We have a network setup here that connects six computers, I believe. Everything was working great until an issue caused us to reformat the C drive and to reinstall Windows XP Pro on the server computer. After installing everything back onto the computer, we decided it was time to get it back onto the network. However, we can't seem to be able to do that. I've been reading various sites for the past two days and trying everything I've seen recommended. Nothing seems to work. The other computers can all see each other, but they cannot see this computer nor can this computer see any of them. This computer can see itself.

Things to note:

- Windows Firewall is disabled.

- I can ping the other computers' IP addresses, but I cannot ping their names.

- I cannot connect to any of the computers using "\\<IP Address" or "\\<Computer Name>"

- The server computer was using a static IP before the reformat (when everything was working) and is using a static IP now as well.

- Enable NetBIOS over TCP/IP is on now as well. I don't think it was turned on before the reformat. It is not turned on on any of the other computers (though I have tried enabling it on one of the computers to see if it would work).
* "ipconfig /all" says it is Disabled.

- Here is a copy&paste of "ipconfig /all". It also says DHCP is disabled, though I'm not sure if that has any relevance (I'm not very good with networking stuff).

I'm stumped.

Have you used the 'set up a home or small office network' wizard on the server computer yet? Make sure it uses the same network name (mshome by default).

[ckile]

I have quite a few times, yes. The workgroup is the same.

Turn off any firewalls for debugging. If the firewall is the problem, you'll have to configure it to allow access to "trusted zone" addresses. Note that some firewalls must be completely uninstalled to stop them from affecting your networking.

Hold the Windows key and press R, then type CMD to open a command prompt.

In the command prompt window that opens, type type the following commands:

PING each remote computer by IP address, and if successful, PING by name. Open a command prompt as described above and type.

PING <ip address>
or
PING <computer name>

Where:
<ip address> - is the x.x.x.x IP address
<computer name> - is the computer name

A failure to PING is almost always a firewall configuration issue. Any failure to PING needs to be corrected before you go any farther.

Note: You can obtain the IP address and computer name of a computer by opening a command prompt (DOS window) and typing IPCONFIG /ALL. This should work for any Windows version. The IPCONFIG /ALL display will provide a wealth of useful information for debugging your network connection.

Check your Services are Started on all PCs:

• Computer Browser
• DHCP Client
• DNS Client
• Network Connections
• Network Location Awareness
• Remote Procedure Call (RPC)
• Server
• TCP/IP Netbios helper
• Workstation

Note: You can check the services in Control Panel, Administrative Tools, Services.

All of these services should be started, and their startup type should be automatic.

All computers should be in the same workgroup for computer browsing to function properly. File & Print Sharing has to be enabled on any computer you wish to share files or printers from. You also need to actually share the resource in question from My Computer, right click on the drive/printer/folder, and select sharing.

If you encounter difficulties accessing computers that are visible in Network Neighborhood, make sure the computer being accessed has an account with the same name/password as the system connecting to it uses to login.

While the default NetBIOS setting is correct for normal network configurations, it's possible for it to be altered, and it costs nothing to make sure it's correct. NETBIOS over TCP/IP must be enabled for normal network browsing.

- Windows firewall is off and no other firewalls are installed to the computer.

- I can ping the IP address, but not the computer name.

- All the services you said to check are started and automatic.

- All computers are in the same workgroup.

- File & Print Sharing is enabled on all computers.

- I have my D: drive shared from this computer. None of the others can see it. Other various folders on the other computers are shared and they can all see each other's shared folders, but I cannot.

- The computers have to have the same username and password? They didn't before the reformat of this computer and we never had an issue and the computers that can still see each other don't either.

- As I said, NetBIOS over TCP/IP is enabled right now, though IPCONFIG /all says it's not.

I don't see the ipconfig readout, please re-post. Also, make sure you're sharing at least one folder on your "server" computer, and please confirm that by "server" you mean Internet Connection Sharing gateway.

I apologize. I must have forgot to paste it.

-- There is a folder shared. In fact, the entire D: drive is shared as well.

-- I'm not so sure this is the server anymore. It used to be, but I'm not 100% sure now. I'll ask my boss when he gets in.

You need to enable NetBIOS over TCP/IP.


Select Start > Settings > Network Connections.

• Double-click the Connection icon of the connection you wish to modify to open the Local Area Connection Status window.
• Click the Properties button to open the Local Area Connection Properties window.
• Click to highlight Internet Protocol (TCP/IP).
• Click the Properties button to open the Internet Protocol (TCP/IP) Properties window.
• TCP/IP Properties window, IP Address tab
• Select Obtain an IP address automatically.
• Select Obtain DNS server address automatically.
• Click OK to return to the Local Area Connection Properties window.
• Click OK to return to the Network Connections window.

[ckile]

They are set to Obtain automatically now and NetBIOS over TCP/IP is still enabled, but IPCONFIG /all still says it's disabled.

It's also worth noting, I don't think NetBIOS over TCP/IP was enabled when everything was working and we had all of the computers set as static IPs.

[JohnWill]

Unless you're in an unusual network configuration, try enabling DHCP as well.

Select Start > Settings > Network Connections.

• Double-click the Connection icon of the connection you wish to modify to open the Local Area Connection Status window.
• Click the Properties button to open the Local Area Connection Properties window.
• Click to highlight Internet Protocol (TCP/IP).
• Click the Properties button to open the Internet Protocol (TCP/IP) Properties window.
• TCP/IP Properties window, IP Address tab
• Select Obtain an IP address automatically.
• Select Obtain DNS server address automatically.
• Click OK to return to the Local Area Connection Properties window.
• Click OK to return to the Network Connections window.

Finally, let's do the stack repair.

TCP/IP stack repair options for use with Windows XP with SP2.

Start, ]R[/B]un, CMD to open a command prompt:

In the command prompt window that opens, type type the following commands:

Note: Type only the text in bold for the following commands.

Reset TCP/IP stack to installation defaults, type: netsh int ip reset reset.log

Reset WINSOCK entries to installation defaults, type: netsh winsock reset catalog

Reboot the machine.

[ckile]

That worked! I can see the other computers now. Thank you so much.

[ckile]

OK, now I can see them, but they still can't see me. Should I go through the same steps that I went through on this computer on the others?

[JohnWill]

That wouldn't hurt, and it may help. After that, if you are still having issues, I'd like to see this for each of the computers.

Hold the Windows key and press R, then type CMD to open a command prompt:

In the command prompt window that opens, type type the following commands, one at a time, followed by the Enter key:

NBTSTAT -n

IPCONFIG /ALL

Right click in the command window and choose Select All, then hit Enter.
