The problem goes away after we turned on the autonegotiation.
---------------------------------------------------------------------
> Our 2100, running DU 4.0D, has two NICs. One is 10Mb/s, another is
>10/100 Mb/s. Only the 10Mb/s was connected to our LAN. About 2 weeks ago
>we decided to use the 100MB/s NIC. So we deconfigured the 10Mb card and
>configured the new 100MB card. Everything worked fine. This Monday we
>changed the IP address which was a Class C address to a private Class A
>address. Put the old address as an alias. Everything looked fine. We
>didnot have problems to ping outside machines. About 10 Min after we
>finished the reconfig, we canot telnet /rlogin to the machine. All users
>became invalid. login in on the console hangs. Failed to reboot, we
>booted to single user mood. Deconfigured the 100Mb NIC, the machine
>rebooted.
>Then reconfigured the 100MB card with the old IP address, no problem to
>ping the IP address, but canot ping outside machines. Donot know what to
>do, we deconfigure the 100MB card and go back to the old 10MB card.
>Everything works. Looks like the problem is related to the 100Mb card.
>We are planing to do two more tests:
> 1. switch the two cards
> 2. replace the 100Mb card with a new one.

>Any suggestions, clues are highly appreciated!
