Hi everyone,

I am having serious problems with one of the exchange servers in our
local forest. information store terminates unexpectedly. These are the
errors I see from the event viewer:

System errors:
-The browser service has failed to retrieve the backup list too many
times on transport \Device\NetBT_Tcpip_{8B480F1A-09F0-4D1F-8A63-
C23E28CED49F}. The backup browser is stopping.
-The browser service was unable to retrieve a list of servers from the
browser master \\SERVER1 on the network \Device
\NetBT_Tcpip_{8B480F1A-09F0-4D1F-8A63-C23E28CED49F}
-During the past 4.18 hours there have been 431 connections to this
Domain Controller from client machines whose IP addresses don't map to
any of the existing sites in the enterprise. Those clients, therefore,
have undefined sites and may connect to any Domain Controller
including those that are in far distant locations from the clients. A
client's site is determined by the mapping of its subnet to one of the
existing sites. To move the above clients to one of the sites, please
consider creating subnet object(s) covering the above IP addresses
with mapping to one of the existing sites. The names and IP addresses
of the clients in question have been logged on this computer in the
following log file '%SystemRoot%\debug\netlogon.log' and, potentially,
in the log file '%SystemRoot%\debug\netlogon.bak' created if the
former log becomes full. The log(s) may contain additional unrelated
debugging information. To filter out the needed information, please
search for lines which contain text 'NO_CLIENT_SITE:'. The first word
after this string is the client name and the second word is the client
IP address. The maximum size of the log(s) is controlled by the
following registry DWORD value 'HKEY_LOCAL_MACHINE\SYSTEM
\CurrentControlSet\Services\Netlogon\Parameters\LogFileMaxSize'; the
default is 20000000 bytes. The current maximum size is 20000000
bytes. To set a different maximum size, create the above registry
value and set the desired maximum size in bytes.


After the information store crash, I see some dump files. I could not
find a dump analyzer that will review the store.exe.mdmp and give me
some results. Does anyone know any tool that can do this, please? I
ran debugdiag, winternals crash analyzer, windbg. All were
unsuccessful.

thanks for your help in advance. have a good day,

emre
