  • exchange errors

    I am migrating to exchange 2003 by just adding a new server, replicating folders, and moving mailboxes, rehoming, etc.

    Found a guide and following it.
    All was going great and today I had some issues with the dc's and dcdiag failed connectivity test. I rebooted them and things went back to good, I also changed the nic properties on them to point to themselves instead of eachother first. they are across vlans. It was working fine though.
    So today I found that dns stopped working almost becaue I couldn't rehome rus which got me digging.

    So why would the dc's do that, no errors, nothing? The failed connectivity test was just that it couldn't resolve it's name in dns but that the guid matched? I lost the event log, someone wiped it out.

    So the only other failures were system logs with some netlogon errors I am getting because of some machines that need to be readded to the domain and then another error
    5807 netlogon
    During the past 4.04 hours there have been 12 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\Servi ces\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.
