Netstat results, something isnt right??

[UltraJounin]

We just purchased one of these devices at my company http://www.axiomtek.com/products/ViewProduct.asp?view=459
and I was running some diagnostic tests due to poor data transfer...

I ran a netstat -s

Seeing the bolded stats below tells me there is a problem somewhere but I dont know where to look next , any thoughts? I'm having a problem determining whether or not this is NIC or Network related...

No errors anywhere else. Running Standard Server 2003 R2 with WSS
