I have 2 virtual machines running in 2 different environments, one is a windows xp box running VMware 5.5 and the other is a windows 2008 r2 server running VMware 4.1. like I said it runs in separate blade enclosures. These 2 machines are causing each a drop in each others network connections. When the one is up the other one is down and vice versa, you will get a reply from 1 and then the other 1 stops replying and then after 2 minutes or so the opposite happens.  There is no ip or name conflicts, there is no problem with the hosts it is running on or with the blade enclosures, please assist.

Thank you

Do both the machines have multiple NIC cards? i have seen this happen in scenarios where the VM's had more than one NIC cards.

You probably checked this already but...Are the MAC addresses on the VM's cards the same by any chance?

Then may be that's the cause. Change the MAC address and see if this issue is resolved.

:-) yes, that's why you are having issues.

To change this in VMware ESXi/vSphere:
-  Go to (at least) one virtual machine's "Settings" -> "Hardware" tab
-  Select the network adapter, and edit it.
-  Change the MAC address setting from Manual to Auto, or manually input a MAC address that is different form any other on your network.

The machine must be shut down before the NIC settings can be changed.

I believe that just setting them to Auto is easier, but there may be a legitimate reason why the MAC address is set manually. You may have to investigate...

Regards,

Carlos
