Change IP Address of EBS Conflict with router

So I am one of the handfull of people that purchased EBS, no laughing. Normally it has been a good product. Recently though I had the need to move our management server to another location which involved another subnet.

One of the things you really want to remember is that you must change it's ip address first and then move it. The reason is because you are strongly recommended by microsoft to use their "Change IP Address Settings" wizard. This wizard checks connectivity with the other two servers and makes changes to them.This is fine but I ran into a little problem. Something I am not new. to

Sadly the setup of EBS was a royal pain. after it was setup it was fine but I have not been in any way impressed with their wizards, setup or other. Maybe for some they worked but I think it's just that updates broke them and the EBS team had given up the ghost, even before the announcement was made.

Anyways Back to the story. After firing up the wizard and having it do it's check it provides you a box to change the IP Address, Subnet Mask, and the Gateway. After changing the Gateway and IP address. It came up with the error you see in the picture above.The selected IP address is already in use by another system with physical address XX-XX-XX-XX-XX-XX. (In the picture above I changed the Hardware address.)

So I double checked to ensure the address I gave it wasn't already used. I then moved to an IP above. Got the same message with the same physical address. Tried 4 other IPs all same physical address. So I checked the arp table. That physical address was tied to my router. A tad odd. Any address from the other subnet I put in their gave me that error. I have never had any other product point to my router like this. So after doing no searching I tried my own solution that worked.

Right after you enter the IP address but right before you click on the "change" button it is going to do a check to see if that IP address is in use, which in my case was broken and stopped me from working. So right before clicking "Change" then unplug the server from the network and as soon as the "Progress of IP address change"(Next screen) screen comes up then quickly plug it back in. If you don't then you will get errors on this screen, and will have to close the wizard and try again.

After using the unplug method to skip the error check I was able to move the server. Problem was I had to change some of the security server firewall settings. For Example I had to change the IP address of my Mangement computer under these two computer sets:

• Remote Management Computer
• DNS Servers

Also had to update a few other custom policies, after that though it straightened all of that out. You will also need to upgrade some group policies. Follow the instructions at this technet link: http://technet.microsoft.com/en-us/library/dd996618(WS.10).aspx
