Windows Server 2012

Hi,

I have a new 2012 server and 4 new Windows 8 Pro workstations in a new domain. Every day since we went live the network drops out locally and on the internet. I have the the following configuration:

Netgear DGN2200 ADSL router plugged into a Netgear Gigabyte switch.
The server and the 4 PC's plug into the switch.

Router: 192.168.5.1
 Internet Port
MAC Address      E0:46:9A:63:85:78
IP Address      149.135.2.241
Network Type      PPPoA
IP Subnet Mask      255.255.255.255
Gateway IP Address      165.228.7.1
Domain Name Server
203.50.2.71
139.130.4.4

2012 Server:
IP: 192.168.5.10
SUB: 255.255.255.0
GW: 192.168.5.1

DNS1: 192.168.5.1
DNS2: 192.168.5.10

I have given all the PC's static IP addresses with the following config: (with different IP's)
 IPv4 Address. . . . . . . . . . . : 192.168.5.32(Preferred)
 Subnet Mask . . . . . . . . . . . : 255.255.255.0
 Default Gateway . . . . . . . . . : 192.168.5.1
 DNS Servers . . . . . . . . . . . : 192.168.5.10
  DNS                                      192.168.5.1
 NetBIOS over Tcpip. . . . . . . . : Enabled

I ran the BPA analyzer on the server and got these results:

When I setup the server I just did the default settings.
Do I need to add stuff to DNS

The server keeps changing from Domain to Public

I have also turned DHCP off on the server.

If I restart the router, switch, server and workstations it comes right.

If I haven't set the server correctly up can anyone give me some pointers

Thanks

You should not use the gateway as a DNS server. it can't do AD integrated DNS.
If you have only one Domain controller it should be the DNS server for the other machines and for itself.
Alan Gunn

Hi!
Happy New year!

The possible source of problems is that the DNS server for the domain controller (DC) and computers should be the one running on the DC.

The config above appears to be using the DNS supplied by the router.

Set all the machines to use the DC as DNS, including the DC.
The DNS server on the DC should already know all teh info the errors are indicating are not available from the Router DNS.


Once this is working, you set up the DNS server on teh DC to forward DNS requests to the router DNS for addresses external to your network.


Cheers!

Hi Phillip,

Can you give me some instructions on how to setup the forwarders in DNS

Thanks

Andrew
Your help has saved me hundreds of hours of internet surfing.

As has been said - the ONLY DNS server listed should be that of the Windows Server  - any other configuration will cause internal name resolution to fail.

to set up forwarders see http://technet.microsoft.com/en-us/library/cc754941.aspx
Philip Elder

Start --> DNSMgmt.msc [CTRL + ENTER}
Click on SERVERNAME
Right click and Properties.
Forwarders tab.
Make sure "Use root hints if no forwarders are available" is checked.
Click EDIT button.
Enter the DNS server IP addresses there.
Click OK and OK.

We do this because the Root Hints cache bug has not been fixed since Server 2008.

Note the IPs are for our own ISP up here.
