Question: ----------------------------------------------
hello, 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_MACHINE\SYSTEM\CurrentControlSet\Servic es\Browser\Parameters\IsDomainMaster 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 \Device\NetBT_Tcpip_{ED0EF83B-C300-450C-9DE1-
83F51F365392}
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
\\UTT-FS0
\\UTT-DC1
\\UTT-FS04
There are 148 servers in domain UTT on transport \Device\NetBT_Tcpip_{ED0EF8
3B-C300-450C-9DE1-83F51F365392}
There are 1 domains in domain UTT on transport \Device\NetBT_Tcpip_{ED0EF83B
-C300-450C-9DE1-83F51F365392}
-------------------------------------------------------------------------------------------------------
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 \Device\NetBT_Tcpip_{ED0EF83B-C300-450C-
9DE1-83F51F365392}
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.
Marcin.
Answer 1: ----------------------------------------------
hi there,
computer browser / populating the computers in network neighborhood should be done automatically , please do not tweak any registry such as changing isdomainmaster .
what i suspect is that there is additional server that wants to participate in the election .
can you switch off the computer browser service and check
a) if you get any error related to computer browser / mrxsmb.
b) if there is a functionality change.
Few Points
a) if you have multiple subnets participating in elections , make sure routers are not forwarding UDP broadcasts
b) try disabling and enablign the NIC
c) make sure you are not running multihomed DC
I would like you to go through the link which is a troubleshooting guide for computer browser relative errors.
