Parallels network connections have self-assigned IP addresses

Periodically, the Parallels network connections decide that they want to have self-assigned IP addresses. The only way I have been able to resolve this is to reinstall Parallels, which is simple, but still I don't believe I should have to do this. I've tried refreshing the network connections in System Preferences, but that doesn't work. Is there another way to reset the Parallels network adapters w/o reinstalling Parallels?

 

Restarting the Mac fixes the problem for me.

 

Some situations can lead to such behavior
- You manually limited DHCP scope - in Parallels Desktop -Preferences -Network increase scope
- You have connected Wireless Modem, which either shutdown, or affects Parallels NAT stability - unplug wireless modem
- Incorrect permissions or corrupted file /Library/Parallels/.parallels_dhcp_leases
You need to get root
to perform operations bellow sudo is not working
echo > /Library/Parallels/.parallels_dhcp_leases
killall -HUP pvsnatd

 

Thank you John! I did this yesterday and it solved the problem! R

 

John, I have the same problem. Everything was working fine, then the last time I started up, the NAT device gets a self assigned address, can't get to the DHCP. The Parallels Guest is fine.

So can you put your instructions into English? I can run a terminal line, but how do I get to root?

Thanks

Russ

 

open Terminal
sudo passwd root
enter twice root password

 

Please don't do this. There's a reason why OS X ships without root enabled.

Get a root shell by running sudo -s. Then run the commands.

The commands in sequence would be:

% sudo -s
% echo > /Library/Parallels/.parallels_dhcp_leases
% killall -HUP pvsnatd
