    I have a problem which you’ve probably heard a lot of – master browser – I keep getting error – MRxSmb event ID 8003. Before deciding to ask for any ideas I spent day googling and trying to solve it. What I did:
    1. I switched the computer browser service on PC which “belived that it was the master browser” but few minutes after I get the same error but from another PC (random).
    2. HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServic esBrowserParametersIsDomainMaster to TRUE – no joy – still getting the same error.
    3. Restarted DC.
    4. Additional info: there are 3 subnets in our network, WINS server (running on DC), there are many laptops machines (so wireless and Ethernet cards..).

    No joy – I keep getting the same errors in DC log. I used browstat:
    1. browstat.exe status:

    Status for domain UTT on transport DeviceNetBT_Tcpip_{ED0EF83B-C300-450C-9DE1-
    Browsing is active on domain.
    Master browser name is: UTT-DC1
    Master browser is running build 3790
    3 backup servers retrieved from master UTT-DC1
    There are 148 servers in domain UTT on transport DeviceNetBT_Tcpip_{ED0EF8
    There are 1 domains in domain UTT on transport DeviceNetBT_Tcpip_{ED0EF83B

    The backup servers seems to be changing quite often – I don’t know if it should be like that.

    2. What worries me if I use command “browstat status \UTT-DC1” I do not get a response:

    C:>Browstat.exe status \UTT-DC1

    Status for domain \utt-dc1 on transport DeviceNetBT_Tcpip_{ED0EF83B-C300-450C-
    Browsing is NOT active on domain.
    Master name cannot be determined from GetAdapterStatus.

    Any ideas what shall I do? I’ve read that I can use GP to switch off Computer Browser service on all PC. Shall I go for this option? What happens if there is no computer on different subnetwork with Computer Browser running – will I still be able to use all PCs in My Network Places?

    Sorry for such a long post but I wanted to put as many details as possible.

    Thank you for your help.
