Hi All
can anyone help
Thank you
Mark  

         During the past 4.25 hours there have been 503 connections to this D
omain Controller from client machines whose IP addresses don't map to any of the
 existing sites in the enterprise. Those clients, therefore, have undefined site
s and may connect to any Domain Controller including those that are in far dista
nt locations from the clients. A client's site is determined by the mapping of i
ts 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 c
lients 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 cont
ain additional unrelated debugging information. To filter out the needed informa
tion, please search for lines which contain text 'NO_CLIENT_SITE:'. The first wo
rd after this string is the client name and the second word is the client IP add
ress. The maximum size of the log(s) is controlled by the following registry DWO
RD value 'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Paramete
rs\LogFileMaxSize'; the default is 20000000 bytes.  The current maximum size is
20000000 bytes.  To set a different maximum size, create the above registry valu
e and set the desired maximum size in bytes.
         An error event occurred.  EventID: 0x40000004
