Thanks very much for the reply.
You didn't try the "Release All/Renew All" while you had ICS running. Pity.
It probably would have worke
No, I didn't do this. I was up against time in the end and as it's not
a critical issue I'm returning tomorrow to finish off.
I am confused, now. The first three computers had fixed IP addresses, but
the last was dynamic? I think you have it backwards. As I recall, from
running ICS about 3-1/2 years ago, it assigned IP addresses dynamically,
starting with the first free LAN IP address after the base LAN IP address.
The first computer had the base IP address, the 2nd and 3rd computers got
the next sequential IP addresses, '2', and '3', respectively. The 4th
computer would have gotten '4', had it gotten an IP address dynamically. It
must have been fixed a '84', for some reason.
The first 3 PCs did have fixed IPs. It was the last PC that was set to
dynamically obtain it's IP from the'old' ICS server. Where it got
192.168.0.84 from I don't know. I'm guessing someone had previously
set it as a fixed one and subsequently changing to dynamic kept the
same address. This is just my assumption.
The 4th PC failed to obtain it's IP dynamically as expected.
In Network Properties for the fourth computer, where you put a fixed IP
address on the TCP/IP Properties, you also use set the "Gateway" tab for the
router IP address, you made sure that the WINS Configuration tab was set to
disable WINS Configuration, and and WINS DHCP, ***AND*** you went to the DNS
Configuration tab and manually added the ISPs DNS servers, didn't you?
I did indeed
)
That question doesn't make any sense; but I'll bet it should have been, "Why
didn't the 4th PC obtain its IP address dynamically from the router as all
the others had?" If I am right in my guess that your description was
backward, the first three computers were set to obtain an IP address
automatically, but the fourth one was not. That would explain what you
described.
I'm afraid it doesn't! A logical explanation but doesn't apply in this
case I'm afraid!
One of two things. If there is no need for a static assignment, check the
following tabs for the TCP/IP Properties of that computer:
DNS Configuraton:
Disable DNS
Did that
Gateway:
No entries. Empty.
Did that too!
WINS Configuration (I've seen this set wrong, so check it):
Disable WINS Resolution
Yup, that too
IP Address:
Obtain an IP address automatically.
and that.
I do recall in the dim and distant past having to edit one or more of
the .ini files, but I'm not sure!
I think it was the protocol.ini file or maybe the protocol section
within one of the other .ini files! Had to delete network entries or
something similar
Things from the dim and distant past are often best forgotten.
At my age, these things get forgotten forever.
One other thing that confused me; in the part that I snipped, you said:
"2nd PC:
A SERVER PC running windows 98SE and fixed IP 192.168.0.2"
A server in what sense? There may also be an issue here, if this is not set
up properly.
When I sent the original post, I knew I shouldn't have used the word
Server - it just happened to be the name of the PC.
This is a bog standard peer-to-peer LAN - Sorry about that.
Thanks once more for your time in replying.
Regards

I visited a client today with a network of 4 PCs...

The system was working just fine until my visit today!!!
My brief was to install a new DSLModem/Wireless/Router and add a new
notebook PC to the LAN wirelessly and enable internet connection to
it.
I removed the old hub and USB modem from the 1st PC. I then
reconfigured the Network cards of 1st, 2nd & 3rd PCs to obtain their
IP addresses dynamically from the new router.
And you disabled ICS. I am just checking, here; there is no need for it now.
I installed the new 3Com DSLModem/Wireless/Router using it's default
IP 192.168.1.1. In short, PCs 1, 2 & 3 were returned to full
functionality enjoying the internet connection and shares etc etc.
I then restarted the 4th PC expecting it to have a new IP in the
192.168.1.* range. After restarting I used the IPCONFIG command from a
DOS window which showed the IP address to be the old 192.168.0.84. I
tried to PING the router at 192.168.1.1 and it failed!
You didn't try the "Release All/Renew All" while you had ICS running. Pity.
It probably would have worked.
I restarted the PC again but still it had the IP address 192.168.0.1.
Pinging the router again failed! I then fixed the IP address at
192.168.1.84, restarted the PC and this time I was able to PING the
router however. I could not get an internet connection.

I treid setting the Gateway to 192.168.1.1, restarted the PC but still
no internet connection.

So guys, it's over to you as I'm stuck!!
1. Why wouldn't the PC obtain it's IP dynamically from the router as
all the others hadn't?

2. How the heck can this PC get access to the net through the router
as the other PCs do?
One of two things. If there is no need for a static assignment, check the
following tabs for the TCP/IP Properties of that computer:
DNS Configuraton:
Disable DNS
Gateway:
No entries. Empty.
WINS Configuration (I've seen this set wrong, so check it):
Disable WINS Resolution
IP Address:
Obtain an IP address automatically.
Before you reboot the computer, use IPCONFIG to release the IP address
lease, if it will let you. (I don't know if it will, when you set it
statically, as you did, but it won't hurt to try.)
After it reboots, it should work as the other computers do.
If it needs static IP address assignment, the tabs should be:
DNS Configuration:
ISP DNS Server NO.1
ISP DNS Server NO.2
ISP DNS Server No.3 (if applicable; most ISPs don't have three, but some
do.)
Gateway:
192.168.1.1
WINS Resolution:
Disable WINS Resolution
IP Address:
192.168.1.84
