    Hi i am after some advice

    i need to be able to find out what application/service is sending out net bios broadcasts on a network segment the requests are for machines that no longer are on the network but something is trying to obtain there ip address as they are not in dns any more i am assuming this is why they are resorting to netbios broadcasts i need to some how isolate what application or service is trying to find out. but have no idea how to go about it any help or advice would be great


    thanks in advance

    Do you know what the devices were that are no longer a part of the network?

    HAve the workstations been deleted from AD users and computers as well as DNS? You might want to purge the DNS cache on the workstations as well.

    Don't be so sure, people are by nature lazy. You are not sure if you run Active Directory?

    after doing some more research i have found that the packets have the 20 identifier after the host name am i right in assuming this is file server service and if so why are other workstations looking for this workstation and more to the point how can i stop them broadcasting to look for this workstation. Also i was thinking maybe there was a shared printer on this worksation but as it is gone now i have no way of knowing
