Hey friends,
I am trying to troubleshoot the cause of one of my domain controllers (vmware virtual server servers) shutting down last night and while looking through the System log in the event viewer I spotted something that I am trying to determine how concerned I should be about it. The first sentence concerns me the most because I am not sure if it's an issue or not. So at that location we do have users from other office go there and log in so they should be hitting that domain controller any way.
Also, in Computer Management, Under shared folders I looked at the "sessions" folder and can see a mix of computer authenticated that are local to that site and also some from other other sites, I am thinking those are visitors to the office?
Below is from the System log in the even viewer.
During the past 4.21 hours there have been 60 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.
