Hi there,

I have two domain controlers (DC1 & DC2) in my Virtualize network and for some reason DC2 and nother server (SVR1) are not not authenitcating with DC1. I have the follow messages "there are currently no logon servers available to service the logon request"

the DNS Server is on DC1 which has installed AD SD 2K8. Please see the IP details of DC1

The server 192.168.0.106 is DC2 which also has installed AD DS 2K8.

Has anyone any ideas? What basic troubleshooting should I follow?


It is really appreciate it
