When I try to start the MongoDB service, I get the following:

• <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event">
• <System>
  <Provider Name="Service Control Manager" Guid=" {555908d1-a6d7-4695-8e1e-26931d2012f4}

  " EventSourceName="Service Control Manager" />
  <EventID Qualifiers="49152">7031</EventID>

  <Correlation />
  <Execution ProcessID="684" ThreadID="3040" />
  <Channel>System</Channel>

  <Security />
  </System>

• <EventData>
  <Data Name="param1">Mongo DB</Data>
  <Data Name="param2">1</Data>
  <Data Name="param3">0</Data>
  <Data Name="param4">1</Data>
  <Data Name="param5">Restart the service</Data>
  </EventData>
  </Event>

I created the service using: C:\mongodb\bin\mongod.exe --install --dbpath=..\db --logpath=..\mongo.log --logappend -vvvvv

When I run directly from the cmd console, it works fine.
