Connection failed (Cannot Connect)

  Hi
  
  We have a help page dedicated to troubleshooting our various data collection methods. It's worth trying the 'Testing WMI' section for any servers that are getting this problem. This should highlight whether it's a configuration issue or not.

  Hope this helps

  What Server OS are you getting theese errors on? Windows Server 2008 R2 has a win32_service memory leak with that error. Look in the server logs and see if you see any wmi exceptions.
  
  I can point you to a Microsoft hotfix if it is the same OS.

  after some time I start getting these errors:
  
  3 Dec 2010 11:52 AM WMI GetInstances: root\cimv2 select Name,State,StartMode from Win32_Service Cannot connect COMException
  
  and then monitoring for a server stops.
  
  I also see these errors all the time:
  
  3 Dec 2010 11:52 AM WMI GetInstances: root\cimv2 select Handle,CreationDate,ProcessId from Win32_Process where CreationDate = '20101203195242.588801+000' and ProcessId = 8196 Cannot connect ManagementException Out of memory

  THanks Harold.
  
  I grabbed that hotfix and have it applied. We'll see if the error goes away, but it definitely looks to be a match.
  
  I also ran across this WMI memory leak article. http://support.microsoft.com/kb/977357
