Windows Server - Access to the Internet with more than 10 users

Asked By Bob Campbell

13-Mar-10 04:43 PM

I am using a workgroup, not a domain.
I have 12 computers and 2 network printers:

Windows Server 2003 R2 SP2
Windows 7 Ultimate
Windows 7 Professional
Windows 7 Professional
Windows 7 Home Premium
Windows 7 Home Premium  --- No Internet access
Windows Vista Home Premium --- No Internet access
XP SP3 Professional
XP SP3 Media Center --- No Internet access
XP SP3 Media Center
Mac OS X 10.6.2 --- No Internet access
Mac OS X 10.6.2

All computers can access a shared folder on the server.

There seems to be some limit preventing Internet access.

I cannot get 4 computers to access the Internet: marked with "No Internet
access".
It changes from day to day, different machines cannot get on the Internet, in
no discernable way--that I can determine, although the 1 Ultimate and 3
Professional computers can always get on.

Any suggestions?

Hello Bob,

How is your network built:
computer > switch > router > internet

computer > switch > server > router > internet

Also post an unedited ipconfig /all from a problem machine, the ip address
of the router and how the clients get there ip address DCHP from the server
or router.

Best regards

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

- Operating system
- IP address
- Default Gateway
- DNS Server
- Result of pinging 209.85.135.104
- Result of pinging www.google.com

You need to check immediately after obtaining the above details that the PC
still cannot reach the Internet.

Hi,

Thanks for responding.

Well we were very busy the last 2 days (doing a live auction), and I was not
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?=20

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

Bob!

I do not 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.

on it=20
out=20
range)=20
the=20
once=20
allows=20
Microsoft,


I am not sure, but I think the router may well be a Windows workstation =
using ICS, hence why that magic 10 concurrent connection limit number is =
occuring.

Yep!  Could be.
