vmware tools upgrade/install change dns settings.

Hey, i have a question.

please forgive me if i am posting in the wrong place.

can an install of vmware tools install or an upgrade change core files and change the DNS settings of the OS? \

i have installed vmware tools and noticed my DNS settings changed.

can it be that vmware tools install  change several system configuration files silently?

i have noticed it changed (maybe) /etc/resolv.conf file

i have tracked down the tools deplot pkg log and saw this:

so, can vmware tools change core files without administrative permissions?

am i missing something here?

please let me know.

Looks strange. vmware tools should not change any thing in the VM.  Can you tell which build your are using and the tools version?

I have a similar problem with windows 2008, when the tools are updated clears its DNS record

Out of curiosity, are are you using the "Flexible" network adapter inside this VM? The flex adapter identifies itself and functions as one of 2 NIC types (Vlance or VMXNET), depending on which driver initializes it. I can't think of another scenario that would require a VMware tools upgrade to mess with the network configuration files.

In either case, if this broke the configuration, it sounds like a bug. You may want to report that with VMware and see what they have to say.
