"frames lost when buffer exceeded" count skyrockets. Can I increase the size of my buffer?

Using Network Monitor in Windows 2000 Server, I see that almost as many frames are lost due to buffer being exceeded as are being delivered. Is there anything that can be done about this? I have 3 switches (2 siemens speedstream and a D-link DSL router/switch) between the 2 ends of my network. It seems the packets are getting through well, but they are being lost anyway. There is nothing in the Windows NT Server Resource Kit Networking Guide about buffer size; is it even adjustable?

Thanks!!!

This might be an MTU size issue.  I'm not truly an expert on this, but perhaps this will get you started:

it helped some. but i have heard of 8mb/sec on SMB networks>  just trying to get some mo' thruput.  I think that the "buffer" i was referring to is actually a part of the network monitor setup, which of course takes a snapshot of all network activity. So, I was using the wrong tool for my speed estimation. However, I still have not been able to get over 5.5MB/sec on this network (with only one switch between the two machines. I guess that will have to do.

thanks,

Jim
