Windows 7: I've seemed to have lost my network.

19 Dec 2016   #1

Windows 7 Home x64
I've seemed to have lost my network.

I've seemed to have lost my network.

First I have three computers on my network.

Computer A - my main one - a Windows 7 desktop
Computer B - a Windows XP desktop
Computer C - a Windows 7 laptop

On Computer A, I have my printer connected and shared but that's it. On Computer B, I only have one folder shared and used the printer through Computer A. On Computer C I have nothing shared but use to access my printer through A.

I've had this setup for almost 4 years and all of a sudden it's like my entire network vanished. My Internet still works. I have a cable connection and both desktops are wired into my router. The laptop connects wireless.

On Computer A I had the shared folder from Computer B mapped as drive (Z:). Then about 3 days ago I tried to access Z: and haven't been able to. When I clicked on the Z: drive I would get the following error message:

Network Error
Windows cannot access \\MYROOMXP (name on computer B)

Check the spelling of the name. Otherwise, there might be a problem with your network. To try to identify and resolve network problems, click Diagnose.

Error code: 0x80070035
The network path was not found.

The Diagnose button did absolutely nothing. It just said something about the Diagnose Service not starting but in the services in Control Panel it's set to Automatic start.

So I went to Computer B and I didn't try to access Computer A because I never could do that anyway. But I did try to print a file but it wouldn't go through.

I checked online and tried what suggestions where available including making sure all the services where enabled. Some where not but this never made a difference before so why should it now.

I tried the following:

deleted the Z: drive share. Removed the sharing options from the printer and from folder on B.

Even reinstalled network adapters.

Disabled Firewall.

Made sure all adapter components where installed

Disabled simple file sharing on both computers.

Deleted the saved Windows Credentials.

I deleted the printer drivers from Computer B and tried to reinstall them but now it can't see my printer at all.

I searched for any Microsoft 6to4 adapters to remove but found none as suggested by one post.

I can successfully ping each computer. From A to B and B to A and so on.

Deleted the following keys; HardwareID and Store from HKLM\Software\Microsoft\MSLicening, as according to one post.

Disabled the Firewall through services and flushed the DNS server.

One post suggested to go to the adapter properties and uncheck the Internet Protocal Version 6 (TCP/IPv6). When I did that the first time for a brief moment I could see but not access all my networked computers on my Computer A. When I did this it I got a pop up box asking if I wanted to Enable Network discovery and I said yes and then it asked did I want to enable printer and file sharing on a public network.. I wish I'd took some screen shots...but anyway it didn't make any difference. I restarted and it was all gone again.

So I tried a second time as I'm writing this. Before On Computer A for the Network I was at least seeing Computer A and the printer share and now it's completely gone. Nothing showing up on my other computers either. Does anybody have a clue what's going on here because I sure don't?

One final note, I don't know if it's related or important but when I right click on a folder on Computer A my main Win7 one, in the properties, I have no sharing tab on any folders.

Make sure all PCs have NetBIOS running disable ipv6 it's not used anyway network discovery should be on and the network should be private check all PCs

Just a comment.

Regarding to computer upon booting and has error.

Try to remember what each computers did before shutdown.

Such as any issue &or abnormal during shutdown.

From here, then you can zoom in to which computer had problem in shutting down.

Also, any issue also including installation of program &or application is done.

The problem could lies in one of the computer that can passes the error into the network.

About using Z:\ drive letter, it is no so good to use the last alpha to assign to a partition.
Sometime it is the Windows system that have assign this Z:\ drive for something else.

Most users tend to use Z:\ drive letter to assign.

The best way to assign driver letter is to use the middle character of the alpha.

Most Windows &or other application & program, do use the last few alpha for something else, not character in the middle of the alpha.

My guess is the conflict is there, so errors will keep pop-up whenever it wish to.

Windows 7 Home x64

Thanks for the replies but it didn't help. I could never access my windows 7 computers from my XP one. And I couldn't get the Windows 7 ones to communicate directly. So I set up the shared folder on the XP one that both Windows 7 computers can access. I don't really use Computer C much, it's more of a family computer so not important if that works or not, but it does. I can access C to B. So my problem seems to on computer A. I've tried every fix I could find online, even reset my router. No dice. I'll keep you updated if I ever get this cleared out. This is not a new network by the way. I had this set up now for almost four years including the Z: and except for an occasional glitch, this is the worse it's ever been.

I downloaded the program as samuria suggested but it didn't work. It was able to detect my other computers but it still didn't clear out the problem. Computer B and C can communicate but Computer A can't. I don't really care about C because I rarely use it but I do want Computers A and B to talk to each other. Using this program on both computers, they all see all 3 computers on the network and Computer A is the Master browser. In Windows Explorer computer A can see all three computers but when I try to access them I get the error message: Error code: 0x80070035 The network path was not found. Using the same thing in Computer B. The program NetBscanner can see computer A but Windows Explore on B cannot see A.

Windows 7 Home x64

I have a program on my system called ERUNT. It automatically makes a backup of my registration database every time I turn on or restart my computer. I was going to do a full image restore but then I wondered if doing just a registry restore would work. Usually I delete the older backups, right now they go back to 11/28/2016. I'm not sure when this problem started but I decided to use a backup that went back to 12/3/2016. The third of this month. That worked. Worst thing is I still don't know what happened and it might happen again. And I hate that, not knowing what went wrong in the first place. System restore on my computer seems screwed up since I seem to have restore points going back to 2012 that shouldn't exist. Anyway, thanks for the support.
