I have found that kudzu does this if it detects changes in the MAC addresses of your NICs. Did you clone/copy your virtual machine and did VMware regenerate MAC addresses for your virtual NICs? Cheers, Michael _______________________________________________ I had this as well. I found that if you configured you ifcfg interface script with the MAC address included and uncommented, kudzu no longer manipulated the file.
