Sometime you setup windows server 2008 to vmware using LAN or wifi, you chose Bridge mode to share internet connections between host and virtual machine may be cause of issues with internet connection at virtual machine. They can not connect to the internet or appear a message likes "conflict IP address"

You may see the following issues:

Next run this command:

C:\Users\lyngtinh>netsh interface ipv4 set interface 11 dadtransmits=0 store=persistent

    1. Thanks Lyn! This worked for me.
      Doing your commands, then stop the DHCP client service (not disabled)
      disabled and reenabled the network adapter and I got internet access :)
      John, if you disable the DHCP client, you need to enter a static IP on your network adapter.

  12. Cleyton, type the part of the command that says 'netsh' onwards, for example just actually type 'netsh interface ipv4 set interface 11 dadtransmits=0 store=persistent' and press .

    'C:\Users\Lyngtinh>' is the bit of the command prompt that is presented to you to type from, your's may say 'C:\Users\Cleyton>', for example...

  13. Thanks for this article, problem solved.

    John, your router connects to the internet and holds the public IP (w.x.y.z) and an internal IP (192.168.1.1) Your server has a static internal IP outside of the DHCP scope (192.168.1.2) and uses default gateway of 192.168.1.1 to connect to the internet.

  18. Do we have a way to fix this problem in Linux (CentOS)? BTW, thanks for the very helpful tip. I was able fix my windows machine. I still have to look for the Linux one. I wish I could have access to the default-gateway router to clear ip arp cache. However, it is not the case

  19. Wow, I've been searching for 3 days. MS's site SUCKS! Thank you for posting this. I've got server 2012, some intel 10gig x520 da cards and setting up IScsi and have been racking my brain/online trying to figure it out. Every reboot take 10 minutes due to 520 gigs of ram have to load. This worked the first try! Thanks again!
