Server connectivity breaking every morning
Posted on 2010-11-24
Got a strange problem, a network with a single 2008 SBS Server and 5 XP Pro/Win7 Pro client machines seems to be failing every morning when the staff log on. The computers will log on but when they click on the mapped drives explorer hangs for a while then eventually times out. this has been happening for a few days now and a server reboot has normally fixed it but today the server has been rebooted twice and still the same thing happens. Exchange seems to be working and emails are coming in.
Have checked the logs on the server and the following errors stand out:
The winlogon notification subscriber <GPClient> took 123 second(s) to handle the notification event (CreateSession
Process STORE.EXE (PID=2380). Error DNS_ERROR_RCODE_NAME_ERROR (0x8007232b) occurred when DNS was queried for the service location (SRV) resource record used to locate a domain controller for domain exampledomain.local
The query was for the SRV record for _ldap._tcp.dc._msdcs.exampledomain.local
Common causes of this error include the following:
- The DNS SRV records required to locate a domain controller for the domain are not registered in DNS. These records are registered with a DNS server automatically when a domain controller is added to a domain. They are updated by the domain controller at set intervals. This computer is configured to use DNS servers with following IP addresses:
- One or more of the following zones do not include delegation to its child zone:
. (the root zone)
For information about correcting this problem, type in the command line:
Process STORE.EXE (PID=2380). None of the domain controllers in the domain are responding. This event can occur if the domain controllers in local or all domains become unreachable because of network problems. Use the Ping or PathPing command-line tools to test network connectivity to local domain controllers. Run the Dcdiag command line tool to test domain controller health.
Failed to shut down service. The error that occurred was: System.InvalidOperationException: UpdatePendingStatus can only be called during the handling of Start, Stop, Pause and Continue commands.
at System.ServiceProcess.ServiceBase.RequestAdditionalTime(Int32 milliseconds)
Do any of these offer a clue as to what is going wrong?
