3Com NIC
Diagnostics Program
The 3Com NIC diagnostics program (3Com NIC Doctor) is a Windows-based
program used to troubleshoot and configure NICs installed in PCs running
Windows 98, Windows 95, or Windows NT 4.0.
When the Network Connectivity test evaluates the network connection, it is
possible to receive the message, “No packets were received.” This could be
interpreted by the user as a failure when in some cases the connection can be
functioning properly.
