My office Workstation name is "Workgroup". Here 8 computers connected in same workstation. Sometime I check how many computer connected. My server os is "windows 2000 advance Server" and the other computer's OS are WINXP home Edition and winXP Professional Edition. The Problem is- When I want to see how many computer connected, but there are 2 of 8 computer name didn't show. one's OS is WINXP Home Edition and Other is WinXP Professional Edition. but from these 2 computers I can see the other computers and can access them. these 2 are same workstation and unique ip. so what can i do now.

Thanks. We'll let you know when a new response is added.

Is the firewall turned on on the workstations that you can not see?

    Hi, Not sure if you are using a DNS server in this configuration but let's start with the basics. Can all the computers ping each other? If so, make sure you have "File and Print Sharing" configured on all of them. Also make sure all computers are configured on the same workgroup. What also happens with Windows is that the network TCP/IP settings become corrupt when playing extensively with them. To correct the problem, change your network TCP setting to DHCP, apply it and then change it back to Static or visa versa. This will rewrite the configuration file holding these settings.

    As another replier asked can all computers ping each other? Check that the microsoft or other firewall or off. (Presuming you are behind a server running DHCP and firewall. Check the file and print sharing on all computers. If this doesn't work keep a default folder shared on each machine.

    Normally workgroup browsing is possible through Netbios over TCP/IP broadcasts. So check that netbios haven't been disabled. Another thing to check is wether the "server service" is running on the 2 problem computers (can you create shares etc). If server services isn't running then the computer will not broadcast the Computername20 attribute and will not be listed on the browselist supplied by the master browser.

    You said that the workstation is named "Workgroup". If you meant the computer name is "Workgroup" this would be an unusual (and dangerous) name for a computer. Did you mean that the workgroup name of your computer is "Workgroup"? Computer names and workgroup/domain names (as well as usernames) are all NetBIOS names and must be unique within the NetBIOS name space. Check that the computer name is not the same as your workgroup/domain name and not the same as any other computer name. You said that your server is Windows 2000 Server. From this I assume that you have created an Active Directory (AD) domain (unless you have installed the server as a stand alone computer or as a member server and not as a domain controller (DC)). I hope that this domain has a name other than "Workgroup". Do you have both a domain and a workgroup? If so, the list of computers in the workgroup is maintained by the workgroup computers (shared among the computers) and the list of computers in the domain is maintained by the domain (by a DC). When you are checking how many computers are connected, are you using Network Neighborhood (My Network Places)? The list of domains/workgroups and computers within those domains/workgroups is maintained by the Computer Browser Service. That service elects a Browse Master (and some number of backup browsers). There is (or needs to be) a master browser in each workgroup or domain. If you have both a domain and a workgroup, you need two browse masters (one for the domain and one for the workgroup). In a domain, a domain controller (DC) will be the master browser. In a workgroup, the computers will elect some computer to be the master browser. Network Neighborhood only lists "servers". In this context a "server" is any computer that is capable of sharing folders or printers. It does not need to be running a server operating system; it can be a workstation (such as Windows XP Professional) but it must have File and Printer Sharing enabled (and not firewalled). (It is not necessary that the computers are actually sharing something, only that the Server Service is running and accessible.) Others have mentioned checking that the workstations are not preventing connection to file and printer sharing via a desktop firewall. You mentioned that one computer is Windows XP Home. WinXP Home is not capable of joining a domain. So if you really have a domain, that workstation OS must be upgraded to WinXP Pro. If computers in your workgroup are turned on and off frequently, you could lose the browse master and it can take up to an hour for the network neighborhood list to be up-to-date (before another computer is elected to be the master browser and collects all the information about the domains/workgroups and the computers within those domains/workgroups). (This is a well known effect of the way the computer browser service works.) Some computers do not do a good job of maintaining the list of computers in the workgroup. If you find that you have such computers, it is possible to force them to not be elected to be the browse master. As others have mentioned, the underlying nework must be working correctly before the Computer Browser service can work. So checking that you have network connectivity (such as with a PING) is the first thing to do. Once the network connectivity is confirmed, then you can check that you have NetBIOS connectivity to the workstations. This can be done from a command prompt by typing the command: NET VIEW computer where "computer" is the computer name (NetBIOS name) of the computer to which you want to verify connectivity. If you have such connectivity and the names are just not showing up in Network Neighborhood, the problem is the browse masters. Please let us know more about your workgroup/domain configuration so that we can help you appropriately.

    The command to check NetBIOS connectivity is NET VIEW computer (I mistyped the command earlier)

    (There is something about the posting that is altering the command; it is turning two backslashes into a single backslash.) The command to check NetBIOS connectivity is: NET VIEW ^backslash^^backslash^^computer^ where ^backslash^ is a "" character (without the quotes) and ^computer^ is the computer name (NetBIOS name) of the computer to which you want to check the NetBIOS connectivity.

    NBTstat is probably another helpful command here. There are several optional on end. It will show status of NBT traffic and stations (other comments have noted this)
