W2000: IRP_MJ_QUERY_INFORMATION and FileNameInformation

Hi,
I have noticed that under W2000 function IRP_MJ_QUERY_INFORMATION fails
sometimes when requested for FileNameInformation.

It fails with INVALID_PARAMETER when the target for the request is the
LanMan
redirector. I have checked thousand of times all parameters but cannot
discover the
problem.

Anyone knows about some difference in this function under W2000 with regards
to NT4.

Please, note that for local file systems under W2000 it works okay.(Under
NT4 is works in all cases)

Thanks.
Inaki.
