Networking 2 PC's - Firewall/protocaol problem?
I have recently purchased Dell Dimension 8300 that has an Integrated 10/100 Pro Ethernet network card. Runs on Windows XP Home Edition.
Also have a somewhat older (!) Dell XPS T600 (processor upgraded to 1200 with powerleap) that runs on Windows 98. This PC has a Belkin 10/100 Ethernet Network PCI card
I run the 2 computers separately and they both run McAfee firewall/antivirus/spamkiller software. As we only have slow circa 32k dial up available in our village (no prospect of broadband here!) they currently connect to the internet independantly via telephone adaptor on same phone line. Only one on-line at a time.
I want to network these 2 PC's but do not want to have all internet coonections going through one machine - I want to continue with separate dial up approach firewall/antivirus/spamkiller approach.
Bought crossover cable and linked machines up and ran network wizards etc. clicking box for independant internet dial up.
Have encountered problem re visability of computers on network - cannot "see" the other computer on the network unless both firewalls diabled.
For me to be able to "see" both computers on the network on each computer it seems that I have to disable the firewalls on both machines! Is there a way around this - ie identifying what to "allow" through the respective firewalls safely so that firewalls can continue running? Should I have set the network link to different protocaol for networking ie non IP protocol?
Any ideas appreciated - getting there slowly!
many thanks in advance

I'm going through the same problem as you. I'm trying to network my 8300/winxp with an old computer running win98se except i'm trying to run them both on a cable modem. I never thought it would too difficult since the router i purchase listed it as 3 easy simple steps of installation. That 3 easy installation steps made my head spinned like crazy. I'm still lost.
Goodluck,
chris

Yes this will work - but you need to check/set a couple of things first :
(1) Ethernet LAN - effectively your crossover cable is a very small point to point LAN, whcih is fine, but you need to make sure that both PC's have an IP address in the same subnet - otherwsie communciatiosn will fail. Ensure that both PC's are setup up for DHCP - Assign address autoamtically". Now you don't actually have a DHCP server involved here - but windows XP will use its AUtoDHCP function - which means - "no one has offered me an IP address via DHCP - so I'll choose my own out of the 169.254.x.x range"
Both PC's will do this and just check they match range and subnet mask - the "default router IP address will be blank and is normal in this scenario.
N.B. You could also use static IP addressing here - if yor familiar with how to do that, and just set 10.1.1.1 /255.255.255.0 and 10.1.1.2/255.255.255.0 on each PC respectively.
(2) Now go to your firewall s/w and ensure that a "trusted scope or zone" exists for these subnets or excat IP address....i.e. Trust 169.254.1.0 or trust 10.1.1.1.1 and 10.1.1.2 as examples
(3) To do yor final check - do "Start -> Run -> cmd" and enter in the black window box " ping 10.1.1.2" - if yor sitting on PC1....and vice versa on PC 2
You should get the "Reply in x ms" as a response if all is working well

Hi, i agree with the comments made by Sentinel, but just as to reduce the complexity of the whole issue (not knowing what you technical level is...), maybe you should disable your firewalls considering you don't have any of these machines currently connected to the internet, then sort out the network configuration first as outlined by Sentinel. Once this is all up and running, then proceed to configure your firewall using the last part of Sentinel's comments.

Sentinel,
That was very helpful, Thanks now i got my dim 8300 flowing the juice out of my cable modem and the router with the old pc. Both pc's are connecting. How do i fix this little problem, each time i play a streaming media over media player 9 i get disconnected from the router and same goes to the old pc. I did what you said and that was to disable both firewalls on both of the pc's. They connect fine on the net but the router doesn't seem to recognize media player 9 and disconnects itself. Media player 9 is already configured automatically for the net.
