Ive got a server core domain controller and a server 08 R2 installation both are only 48 hours old however the media server (vanilla server 08 r2 sp1) has started to lockup every reboot.

When this happens the network icon is constantly updating (aero busy icon) and the hyperv console is blank (when i try to connect to the local server) i get RPC call failed after a long delay.

The only way to resolve this temporally is to disable the NIC and virtual network in the device manager, reboot and enable the devices again upon which everything starts to work again.

DCDiag gives the following

C:\Users\Administrator>dcdiag /q
         There are warning or error events within the last 24 hours after the
         SYSVOL has been shared.  Failing SYSVOL replication problems may cause
         Group Policy problems.

The only other symptom i have is a frequent inability to use the FQDN on remote desktop which suggests DNS issues.

set it to allow dynamic updates within DNS, preferably AD integrated. Restart the netlogon service, run ipconfig /registerdns, the run netdiag /fix. Create this zone only on one DC and point both DCs to it for DNS. Within about fifteen minutes or so it should replicate to both DCs and this error gone

Tried all of the above and rebooted with the same net stall , Just to restate in-case ive made a stupid mistake (this is the first domain ive setup).

i used these commands on the vanilla server core install to setup the new domain

Netdom renamecomputer %computername$% DomainMaster
reboot
netsh int ip set address "Local Area Connection" static 192.168.0.4 255.255.255.0 192.168.0.254
Install DNS Role
start /w ocsetup DNS-Server-Core-Role
dcpromo /unattend:c:\unattend.txt

On the server thats hosting the domain controller (the only physical one) i have a dual port nic

1) 192.168.0.1/255.255.255.0/192.168.0.254 (Default gateway) 192.168.0.4 (DNS) 192.168.0.254 (alternative DNS)

2) 192.168.0.2/255.255.255.0/192.168.0.254 (Default gateway) 192.168.0.4 (DNS) 192.168.0.254 (alternative DNS)

Im using the domain account ServerAdministrator@mydomain.com (which might be the problem as the domain controller hasn't even started when i reboot now that i think about it) and when i login hyperv cant even start.

This topic is now closed to further replies.
