("winmgmts:\\" & strcomputer & "\" & strnamespace)  set objconsumerclass = objservice.get("logfileeventconsumer")    set objconsumer = objconsumerclass.spawninstance_()    objconsumer.name = "servicelog"  objconsumer.filename = "c:\temp\logservice.txt"  objconsumer.text = "service %targetinstance.displayname% %targetinstance.state%"  objconsumer.put_()  

  'binding filter consumer  option explicit  on error resume next    dim strcomputer           dim strnamespace        dim objservice             dim objeventfilter         dim objconsumer            dim objbindingclass    dim objbindinginstance       strcomputer = "."  strnamespace = "root\cimv2"    set objservice = getobject("winmgmts:\\" & strcomputer & "\" & strnamespace)  set objeventfilter = objservice.get("__eventfilter.name='monitoringservices'")    strnamespace = "root\subscription"  set objservice = getobject("winmgmts:\\" & strcomputer & "\" & strnamespace)    set objconsumer = objservice.get("logfileeventconsumer.name=""servicelog""")    set objbindingclass = objservice.get("__filtertoconsumerbinding")  set objbindinginstance = objbindingclass.spawninstance_()    objbindinginstance.filter =  objeventfilter.path_  objbindinginstance.consumer = objconsumer.path_  objbindinginstance.put_()  

when run scripts - everything is all right , don't see errors. objects present.

  ps c:\windows\system32> get-wmiobject -class __eventfilter      __genus          : 2  __class          : __eventfilter  __superclass     : __indicationrelated  __dynasty        : __systemclass  __relpath        : __eventfilter.name="monitoringservices"  __property_count : 6  __derivation     : {__indicationrelated, __systemclass}  __server         : n937  __namespace      : root\cimv2  __path           : \\n937\root\cimv2:__eventfilter.name="monitoringservices"  creatorsid       : {1, 5, 0, 0...}  eventaccess      :  eventnamespace   :  name             : monitoringservices  query            : select * __instancemodificationevent within 1 targetinstance isa 'win32_service'  querylanguage    : wql

when try restart service on computer (computername: n937) - c:\temp\logservice.txt doesn't appear.

how make service monitoring through wmi events correctly ?
