Connections to LAN work only partially

Hello,

i have a problem i can't fix:

I tried to integrate a Win98 SE notebook to a LAN for access to internet
but the notebook gets only connection to LAN machines through the
Network Neighbourhood.
Ping, telnet or HTTP request to machines of LAN don't work.


The setting:
=============
Every computer in the LAN has its very own name and IP address and
belongs to one workgroup.
There is no DHCP but a DNS.
The DNS is simutaneous the gateway and router to WAN.
The router 'knows' the Win98 SE notebook and can ping it.

The Win98 notebook can't ping a remote computer in the LAN: "Connection
timed out".
But remote computers can ping the Win98 SE notebook.

In the Network Neighbourhood of other machines the Win98 SE notebook is
visible near other machines.
In the Network Neighbourhood of the Win98 SE notebook the other machines
are visible, too.



Win98 SE notebook:
==================
IP: 192.168.0.30
Sub: 255.255.255.0
Default gateway: 192.168.0.1
DNS is activated.
DNS: 192.168.0.1
Workgroup: LocalWorkgroupName
Search for domain suffix: LocalWorkgroupName
"NetBIOS over TCP/IP" is activated.

File "hosts" contains assigned IPs and corresponding names of all
machines in the LAN.
The NIC is a PC-Card (Level One 10-100Mbps 32 bit iPort PC Card).
Additionally there is a driver for USB Network Adapter installed (with
bindings for TCP/IP and Net-BEUI).
The network settings for this device contain an IP address
(192.168.0.177) and a gateway for another, different LAN.

It has no service packs installed.


Results of pings:
=================
ping 127.0.0.1 works.
ping localhost works.
ping 192.168.0.30 works.
ping 'Win98MachineName' works.
ping 'remoteMachineName' does not work.
ping 192.168.0.1 does not work.
ping 'gatewayName' does not work.

ping 192.168.0.177 works (the IP of the temporarely used USB Network
Adapter)


My trials to solve the problem:
===============================
- Re-install driver for NIC.
- Re-install TCP/IP and NetBEUI


My questions:
=============
- How can i prepare this notebook to go to internet through our router?
- Is it possible that the settings for the USB Network Adapter avoid the
connection to internet through our router?


Thanks in advance,
Joerg

If I understand correctly, this computer has two different network
adapters (PC Card and USB) with IP addresses in the same subnet.
That's very likely to cause problems, because it will use one or the
other, but not both, to access other hosts.

If the USB adapter has a DHCP address, release it. If it has a static
IP address, change it to a different subnet. Then, try network access
through the PC Card again.

Yes.

The USB adapter has a static IP address.
I changed it to another subnet and the connection to LAN through the PC
Card works fine.
That's it!

I hoped that it would be possible to use different IP addresses for
different devices with the same subnet but i failed.
The change you suggested is so small that it is ok to repeat it for
every change from one LAN to another.

Thank you very much!

Joerg

You're welcome, Joerg. I'm glad that my suggestion helped you solve
