Here is the PROBLEM:  No folders show up on my Laptop under "My Network Places".

Everything was working fine up until yesterday, when I clicked on a song from another computer through my network places, the song began playing, and then the window for MNP just disappeared.  From that point on, when I reoppened MNP, nothing would show up, not even the shared folder on the laptop.

Host machine:  Wired DIRECTLY into the router (Netgear).  Running Windows XP Pro completely updated.  It can see it's own folders and not the laptops.  This machine is able to ping the laptop.  Zone Alarm firewall has been set up to allow ranges 192.168.1.2 - 5.  Windows Firewall is Off, completely, from what I can tell.  Had to disable it on my Local Area Network, not sure how it got enabled.

Laptop:  Connected to Router via Wireless Adapter (Netgear).  Running Windows XP Pro completely updated.  It can not see any folders in MNP.  There is absolutely Zero Firewall protection on this machine.

I have tried numerous solutions from many forums, none of which have worked.  Although,someone did suggest trying manipulating with the TCP/IP Protocol, by adding IPX or something.  I added Microsoft TCP/IP v6 I think, to both machines, and now I am able to ping both sides, and can manually type the addresses of the shared folders and get access.  Yet, MNP still shows nothing, and keeps telling me that it can not access Mshome, not having the right permissions or some nonsense.

I was also having Some kind of NetBT Error 4321 in the event viewer, which I seem to have fixed via registry by changing something domainmaster to false or something, I can't recall as this has kept me up all night and my mind is not working properly.  I know this probably isn't a major problem, but the simple fact that something is not working properly makes me wonder what is truely wrong.  I would like to fix this, but after spending probably too many hours on this, with no luck, I am hoping someone knows what is wrong.  Thanks guys, any help is greatly appreciated.

Please accept my preemptive appology if this is posted in the wrong place, I am new here, and I did not see a Networking Section.  Norfalk:

You have given two computers on your network the same "name":

http://support.microsoft.com/default.aspx?scid=kb;en-us;822659
http://support.microsoft.com/kb/316836/EN-US/

Make sure each has a unique NetBIOS name.

I actually checked that, and the host machine is named "Master-Bdrm" while the Laptop is cleverly  named "Laptop".  But then again, I really don't know squat about networking.  Is the NetBios name diferent from the computer name?  I have never gotten the Error Message,"Duplicate name exists." When the computer starts up as the KB suggests.  Also, the error has stopped being reported.  I found on another forum that it also has to do with the computers competing to be the Master Browser or something, so I made changes to the registry that were suggested.

The Network worked great up until that MOMENT everything vanished.  I really appreciate the time you have spent replying to me.  Before I try the netbios thing that Microsoft has suggested, I WANTED to be sure that I really need to do it do you think I do?Norfalk:

Try to repair the network connection on the laptop:

1. Click the Windows Start button
2. Right-click My Network Places and click Properties
3. In Network Connections, right-click the icon for your LAN and click Repair
4. If you receive any error messages, let us know what they are


Best regards,
Doc
Sorry if I forgot to mention, the computer still gets onto the internet, as I am on the Laptop in question as we speak.  I can also get to the share folders on the other machine if I happen to remember what the location address is and manually type it in.  Everything seems to work, not sure how well exactly, but nothing shows up in My Network Places. If there is anything I have not added that is needed, let me know.OK, try mapping a network drive:

1. Right-click My Network Places and click Map Network Drive
2. In the Map Network Drive dialog box, enter the drive letter you want Windows to assign to the folder in the Drive list.
3. Type the path using the UNC in the Folder box, or click Browse to browse to the folder on the other computer
4. Select the Reconnect at Logon check box
5. Click Finish

Best regards,
DocOk using the mapping, I am able to get to to the folders on the other computer.  Still nothing showing in My Network Places.  Why doesn't it refresh the folders?

I just clicked on View Workgroup Computers and got the error message:  

"Workgroup is not accessible.  You might not have permissions to use this network resource.  Contact the administrator of this server to find out if you have access permissions.

The list of servers for this workgroup is not currently available."

That has been a constant through out the entire day/night/day, regardless of whtever I have tried or accomplished (not much)Norfalk:

Make sure you log on to both computers using exactly the same user name and password.
