what is the best way to deal with a ipconflict in vmware?

NAMEWITHELD12 used Ask the Experts™
I am getting errors in vmware vcenter that there is an IP CONFLICT , what is the best way to track down the conflict the error says who the current owner is but all it gives is a mac address??????

can I use RV tools or some other way to find what the source of the other IP that is in conflict is????? ,

 I am sure one of them is a vMK port as I can see the ip in question , but how to i find the other offending IP address?

Set your network adapters to dynamic and the IP conflicts should not occur.


for the guests ? or for the hosts or both ?

how do you do that?

thanks , I really appreciate the help!!!!!!!!
I would do it for all VM's which should resolve your problem.

Log in on each VM and go into the network properties, select the network adapter that's connected, right click it and select properties, select TCP/ipv4 and click the properties button.

then click Obtain... in the top and bottom sections of the box. this tells that VM to obtain a unique IP from the DHCP server.  I assume you have a server or router running DHCP. Most networks have that in place.

Here is a video that shows the process.

I think I would start by running a report (script), to generate and output the IP Addresses and MAC Addresses of all VMs managed by vCenter Server.

This will give you an idea, if all MAC Addresses are UNIQUE sometimes, you could have a duplicate!
