Can't access network pc (2 nic)

Hey there.

This week I got this problem with my network connections, I can't access a network pc. Even though I can see it on the explorer, I get the 0x80070035 error whenever I try to access it. About two days ago everything was working ok, I was able to access both computers with no problem at all but this last Win update must have done something to my conn.

I'm running Win 7 Ultimate on both comps, my main's MB is an Asus striker extreme and it has two nic's, one is connected to a cable modem (thomson thg540) and another to my second comp, all connections are wired.

What happened so far:
The connection between my two comps used to be an unidentified connection when it used to work strangely, after this whole problem started my secondary comp lost its internet connection but was still able to access my main comp, my main lost its ability to connect to my secondary even if I could see it in the explorer giving me the 0x80070035 error as you can see below.

Error


I checked their IP adresses and noticed they both had 169.254.xxx.xxx adresses so I googled the problem for a bit and gave both pcs a static IP like you can see below.

Main pc


Second pc


After I did this my secondary comp was able to access my main and get internet access but my main still wasn't able to access my secondary comp through Win explorer, it still gives me the 0x80070035 error. I've checked all services and whatnot and everything seems to be working ok, I have the same workgroup in both comps, sharing settings are set properly, sharing privileges are set properly, win firewalls are down, no anti virus software installed, when I ping my second pc no packets are lost.

So the problem persists and I have no idea on what to do next...

If any of you guys could give me a hand with this I'd appreciate it.

Thanks for the reply Aem, as I said in my first post I have two comps, my main comp has two nic, one connects to my secondary comp and the other to a cable modem.

I used diferent gateways because if I don't I get an unidentified conn. That's the only reason... My second comp gets internet access and can access my main, my main comp gets internet access but can't access my second comp.

I was always able to ping pc 2 with my setup.

I tried your setup and pc2 lost internet connection and now has unidentified network between pc 2 and pc1. The setup I had was running fine except for the fact that I can't access pc 2 through Windows explorer even though I can see it.

Still have the same problem.

Thanks for the reply anyway.

If you suspect that Windows updates caused this problem than why not uninstall recent updates and see if it fixes the problem?

Also, if you were using Homegroups to share with you will need to renable IPv6 in network properties.

@ Chev, I did a system restore to a time prior to the update and everything worked fine that's why I suspected the update was the reason for this damn problem but when I uninstalled the update it didn't fix it only the Sys restore did for some reason and that restore point is gone so I can't restore my comp again...

@AEm Didn't notice your previous posts, gonna test them out and see what happens, stay tuned!

Tks for the replies everyone.

Some visual aids to make sure you guys understand how my conn is setup.



And the network maps.
Pc1 nic 1(internet)


Pc1 nic 2 (pc 2 conn)


Current situation: I have internet on both my pcs so internet conn is not the problem.

My problem is that I can access pc 1 from pc 2 from the win explorer but I can't access pc 2 from pc 1 and I get the 0x80070035 error.

@ AEM - Ok so I ran Ipconfig /all and this was all I got, the only thing I had connected at this time was my internet on pc1.



Not sure where to go from here, hope you guys can make something out of this.

Once again, if you are using Homegroups for sharing you need to enable IPv6. It won't work without it. You are using ICS with your dual NIC set up. If you don't have ICS enabled you should do so. It looks like the connection is shared so that might be done already. You might try a network bridge also. Although I'm not sure why you wouldn't just use a regular old router for all this?

You might want to check in the Advance Sharing settings to make sure everything is like the picture below. Sometimes they change by themselves apparently.
