Please post the following information for three of your PCs:
1. For a PC that can reach the Internet
2. For two PCs that can't.

- Operating system
- IP address
- Default Gateway
- DNS Server
- Result of pinging 209.85.135.104

Hi,

Thanks for responding.

Well we were very busy the last 2 days (doing a live auction), and I wasn't
able to do any testing. Two of my computers have gone home now. I have 9
left on the network and all of them can access the Internet.

I will have to find another couple machines in order to do another test, and
get back to you.

Bob.

The DHCP server and the gateway (the router) in the ipconfig, are the same IP adress: 192.168.1.1. What type of device, name brand, version, etc, is this router?

Is your router a Windows machine? If so, what operating system is it? If it's a Windows desktop operating system (Windows XP, Vista, 7, 2000, etc) being used with ICS, then that explains the 10 concurrent connections limit.

Details will help us diagnose the problem. Looking forward to your reply.

Bob!

I don't believe you ever told us what the Firewall is that you have.

1. You only have a Workgroup
2. You have more than 10 machines
3. Your server is nothing but a file server. The LAN does not depend on it
for anything other than those Files on it. You could throw the server out
in the street and the LAN would run fine other than the lost files.

The Firewall:

Some lower end "pro-sumer" grade firewalls (typically $300 to $600 range)
have a limit on the number of users they will allow. Some use 10 as the
limit, some use 15 as the limit. Yours is probably limited to 10 and once
the limit is hit you are stuck till one of the sessions times out and allows
a new user (hence the randomness).

What kind of router? I'd give pretty long odds that the issue is your
either it or your cable modem limiting you to 10 connections.
