Netlogon Reports:Cannot query DNS

Hi all,

i've got a problem with an Windows 2003 Server. Sometimes the cluster services did not start automatically while an logon error occurs. After a interactive logon the server can be started manually and it's working fine.

Sometime i receive an error from the netlogon service: "Error 5719 There are currently no logon server available to service the logon request "
So i enabled the debugging option of the netlogon service.
The NETLOGON Debuging log reports the following lines:

....

in my opinion there is maybe a problem with the dns client service or the network interface.
So here is my question: Is there any posibility to generate a debug log from the dns client service?

Is your DNS local or at your ISP?

One affected server or several?

Wired/wireless network or some sort of VPN connection?

2003 clustering services can be
- cluster service
- load balancing
- both

If you are running 'cluster service' with some number of clustered servers, then your original problem statement is leavning me a little confused. Could you explain more about what is happening.

 

The DNS environment is basded on a BIND infrastrucutre. But i don't think the problem is at the dns server, because we have many, many server running without this problem

There is only one Windows 2003 Cluster Server (MS Cluster Service) affected.
The Server has 2 x 100MBit/s interfaces and one 1GB/s interface. But the Microsoft Client und Server are only bind to one 100MBit/s interface. (The 1GB interface is connected to the Backup infrastructure, and the second 100MBit/s interface is connected to a managment network)
