I've not run across this issue before.  Can you tell me more about the
environment?  The version of Windows Server, the hardware of the
server(s), etc. ?

Also, what log file are you trying to retrieve?  And what does your
WQL query look like? (i.e. "Select * from Win32_NTLogEvent Where
Logfile = 'Security'")

And finally, if you're doing this currently with VBScript, have you
thought about changing languages?  I know that in general timeouts for
objWMI/GetObject in VBScript are an issue.  Seems to me that if you
were to write your handler in, say C#, that you would be able to
increase the connection timeout to whatever you wanted.
