Help with XP networking

From: David Gondek on 29 Apr 2008 14:36 I am trying to get a small peer-to- peer network set up for file sharing. I can get everything working with the ipx/spx protocol but not with tcp/ip. There are 4 Windows XP Pro computers connected through a Lynksys router and a DSL modem that connect to the Internet fine. Someone previously installed Windows Internet Connection Sharing (ICS) and this may be what is preventing the computers from connecting to folders on other computers and even seeing themselves in 'My Network Places'. I ran the XP Networking Wizard but it keeps saying that I am connecting through ICS no matter what I select. I have tried stopping/disabling the Firewall/ICS service but this doesn't change anything. The DSL modem apparently requires a username and password but when I try setting up a new manual connection this way I can't even connect to the Internet. How do I uninstall ICS? Could the problem be the Internet Gateway software? Do I need ICS for some reason even though there is a router? I have never worked with ICS or networking DSL before so I feel a little lost. Thanks for any help or insight anyone can provide!

You don't need ICS with a router. You can't install or un-install ICS. You can only enable or disable it. Do you see an "Internet Gateway" connection in the Network Connections folder? That's your router. It doesn't indicate that ICS is enabled. If ICS is enabled, you'll see "Shared" in the information about one of the high-speed network connections. Does the Network Setup Wizard say that it has found a shared network connection? That's your router. It doesn't indicate that ICS is enabled. The most likely problem with networking via TCP/IP is that a firewall program is blocking access. Configure any firewall (Windows Firewall, Norton, McAfee, ZoneAlarm, etc) to allow access by other computers on the LAN. Note that some recent antivirus programs have firewall components, such as "Internet Worm Protection" in Norton, that need to be configured. -- Best Wishes, Steve Winograd, MS-MVP (Windows Networking) Please post any reply as a follow-up message in the news group for everyone to see.

From: David Gondek on 29 Apr 2008 16:03 Thanks for the response. I tried disabling the McAfee Firewall but that didn't help. I have two network connections listed on one of the computers. One looks like a normal network connection (with normal properties) and one is listed as 'Internet Connection' which has virtually no information when you check it's properties. Usually I can't disable this 'Internet Connection'. When I try nothing happens. One time I got it disabled for a couple minutes but when I checked again it was enabled. On another computer there is an item labeled 'Internet Gateway' in the components of it's network connection. Using tcp/ip I can access the computer with two network connections listed from other computers but none of the other computers can access anything but themselves. Using ipconfig shows me the ip addresses for the computers are 192.168.0.n --- my understanding is that these are ICS ip addresses not Lynksys router addresses. I would like to use just the router but I can't figure out how. Thanks.

From: Jack (MVP-Networking). on 29 Apr 2008 17:16 Hi I am not familiar with McAfee Firewall but some of these "Genius Firewalls" run processes even when they are disabled. Check the Running processes and the startup and make sure that it is Not Running anything in background. These two free utilities (StartUp & Process Explorer) might help in finding out, http://www.ezlan.net/infestation#startup Jack (MVP-Networking).

Jack, I'm fairly confident this issue has nothing to do with McAfee because the one computer I could access also had the same version of McAfee running. Like I said, the issue seems to be related to Windows Internet Connection Sharing because the ip address of each computer is not coming from the router but rather from ICS. I'm not at the location where the computers are at right now but I'm thinking of trying to enter static ip addresses that correspond to the range the Lynksys router uses to see if that works. Even if it does I don't believe it will be an optimal solution as the ICS DHCP server will still be running and will keep people from accessing computers by name...if I understand this correctly. Another theory I'm considering is that the ICS Internet Gateway component is allowing one of the computers to re-enable ICS after I disable it. Windows XP's Internet Connection Sharing apparently allows an ICS client computer to remotely monitor and control the ICS server computer's Internet connection. I am wondering if that means it can automatically re-enable the connection after I disable it on the host computer. My other theory is that the router is somehow defective and that is why I'm not getting ip addresses from it.
