I'm trying to configure a server with virtual machines on Windows Server 2012, after finishing the installation of windows in the VM, I try to configure the IP as static, but a second address is assigned to the VM, which gets two addresses being the configured manually the second.

The configuration looks like this:

  • Connection-specific DNS Suffix:
  • Description: Microsoft Hyper-V Network Adapter
  • Physical Address: 00-15-5D-FE-0C-01
  • DHCP Enabled: No
  • Autoconfiguration IPv4 Address: 169.254.243.109
  • IPv4 Subnet Mask: 255.255.0.0
  • Autoconfiguration IPv4 Address: 192.168.254.30
  • IPv4 Subnet Mask: 255.255.255.0
  • IPv4 Default Gateway: 192.168.254.1
  • IPv4 DNS Server: 192.168.254.1
  • IPv4 WINS Server:
  • NetBIOS over Tcpip Enabled: Yes
  • Link-local IPv6 Address: fe80::3dbd:694d:2c37:f36d%12
  • IPv6 Default Gateway:
  • IPv6 DNS Server:

When should look like this:

  • Connection-specific DNS Suffix:
  • Description: Microsoft Hyper-V Network Adapter
  • Physical Address: 00-15-5D-FE-0C-01
  • DHCP Enabled: No
  • Autoconfiguration IPv4 Address: 192.168.254.30
  • IPv4 Subnet Mask: 255.255.255.0
  • IPv4 Default Gateway: 192.168.254.1
  • IPv4 DNS Server: 192.168.254.1
  • IPv4 WINS Server:
  • NetBIOS over Tcpip Enabled: Yes
  • Link-local IPv6 Address: fe80::3dbd:694d:2c37:f36d%12
  • IPv6 Default Gateway:
  • IPv6 DNS Server:

Any help is welcome

Double check that the IP address you're assigning (192.168.254.30) isn't already in use. Sometimes an IP clash on the network can cause these symptoms. –  Graham Wager Dec 7 '12 at 19:04
    
Is there an actual problem or is this just cosmetic? –  David Schwartz Dec 7 '12 at 23:12
    
It's a real problem. –  Israel Pinheiro Dec 10 '12 at 12:20
    
Graham Wager, thanks for the help, somehow the DHCP server was assigning adresses from a exclusion range, now everything is OK –  Israel Pinheiro Dec 10 '12 at 12:28
