Hi,

One of the DC has a ip address as 169.254.x.x which I think is causing issue with my dfsr. 

How do i remove this connection and make sure my dns doesnt have this address.

This server is DNS, DHCP

Check for non-present devices.

COMMAND LINE | To show hidden devices in Device Manager

From an admin cmd prompt:

Type set devmgr_show_nonpresent_devices=1 and hit ENTER.
Type cd\windows\system32 and hit ENTER.
Type start devmgmt.msc and hit ENTER.
When the device manager opens, click the View menu.
Click Show Hidden Devices.

Remove any non present NICs

Does the computer have a second NIC?

Run ipconfig /all from a cmd prompt.

If the computer is getting two IP addresses it may be registering  them both in DNS.

Try disabling the unused NIC, manually remove the 169.254 record from DNS and from the local machine open a cmd prompt as admin and run ipconfig /flushdns && ipconfig /registerdns.

Hi,

169.254.x.x ip range will be visible when you have a network card with DHCP enabled and it is unable to locate the DHCP server. It is called Automatic private ip addressing.

Thanks

Hi,

If the DHCP server cannot be found, Windows TCP/IP uses Automatic Private IP Addressing (APIPA). 

And you should assign a static IP address to your DC.

Hi,

No Sceond network card as you can see from network connection but if i do IPconfig, its listing 3 cards.

Even when I check the scvmm I can only see 1 card.

This is having effects on resolve the name correctly for this server.

When I chechk the name server this dc show as unresolve address.

This done the trick. I cant see 169 address anymore. however after uninstalling hidden network card i did loose the ip address. I have to re-enter all of the details.

Thank you for your help.
