            Event String:
            During the past 4.22 hours there have been 4 connections to this Domain Controller from client machines whos
e 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 si
tes, 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 '%S
ystemRoot%\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 informati
on, please search for lines which contain text 'NO_CLIENT_SITE:'. The first word after this string is the client name an
d 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 2000000
0 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.
