Network 2 Computers

[Jeff242]

I want to connect 2 computers for 1 gigabit lan file sharing. I have both 1000mbit ethernet jacks connected with a CAT6 Crossover cable. I ran Network setup wizard on both computers. The host computer says the connection is fine and at 1 gbps. The 2nd computer says limited or no connectivity. I press repair and it says it can't renew the ip address.


Please help me.
A step by step on how to do this would be great.
Any and all help is welcome

Jeff


A clear explanation of the problem you are having
What doesn't work: The second computer in my PC to PC network has a yellow triangle w/ an explanation point in it and says " Limited or no connectivity" . Also I am guessing that the name of my other computer should be in "My network places/Entire Network/Microsoft Windows Network" but it is not-I only see the computer I'm on. And third, I am also guessing I should be able to connect to the internet on the 2nd computer through the main computer, which is connect to a cable modem, because when I run the network setup wizard on each machine it asks me which on is connected to the web and which one is connecting to the net through another computer.

What does works: On the main computer, when i go to Network Connections in the control panel, The network adapter which is connect to the 2nd PC shows that the connection is fine and running at a full 1gbps.

What you've tried: Using a CAT6 crossover cable. Bought a second PCI Network Adapter "10\100\1000" and tried connecting that to the main computer, but sill had the same "Limited or No Connectivity" message.

A description of your network -I have a audio software program which streams digital audio and MIDI between 2 PC's to allow another PC to be used for audio processing and returned back into the host program on the 1st PC so that the processing load can be shared.


Whether its dialup, cable, dsl,... : I have a broadband cable modem connected to a Pci 10\100 card in the 1st PC. Then the 1st PC also has a Gigabit network adapter thats built in to the motherboard, and I use that Jack to connect to the gigabit jack on the 2nd PC via Cat6 Crossover.

Whether you have a router, and if you do then what model it is: No router

Do you have multiple PCs networked : Yes, 2 computers networked directly together (PC to PC)

Is it wireless or not: No

Are you using Internet Connection Sharing (ICS): I think so. I dont need it but i figured this will be one way I can be sure that the pc's are talking.

The OS(s) you are using

Windows 98 (SE) :No

Windows XP (SP1, SP2) :Yes SP2

linux (redhat, debian,...) :No
What do you have for an IP address?
Run "cmd /k ipconfig" (either in a DOS command window or using Run... from the Start menu
A bad IP address is 0.0.0.0 or 169.254.?.?
If you have a router, a good IP is usually 192.168.0.? or 192.168.1.?
This is from the Main Computer (one thats connected to the internet):

What is your default gateway?

Run "cmd /k ipconfig"See Above

Can you ping your default gateway?
Run "cmd /k ping IP_ADDRESS_OF_DEFAULT_GATEWAY"
Ill let you all interpret this:

For a cross over cable that is normal activity. Windows doesn't have a built in DHCP for computer to computer networking... instead it issues default ip addresses. If the computers have ip addresses of 169.254.x.x you should be fine.

[Jeff242]

But am I right in that I need a crossover cable. I read that to make a simple two computer network, i need to use a crossover cable to connect the 2 computers, and also its says right on the box: "Crossover Cable, For connecting PC to PC or Hub to Hub."

Also, once I get the network up and running, how do I access the files on the other conputer???

Jeff

[Archangel122184]

Yes... when connecting directly between 2 computers, a crossover cable is your only option. As for how you find your files...

You can use the UNC (start->run->"\\computername" ) or you can use the IP address (start->run->"\\ipaddress" ) or you can use "My Network Places". The if both computers are XP they should be able to discover eachother.

[z1p]

If you stay with ICS on PC1 (in the network connections view your icon for the connection to comcast should have a hand on it) then on PC2 make sure it is set to obtain its IP address automatically.

[Jeff242]

So I read in another forum this:

-Set PC1 IP address to 192.168.0.1 and PC2 to 192.168.0.2 (last number different)

-Set Subnet Mask on BOTH to 255.255.255.0



I did this and the second pc now says connected!! BUT, here;s the big but:

-when i go to my network places-->Entire Network--> Workgroup (I named it STUDIO on both machines), I only see the computer i'm on and not the other.

-I went to pc2, set the main disk to be shared over a network and gave it a name, went to pc1 and in win explorer i did a search using the name of that drive, nothing was found.

-start-->run--> type:\\"PC2's Name"----says network path not found

So even though both network adapters say they're connected, I can't access the other computer in any way

What do ya think?

[z1p]

Ok few things.

1) share a folder not just the main disk drive. XP will sometimes give you trouble sharing a full drive.

2) check the firewall on both machines

3) trying pinging the machines from each other

[Archangel122184]

Here is some information on setting up file sharing

Windows 2000 (http://www.wellesley.edu/Computing/FileSharing/Windows/win2kxp.html)
Windows XP (http://www.practicallynetworked.com/sharing/xp/filesharing.htm)

Let us know if you have some problems with that.

I am concerned that when you used the UNC ( \\pcname ) you got an error network path not found. Even if the computer had no shares available you would still have been able to see the computer unless something was wrong.

Check to make sure your firewall are disabled or are configured to allow file sharing.

3) trying pinging the machines from each other

Ok so give me the steps on how to this one, PLease:happy:

There is nothing new that I haven't already read, besides, I'm looking for something specific on PC to PC networking only

YES, thats my problem in a nutshell. I can not see the other PC in my network. Thats what I need help with!!!!




Check to make sure your firewall are disabled or are configured to allow file sharing. I have turned off the firewall so that on both PC's it says "Connected' and not "Connected, Firewalled"
Still no dice when I Run "\\PCName"

[Archangel122184]

On both computers goto

start->run->"cmd"->enter->"ipconfig /all"->enter

Post up the full output for both computers if you can by right clicking on the title bar of the command window and clicking edit, select all, then edit, copy... you can then paste it where ever.

Just a note: you can use ICS to share the internet connection with MRS-COMPUTER. All you have to do is set the adaptors that are being used to connect the 2 computers together back to automatically obtain and then enable ICS. Windows XP ICS (http://www.practicallynetworked.com/sharing/xp_ics/serverbroadband.htm)

Lets try to get this fixed first though. It looks like your configuration is just fine. On mr-computer I want you to ping MRS-COMPUTER and on MRS-COMPUTER I want you to try to ping mr-computer
from mr: ping -a 192.168.0.2 (the -a will try to resolve the host name)
from MRS: ping -a 192.168.0.1

If these are successful, instead of using the host name to connect to the computers, use the ip addressess ( \\ipaddress ). If they are unsuccessful there may be a problem with the physical connection.

Ok it looks like you have basic network connectivity between the two machines. Now, lets see about file sharing.

On both machines run 'net view' in a command window. Also, check your firewall again. It seems like the XP firewall sometimes has a mind of its own.

[Jeff242]

This looks good!!! After I turned off Win Firewall I found the icon for the other computer in MY Network Places.

Rather than having to save the text on pc2 and burning to cd-rw so i can post it in this forum, I saved it in the shared docs and accessed it on pc1

So, there were 3 things that i wanted to do with this network
1. share files- done

2. Use FX Teleport, a software program that sends digital audio over LAN to share processing load...It finally recognized the connection and is working, DONE!!

3.Access the internet on pc2 thru pc1, not working


So now all we have to do is figure out why Web pages won't load on internet explorer on pc2.

Take a look at the network adapter settings on pc2 check to make sure the dns server ip addresses are right. I believe your dns ip's are:

DNS Servers . . . . . . . . . . . : 68.87.69.146
68.87.85.98

On pc2 try to ping an outside domain for example ping google.com and see if it times out or you get results.

[Archangel122184]

Its always the darned firewalls...

As for the internet connection

Just a note: you can use ICS to share the internet connection with MRS-COMPUTER. All you have to do is set the adaptors that are being used to connect the 2 computers together back to automatically obtain and then enable ICS. Windows XP ICS (http://www.practicallynetworked.com/sharing/xp_ics/serverbroadband.htm)

If you are already using ICS, just goto MRS-COMPUTER and set the default gateway to 192.168.0.1 and the DNS server to 68.87.69.146

whoops, sorry to post over top of you... But looking at the ipconfig information, PC2 doesn't have a default gateway or dns server set.
