I have a total of 4 computers in my home and have them all on the same network. Here is the break down of my situations.

Computer A: Desktop computer running windows vista, wired connection to router, HOME workgroup. Can access all computers on the network.

Computer B: Desktop computer running windows xp, wired connection to router, HOME workgroup. Can access all computers on the network.

Computer C: Laptop computer running windows 7, wireless connection to router, HOME workgroup. Can access all computers on the network.

Computer D: Laptop computer running windows 7, wireless connection to router, HOME workgroup. Can ONLY access computer B and C....Computer A shows up but I get an error message while trying to access it....\\pca-pc is not accessible. You might not have permission to use this network resource. contact the administrator of this server to find out if you have access permissions. The network address is invalid.

Now computer C & D are in the same workgroup because they are both windows 7, but while computer C can access computer A, Computer D can't???

I've made sure they are on the same workgroup. I opened command prompt and typed ipconfig all and they all have the same IP. I've changed Computer A's computer name. I'm at a loss and I don't know what to do.
So if someone can help me, let me know what information you need and I will gladly supply it. There seems to be something wrong with just Computer D the windows 7 laptop. I recently did a system restore/recovery just to make sure it wasn't a bug but still problem exist.

EDIT: Forgot to add all computers are updated completely via windows update. More information I forgot to add, I've looked at all windows firewalls to make sure files and printer sharing were listed under allowed, I even turned firewall temporarily off. Still no go.

Please show for Computers A and D ...

Start, Run, CMD, OK to open a command prompt:
(For Vista or 7 type CMD in the Search box after Start)

Type the following commands:

nbtstat -n

IPCONFIG /ALL

[Note that there is no space between the slash and ALL.]

PING <name of the other PC>

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If necessary use a text file and removable media to copy the results to a computer with internet access.

Because of the last part of the error message you get ("The network address is invalid") I was hoping that the above output would give some clue about what's happening. But it all looks good to me.

If on the Windows 7 machine you click on Start and type

\\Christina-PC

and hit Enter I assume you get the same error you quoted above. If not, what happens?

Also try

\\192.168.1.21

What, if any, non-Windows firewall or security suite is, or was, on either of those machines?

Yes by typing \\Christina-PC I get the same error message.
When I typed \\192.168.1.21 username and password box came up at which I typed correct username and pass and that worked!!! But why isn't it working the other way?

All computers are using the window default firewall, all computers have file and folder sharing on allow list. I have temporarily disabled virus scanners, adaware scanner, even windows firewall to no avail.
Also I'm wondering about Computer D's Local Area Connection 2 and I checked I also have Wireless Network Connection 2 and 3. Do I really need all these? should I disable them?

Don't know. When I asked for the original input I thought that we might see that one of the computers had two connections to the router (maybe wireless and ethernet) or that when the Windows 7 pinged the Vista it was using the IPv6 address. Neither is true. Just had an idea--doubt it will be a cure, but won't hurt; in a command prompt on the Windows 7 (Computer D) type

ipconfig /flushdns

Initially (for up to 20 minutes) it may not know the names of the other computers, but maybe it will help once the names are repopulated.

Also I'm wondering about Computer D's Local Area Connection 2 and I checked I also have Wireless Network Connection 2 and 3. Do I really need all these? should I disable them?
LAN 2 is WiMAX; don't know if you use it. The wireless 2 and 3 are virtual miniports. Doubt any of those are causing this issue, but wouldn't hurt to try disabling them.

Ok I disabled LAN 2 and Both Wireless 2 and 3. Restarted the comptuer and no change...

Just did the flushdns will wait about half hour or so and try it again. Will post back with results.

On computer A I would create another account with the login name and password used on computer D. Computer A doesn't have to be logged into that account, it just has to exist so the computer recognizes the user.

Also, is the error still "//pca-pc/ is not accessible" ? Since that's not the name of the machine, that's a problem. AFAIK, on a network, one machine will keep the list of other machines on the network. Other machines will look to that machine for the list. If I'm correct on this, I would try the flushdns command on all the machines.

Along this line of thinking, I've solved some networking problems by shutting off the "computer browser" service on conflicting machines.

Dvom I used \\pca-pc\ as example I know that's not the correct name. That was just the example I used to explain the error message.

EDIT: What I don't understand the most of all this is they were ALL connected perfectly until I did a system restore on computer A but consider other computers can connect to computer A just fine it makes me think there might be something wrong with computer D?

Just got down talking with HP, The suggestion they gave me was to run cmd as administrator and type in "net user administrator /active:yes" After restarting the computer I logged into the new administrator account but still couldn't access the shared files and folders, I switched over to my regular administrator account and it WORKED! I was able to access the shared files and folders. But now I have a dumb administrator account user on my windows welcome screen and thought to hide it by going to cmd running as administrator and typing in "net user administrator /active:no" So now that silly administrator account is hidden and again I cannot access the shared files and folders.

I just don't understand it, I was able to access these files are folders just fine in the past without having this dumb administrator thing up on the windows welcome screen and now I have to have that active. It just doesn't make sense. Is there anything else I can do to fix this situation that I am having?

Is that on the Vista or the Windows 7 that you need the special Administrator account active?

Is the account name that you use on the Windows 7 also on the Vista? Also on the other Windows 7 machine?

It's the windows 7 that needed the special Administrator User active.
All computers have unique username and passwords and when I click on a computer in the network I just login with the username and password associated with the computer.

Example: If I'm on computer B and I login to see the shared files on computer A I use Computer A's username and password. It's always worked like this for me and suddenly stopped working when I did a system restore on Computer A. I also did a system recovery on Computer D shortly after.

So therefor I'm unsure which computer initially had the problem but now I'm thinking that because all the other computers can access computer A just fine except the windows 7 laptop then it must be the windows 7 laptop.

Activated that Administrator User fixed it but I never had to have that activated before. So what could this mean?
