Yes.. It was a PDC and I use 2 NIC in RedHat 7.2 with the following IP addresses:

Eth0 -> 192.168.0.1
Eth1 -> 202.152.40.38

Hostname + Domain = MyRedHat.com
DomainName = com
Alias = Winan.com


on NT4 -> it's IP address is 202.152.40.45, and its name is mail, domain = mydomain

The problem is:

in NT4:

1. I can not ping to 192.168.0.1 -==> Request Time out (but, I can ping to 202.152.40.38)

2. I can not ping MyRedHat.com or Winan.com


Hopefully, you can help me to solve this problem and thanks a lot in advance ..

Best regards
Winan
