Solved Win 7 Cannot Access one of 4 computers on LAN

mendopaul · Jan 21, 2013

I've tried every sharing thing I can including turning off the firewall and other services. I'm stumped. My main machine can "see" my AV Server and its drives but "cannot access....." any of the drives. I've shared with full permissions all of the drives and I've unintstalled and reinstalled File and Print sharing twice. I'm out of ideas. Other machines on the LAN are totally visible and can exchange files. I realize this is complicated but I'm hoping someone has thoughts or inspirations to share. Thanks for anything.

What antivirus are you using?

With the balky machine?

Have you tried rebooting it?

Hi there,

In addition, have you tried accessing the shared drive or folder using this method?
Click on Start and in Search programs files and files box type \\ComputerName\SharedFolder or \\IPAddress\SharedFolderName. Note that you'll have to do this from the computer that's having an issue accessing the network resources.

We'll appreciate an update.

Hi Parman, I'm using Norton AV and I've checked all the settings and can't see where any of them would interfere but, of course, I could be wrong. I can always disable NAV and see what happens I guess....haven't tried that yet.

Hi Sidowney717, No I guess I haven't tried yet to reboot it and will now and will get back to you shortly.

Hi 2XG, I think I have done this but I'll try once again and see what gives, thanks.

If you have tried what I have suggested to you and didn't work disabling Norton might help. Others have more luck on uninstalling it completely by using the Removal Tool, if you decide to reinstall it back you may do so.

Please give us another update.

Parman · Jan 22, 2013

I have to agree with 2xg, I would completely remove Norton to see if that fixes the issue. If it doesn't you can always re install but 80% of the time its good old Norton

mendopaul · Jan 22, 2013

Well, many thanks to all of you. It's made a difference. I rebooted (feel stupid for not having done that before now) after checking the other stuff you mentioned and NOW I can access my main machine from the AV Server.....which could not be done before this. I'll try 2xg's method of accessing the shared drive via the search box and if no change then I'll disable Norton, and then uninstall it completely and see what results. I'm feeling like the problem is now half solved and I'm close to solution thanks to your help! (Just to recap the remaining problem: I cannot access the AV Server from my main machine, "Access denied etc". Seems like that is where the remaining problem is located.

What kind of sharing are you trying to accomplish?

File and folder sharing
Turned on from the sharing tab of the file or folder properties
Homegroup sharing
Turned on from creating and joining a Homegroup
Public folder sharing
Files located in the Public folder.

Hi Parman, I'm only trying to move ordinary files around between my various computers on the ethernet LAN. In this latest case I'm trying to move some history courses ripped from DVD to my AV Server to stream the courses to our tablet where we can sit and watch them in comfort. I've not been able to move the files from my main desktop to the AV Server because of this "Cannot access......." problem. Now it's just in one direction that I have the problem: from desktop to Server. it works fine now in the opposite direction, from Server to Desktop.

Parman · Jan 23, 2013

The easiest way to share for home users is a homegroup, since the users folder is shared by default. If you're using the right click on folder < Share tab < share button method "File & Folder Sharing" You can edit the NTFS permissions adding authenticated users and giving them the modify permissions.

You should then be able to use your username and password of the AV server to connect.

I tried to enter the path in the search box on Win Start but it would not work either. Nothing seems to penetrate that machine's front end. I suspect it's still somewhere in the permissions or basic setup but I've not been able to find where. Again, the only problem I have is moving files from one LAN node to this one AVServer of mine. All the others work fine in both directions so other permissions are apparently ok.

New Info

WELL, turns out I'm incorrect! I just found that one of the computers on my ethernet LAN can indeed access this computer properly in all drives! That leaves my main desktop and my Laptop still unable to penetrate whatever is holding them out of this machine. This means that one machine is set up differently at its end of the connection or that machine is configured differently within the AV Server settings. Anyone have an idea as to what settings might turn out this way in different machines? Still a puzzler but getting more clues!

Parman · Jan 24, 2013

Have you uninstalled norton using the removal tool?

2xg · Jan 24, 2013

If uninstalling the Norton using the removal tool which I think might do the trick...can you provide us an ipconfig/all output of the AV Server and one problematic computer, a total of 2 outputs?

sdowney717 · Jan 24, 2013

Did anyone mention a firewall issue?
Turn it off on the machine your trying to enter.

mendopaul · Jan 25, 2013

I turned off the firewall in the AV Server and it made no difference in others' ability to access. I'll try to get the IP Config pictures that were suggested. So I uninstalled Norton using the removal tool and it made no difference. Restate the problem: One machine can access this AV Server completely but two others cannot. What's difference between these machines? I'll try and furnish IP Config prints requested.

mendopaul · Jan 25, 2013

Here are the IP Config results for the AV server that cannot be accessed:

And here are the IP Config results for my main desktop that cannot access the AV Server:

And here are the IP Config results for my wife's computer that is the only one that CAN ACCESS the AV server properly:

Thanks much for your effort uploading all the output. Here's what I found and discrepancies.

PK2010 – there’s no ipconfig/all output

AV-Server - DHCP needs to be enabled.
DHCP Enabled. . . . . . . . . . . : No (this should be Yes)

Nancy-06
DHCP Enabled. . . . . . . . . . . : Yes (this is correct)

Many thanks 2xg, I was hoping for a different answer but both computers read the same in those settings...identically. I can't understand why the ipconfig /allcompartments show that one is not set for DHCP. Any thoughts on this? I haven't checked my wife's machine yet......that's the one machine that CAN access that Server.
