Windows XP to WIndows XP - Network Problem
santle Dec-04-01 05:43 AM
I have a little problem on my hands ...

I have two computers running Windows XP Professional and they are both plugged into a HUB. I am also connected to tha Internet via aDSL. The aDSL is also plugged in the HUB. Each PC has one NIC installed. Now the problem arises
here, I can't see each PC in "My Network Places" or I can't find them when I search for the computer names using the Windows Find. They are both part of the same WORKGROUP, called HOME, and have unique computer names. Basically I have a simple home network setup but the PCs can't see each other. Both NICs have TCP/IP binded to them, no other protocol is installed on either PC. Client for Microsoft Networks is also installed on both PCs.
The part that blows my mind is that both PCs used to run Windows 9x and the LAN was working fine! Now with Windows XP Pro the only way I can see the PCs is mapping \\xxx.xxx.xxx.xxx\ and that routes through the internet first and
slows the transfer down intensly on the LAN! Can someone help me out with this? I do not want to have to resort to installing another NIC in one PC and share the internet via that, thats what I am trying to get away from.

Thanks.

Steve

what is the network configuration?

are you using dhcp....
if yes, which computer has dhcp running?

do you have a router? or hubs

You canít share the Internet with your configuration unless your ISP provides two IP addresses, and most of them charge a monthly fee for additional IPs. Or, you run software that can share the connection with only one network Adapter. I understand that the latest version of SyGate (http://duxcw.com/digest/Reviews/Network/sygate/sygate.htm ) can do that. As far as I know XP ICS cannot. See http://duxcw.com/faq/ics/waysshare.htm and http://duxcw.com/faq/ics/diffrout.htm.

Have you shared something (with names besides default one containing a $)? Are the guest accounts enabled? What are the TCP/IP properties? Was XP installed as an upgrade or was it clean-installed (http://duxcw.com/faq/win/xp/clean.htm)? I didnít say to reinstallÖ Larry

Well see, I have a HUB, not a ROUTER, and I have TWO IP addresses from my ISP. The Internet is plugged into tha HUB also. So both PCs in tha house have their own IP address and they are both plugged into the HUB and I can't see either PC in the Network Neighbourhood. The guest accounts are enabled and and only TCP/IP protocols are installed on both PCs. I don't want to share a internet connection, i just want to be able to access files on tha PC downstaies and vice verse. They both have their own IPs.

Please help

Thanx,

Steve

When you run ipconfig for the command prompte, wht IP addresses and subnet masks do you see? c:\>ipconfig /? will provide the command syntax. You might try installing the IPS/SPX protocol in addition to TCP/IP. Larry

When I run IPCONFIG on each PC I see the PCs individual IP addresses and a SUbNet of 255.255.255.255. COuld this be the problem? THe subnet? INstalling IPX/SPX on both PCs does not help the problem any I'm afraid, still no connection. help!!

Thanx,

Steve

The 255.255.255.255 subnet mask = 11111111.11111111. 11111111.11111111 yields IP address + subnet mask = IP address = subnet address = Internet IP. XP might be set to turn-off sharing while connected to the Internet or the XP firewall (new) may be enabled. I would have to install the drive I have XP on to check it. You look first, OK? Or, do you have another firewall running? However, now you are going to have a problem with those shares being exposed to the Internet, if another protocol does not work. Did you wait 15 Ė 20 minutes or search for PCs while IPX/SPX was installed? That is one advantage, besides not having to pay for second IP, of a good router (http://duxcw.com/faq/ics/diffrout.htm). It has a NAT (which is pretty good protection in and of itself) plus a firewall between the PCs and Internet. Larry

Hey guys I got it working, here we go!

Someone helped me out in another news group, hope this helps you guys! thanx for all the help just the same! =)

I still have a question tho, will the below setup work? I still want to keep my HUB in the operation so if I add a router will i be able to share all files on tha LAN privatly from the internet if I use the firewall settings on the router?

Check out this diagram:


Thanx,

Steve

It will work with one line (http://duxcw.com/faq/network/uplink.htm) between the router and hub; however it is unnecessary. Most routers have a built-in firewall. And most are Ethernet switches, which are faster than your hub. The SMC 7004BR Barricade (http://duxcw.com/digest/Reviews/Network/smc/smc7004br/smc7004br.htm) has an excellent firewall that I prefer to any software solution. I have used the 7004BR for a long time. Now I have the 7-port version, 7008BR. Both are very good products. I have not used the latest 4-port version (7004ABR) of the Barricade. Suggest selling the hub; thatís what I did. Thank you for taking the time to write-up you experiences. Larry
