A connection was established but is not a reliable connectio

"A connection was established but is not a reliable connection and was terminated."

PowerPC 7100/66
Mac OS 7.5.5
NCSA Telnet/FreePPP
Connected to a 10/100 Windows ethernet network via a MacSense Nubus RJ45 ethernet card.

I can see the Windows 2003 R2 Server.

Please -- what's my problem?
Is it the Cat5 cable?
I think it's "straight through".
Do I need "crossover" cable?\\Tjank you!

The ethernet cable needs to be straight through.

How is the physical connection to the Windows network achieved? Switch or Hub

Theoretically, it should work.

Any reason for the old machine?

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
