VMWare server host agent service won’t start

I'm using VMWare Server 2.0 on Windows Server 2003 R2. Sometimes after restarting the host machine, the VMWare host agent service won't start due to an error.

This is the error messages from Event Viewer:

[Service control manager] Timeout
(30000 milliseconds) waiting for the
VMware Host Agent service to connect.

[Service control manager] The VMware
Host Agent service failed to start due
to the following error: The service
did not respond to the start or
control request in a timely fashion.

I've set the service to automatically restart after subsequent failure using services.msc (using a 10 min. delay), but it still won't start. Only starting the service manually seems to work.

Has anyone experienced this before? What workarounds or fixes are there?

Here's a small vbs script that i use to check whether a service is running or not, and automatically starts it if it's not running. I use the scheduler to run this script every 15min.

strComputer = "." 
strSvcName = "VMWareHostd" 

set objWMI = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")

set objService = objWMI.Get("Win32_Service.Name='" & strSvcName & "'")

If objService.State= "Stopped" Then
    call SendEmail("servicescheck@pc.local","admin@pc.local","Service X stopped","")
    objService.StartService()
End If


Private function SendEmail(From, Destination, Subject, Textbody)

    sch = "http://schemas.microsoft.com/cdo/configuration/" 

    Set objEmail = CreateObject("CDO.Message")
    Set objCdoConfig = CreateObject("CDO.Configuration")

    With objCdoConfig.Fields 
        .Item(sch & "sendusing") = 2 ' cdoSendUsingPort 
        .Item(sch & "smtpserver") = "127.0.0.1" 
        .update 
    End With 

    with objEmail

        set .Configuration = objCdoConfig

        .From = From
        .To = Destination
        .Subject = Subject
        .Textbody = Textbody

    end with

    call objEmail.Send

end function
