   | Junior Member with 6 posts. | | Join Date: Jul 2009 Experience: Advanced | | Solved: Advanced Networking Problem (WinXP) Hi all, first post. I'm a techie and a programmer, but I can't figure this one out. I have a desktop and a laptop:
Desktop: Windows XP SP2 32-bit
Laptop: Windows Vista SP1 32-bit
Several months ago I put both of them in "stealth" mode so that they were essentially invisible on the network. This involved things like disabling unnecessary services, removing the File/Printer Sharing protocol from the network connections, etc. (I should have written down each and every change so that I could reverse them later on.)
Well, now I want to share them again. I added the File/Printer sharing protocol back, allowed it as an exception in the Firewall on both computers, and re-enabled all of the appropriate networking services. Everything is 99.9% working again -- - Pinging by IP address - OK
- Pinging by computer name - OK (name resolves to the correct IP address)
- Direct access in Explorer via \\computername - OK (shows the shares on computername)
- net view computername - OK (lists the shares on computername)
The only thing which is not working is that the XP computer refuses to show itself -- even from the XP computer -- when browsing the workgroup. (Both have the same workgroup name, simply "WORKGROUP".) The Vista laptop appears on both, and its shares can be browsed by double-clicking it. But something is preventing the XP computer from appearing alongside the Vista computer when browsing the workgroup. (Using "net view" from a command prompt also shows only the Vista computer.)
I have spent hours searching, but most pages offer the typical advice about enabling the Computer Browser, Server, NLA and similar services. These are already enabled (and started) and are not the problem. I have a nagging feeling that I changed some obscure registry setting, but I can confirm that it is NOT the "Hidden" DWORD in HKLM\SYSTEM\CurrentControlSet\Services\Lanmanserver (I have no "Hidden" value there).
Does anyone have any ideas besides reinstalling? I know it's picky to want the computer to show up in the workgroup or "net view" list when I can just as easily type in \\computername to access its shares, but I'm stubborn like that.
Thanks in advance! |  | Senior Member with 311 posts. | | Join Date: Jul 2009 Experience: Einstein | | | | | | Junior Member with 6 posts. | | Join Date: Jul 2009 Experience: Advanced | | I may install that patch later but that's not going to fix it. Everything worked fine with no patches before I did whatever I did.
The core problem is that the XP computer cannot see itself, therefore neither can any other computer on the network. |  | Moderator with 96,694 posts. | | Join Date: Oct 2002 Location: South Eastern PA, USA Experience: Advanced age & experience | | That "patch just enables the eye candy Vista network map, it has nothing to do with file/print sharing on the network.
Let's see this for the XP computer.
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:
Note that there is a space before the -n or the /ALL, but there is NOT a space after the - or / in the following commands.
NBTSTAT -n
IPCONFIG /ALL
Right click in the command window and choose Select All, then hit Enter to copy the contents to the clipboard.
Paste the results in a message here.
If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

In addition, check the services.
Check your Services are Started on all PCs: - COM+ Event System (for WZC issues)
- Computer Browser
- DHCP Client
- DNS Client
- Network Connections
- Network Location Awareness
- Remote Procedure Call (RPC)
- Server
- TCP/IP Netbios helper
- Wireless Zero Configuration (XP wireless configurations only)
- WLAN AutoConfig (Vista wireless configurations only)
- 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 (or perhaps manual).
If a service is not running, open it's properties and check the dependencies. Check each of the dependencies and see which one is preventing the service from running. Checking the event log is also a good idea here, there may be clues to what is failing.

On the XP computer (Desktop), all of the services you listed are started and have a startup type of Automatic, with the exception of the Wireless Zero Configuration because it is a wired connection.
On the Vista computer (Laptop), all of the services including the WLAN AutoConfig are started and Automatic.
The Event Log is a good idea. Do any of the following items sound problematic? -- - Type Warning from Server: The server could not bind to the transport \Device\NetBT_Tcpip_{FA6028C4-22C9-4FD9-8569-0E08F1BFB598}.
- Type Error from Srv: The server's call to a system service failed unexpectedly.
- Type Information from Browser: The browser has forced an election on network \Device\NetBT_Tcpip_{FA6028C4-22C9-4FD9-8569-0E08F1BFB598} because a master browser was stopped.

#10 | You will notice that both computers have the line:
..__MSBROWSE__.<01>
This indicates that both think they're the master browser. This is usually because a firewall on at least one of them is blocking the access.
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: - COM+ Event System (for WZC issues)
- Computer Browser
- DHCP Client
- DNS Client
- Network Connections
- Network Location Awareness
- Remote Procedure Call (RPC)
- Server
- TCP/IP Netbios helper
- Wireless Zero Configuration (XP wireless configurations)
- WLAN AutoConfig (Vista wireless configurations)
- 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.
If a service is not running, open it's properties and check the dependencies. Check each of the dependencies and see which one is preventing the service from running. Checking the event log is also a good idea here, there may be clues to what is failing.
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 Places ( Network and Sharing Center in Vista), make sure the computer being accessed has an account with the same name/password as the system connecting to it uses to login. NOTE: Vista's default is to require a password on the account to enable file/print sharing.
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. You can open a command prompt as described above and type the following command: nbtstat -n. This will display the status of NetBIOS or indicate it's not configured.

#11 | Thanks for all the help John, I ended up figuring it out. At some point I had run the following command: Code: net config server /hidden:yes
To fix it I had to reverse that with the opposite command, Code: net config server /hidden:no
Then disable and re-enable the connection. | | | Moderator with 96,694 posts. | | Join Date: Oct 2002 Location: South Eastern PA, USA Experience: Advanced age & experience |
