i have 2 machines networked into a linksys hub which is in turn linked to a DSL modem.
both machines have an equally fast internet connection, which implies to me that there is no physical network problem. machine A sees the drives easily on machine B and can view them quickly. B however, takes forever to open the drives on A but can eventually open documents. B can print to A's printer at a reasonable speed.
both have tcp/ip, ipx/spx, netbui, MS networking installed. drives on both are mapped and sharing parameters all seem correct.
i have installed and reinstalled protocols and tried everything else i can think of.
