Hi, Quick definition for Overrun Errors : "The Input Rate has exceeded the buffers ability to handle the data. The buffer in question is the receive buffer" Extract from CIT course notes. Q : Is this buffer referring to the buffer on the network interface card or the system buffer ? I´m presuming the Network Interface Card here. Regards, Phil. ____________________________________________________________ Do You Yahoo!?
