WIN7 & XP network access

[aem]

I know you said you disabled the adapter you don't want to use, as per your XP settings, but it's really hard to say what affect would work on W7. Can you pls enabled all adapters and make sure your drivers are all good.

 

[Spuddy]

When all connections are enabled all drivers indicate they are working properly.
I am not sure about the affect on the WIN7 machine as it has no network access yet but enabling the two connections at the same time ment I lost the internet access until I disabled the LAN connection on WINXP. As I had been told by my computer company having both PCL card networks open on the WINXP machine will cause a conflict.

From your picture, which interface are connected to each other? For example "To Pentium" in WinXP connects to "Local Area Connection 2" in Win7. If so, when you connect the cross over network cable, I assume both will say network (at least), network cable is connected. If Win7 still say "Network cable unplugged", then you have your self a straight cable, not a cross over.

 

[Spuddy]

If you look at the pictures WINXP (to pentium) connects by cross over cable to WIN7 (Network Sweet). I understand WIN7 will automatically disable any unused networks. Before WIN7 I had WINXP to WINXP networked and functional for years, the hardware has not changed in this equation just the introduction of WIN7 OS on one machine.
When the LAN is enabled the WINXP machine states network connected and the WIN7 states "no network access".
Funny thing when I just turn off the WINXP machine (networks hardware joined still) the WIN7 comp taskbar icon goes out and the 1st two sections on the 'Network and Sharing Center' page change, my deduction is that WIN7 comp can see the network its just blocked somehow.
Again thanks for any input, like someone said it will be a simple solution.

No ideas?
I was wondering if any one knew any other technical Win7 and or networking sites that might offer a solution to my problem.

The disabling of networks/adapter is not a default setting. When you build from scratch. The OS does not do this untill you configure it to.
The linkage between the machine's network connections is done after the OSs are build so these happenings are due to some setting made by you (has to be). Settings like NIC bridging, teaming or even firewall can effect the entire network. We just don't know your setup as much as you do.

Just thought I would add this to the thread. The information about perhaps not needing a cross over cable and the note about if Gigabit ethernet is involved that a different type of cross over cable is needed was interesting. Otherwise is seems pretty straight forward. Or not.
Connect two computers using a crossover cable

I cannot find anything more simple than linking two machines together with a cable. Get back to the basics, none of these Homegroups, WORKGROUP things. Has worked for me. Matter of fact it has work for generations of Windows. Abit of Networking basics goes a long way i tell ya.

Today I hooked up another computer (my 3rd computer) with WINXP on it (I have used these two networked successfully (WINXP to WINXP) together before) to my WIN7 system. Now this setup is very basic and perhaps shows the worry people have (previously in my tread) about disabling is unfounded as it also fails to network.
Here it is:
WINXP to WIN7 crossover cable directly to each others PCL cards. WINXP states connected, WIN7 no network access. (WIN7 system has always been set at default now and with previous WINXP comp.) There is only the 1 network adapter (on each machine) at play here and no internet desired or connected, no modems or routers.
I tried two setting options here:
1. Everything default on both comps "obtain an IP address automatically"- result both say no network connection.
2. "Use the following address" (manual IP) - result WINXP says network connected, WIN7 says no network access.
I should have posted only with this simple setup as my previously posted setup has thrown everyone. So the basic problem I cant connect WINXP to WIN7 with a crossover cable. I have proven there is no hardware problem (years of previous use). I feel WIN7 is causing the conflict when set to default what do you suggest I change to gain access.

Spuddy, ignore Windows 7's "No Network access" message, assign an IP address to both of your PCs. Assign 191.168.0.10 for Windows XP, and 192.168.0.11 to Windows 7. Now, disable both firewalls, ping each other. If you don't know how to ping, here's how: press "Windows + R", type in --> cmd /k ping 192.168.0.11
on the Windows XP machine, see if it replies.

IF IT DOES, then in Windows XP's Explorer address bar, type in this --> \\192.168.0.11
It should ask your a username AND password, fill in your profile's username and password on the Windows 7 (if your profile doesn't have a password, create one - this is nonnegotiable).

The other way around, open Explorer in Windows 7, type in this --> \\192.168.0.10
It should ask your username AND password, fill in your profile's username and password on the Windows XP (if your profile doesn't have a password, create one - this is nonnegotiable).

This should fix your sharing problem.

Excellent point...Now you have me wondering if perhaps the installation of Win7 and it's subsequent driver installation for your network adapter may have either added some features that weren't present before, (like the infamous task offload issues) or perhaps and maybe even more likely is causing problems with auto negotiation, maybe you can try setting the Win 7 end to 100 full or 100 half, or maybe match them up on both ends. Just another thought.

Thanks zzz
I applied your settings as instructed , leaving default gateway and DNS empty (hope that was OK).
I pinged but it timed out. ???

 

[Spuddy]

The drivers for the WIN7 computer were downloaded and updated from the Realtek site WIN7 64 bit drivers, they indicate they are working fine.
Pat I don't know about 100 full or 100 half (googled but no joy) can you give me a walk through.

Leave it empty, you need to fill "Default Gateway" ONLY IF you need to access an external network (example: internet). Disable BOTH Windows XP and Windows 7's Firewall. Re-ping.

100Mbps Full Duplex/Half Duplex only states that you can have 100Mbps up AND down (Full Duplex), or 100Mbps up OR down (half duplex).

The difference is, you can only transfer OR receive (half duplex), you can transfer AND receive (full duplex). It's an Old network terminology...

zzz,
I had turned off all firewalls in both computers in the failed ping above. Thank you for the actionable suggestions though. I know this is just a tick the box solution, its just tricky finding that box.

 

[zzz2496]

Disable other network interface, re-ping. If it still not ping/ponging... I suggest you look/use another network interface (IIRC you have more than one network interface). Some hardware just doesn't want to work with Win7 for whatever reason (I have an old realtek LAN card, in XP it runs fine, in Win7... it just broke for no apparent reason, probably the driver).

Before you test using another Network interface, make sure you write down the configuration before applying mine.

I have used the WIN7 computers same Ethernet LAN port for an Internet connection, directly connected to the modem and had perfect internet connection, this was for up dates and through a firewall. I feel the Ethernet driver is working and its a mother board only 1 year old: GIGABYTE EP45-DS3.

 

[zzz2496]

Spuddy, just do whatever you can to make both can ping each other (windows 7 can ping windows xp, and windows xp can ping windows 7). If the network interface are OK on both computers, change the cable. All I need for you now is so that both of your computer can ping each other.

Spuddy, here are some guides that you can use to check if your cable is a cross or straight:

ethernet crossover cable diagram and functionality
How to Make Your Own Network Cables - Network Cable Color Code Standards

Check your cable, make sure it's cross. If your cable is cross, and is operational normally, your computer should be able to ping each other just like that (provided that you followed my IP addressing guide, and both windows only uses the active network connection, that's why I need you to disable other network connection, just in case.). Once your computer can ping each other, all you need to do is put a password on both computer's account, and \\[ip_address]

Hope that helps
