Could not see all the computer in the same domain network

    Question

  • I'm using Windows Server 2003 for my AD. Previously, I'm able to see all my network computers in my domain network (about 200+ computers including servers). Now, only able to see about 10 units computer in the domain network only. May I know is there configuration problem in my AD server?

    I tried to use command prompt to browse the computer list in my network too but error occured.

    "A remote API error occurred. More help is available by typing NET HELPMSG 2127."

    I did Bing for the error message 2127 but I couldn't understand the actual steps I need to perform.

    "Action: Contact your network administrator. Your administrator should make sure that the server is configured with enough resources. Specifically, the NUMBIGBUF entry in the server's configuration file may need to be increased."

  • Hi,

    According to your description, it seems the issue is related to the Computer Browser Service.

    Computer Browser Service can be responsible for maintaining a browser list which is a list of computers in the domain. With the help of the browsing service, every system does not need to hold a computer list for itself. Instead, the Master Browsers collect the computer list for the whole network, and provide the list to other systems.

    The computer browser service is a legacy technology. Often, the computer list would not be complete. Creating a WINS server in the environment and configuring all machines to use the WINS server would do some help.

    Even if we do not use the Computer Browser service, it does not cause negative impact when you try to access the shares on the computers. You can directly access the computer you want in the domain with the UNC format by entering \\computername. This does not depend on the Computer Browser Service.

  • Hello,

    do you use multiple subnets? Then WINS is the way to be sure to see all.

    Assure that NetBios over TCP/IP is enabled on the machines NICs and that the computer browser service is started also.

    If you think your AD is not working correct, which normally has not an influence on the network neighborhood view, check with the support tools and if you think we should review please upload them:

    ipconfig /all >c:\ipconfig.log [all DCs]
    dcdiag /v /c /d /e /s:dcname >c:\dcdiag.log
    repadmin /showrepl dc* /verbose /all /intersite >c:\repl.log  ["dc* is a place holder for the starting name of the DCs if they all begin the same (if more then one DC exists)]
    dnslint /ad /s "DCipaddress" (http://support.microsoft.com/kb/321045)
    ADREPLSTATUS: http://www.microsoft.com/en-us/download/details.aspx?id=30005 can also be exported to file.

    As the output will become large, DON'T post them into the thread, please use Windows Sky Drive(with open access!) https://skydrive.live.com and add the link from it here. Also the /e in dcdiag scans the complete forest, so better run it on COB.

  • Dear M. Weber,

    I try to get u the file.

    I just enable NETBIOS but I didn't restart my server.

    After NETBIOS enabled, I can view all computers.
    After awhile, I couldn't see those computers in the network again.

    FYI, I did change NIC before.
