Network Connection Lost After Installing Parallels

Hello,

In Mac OS, it can automatically detect NAS connected to router. After installing Parallels, Mac OS no longer detect it anymore. The network window is now empty.

No network is detected in Parallels either.

any idea how to fix it this?

Thanks

 

Please put here
ifconfig -a from Terminal in Mac OS

ipconfig /all from Windows

 

from Terminal in Mac OS

Thank you,
What build you are using?
Also, is there firewall on Mac OS?
Do you have another Mac in Network and is NAS shown in Network node for that Mac?

 

i am using Mac OS X ver 10.5.2

no firewall on the OS

this is the only one Mac on the network.

i have one PC and one Mac. it works fine on the PC.

 

btw, both Mac & PC work fine b4 installing Parallels.

 

What Parallels Desktop build you are using?

 

Did you reboot the Mac after Parallels was installed?

 

it's Parallels Desktop 3.0 for Mac

yes, i did reboot my Mac after installing Parallels

 

What Parallels Desktop build you are using?

Parallels Desktop -> About Parallels Desktop

 

Build 5608 (10 June 2008)

 

One more question, Are you able to access Internet from Mac OS and Windows?

 

yes, i can access internet from both Mac OS and Windows.

initally right after installing Parallels, Mac OS reports IP address clash with Windows. After re-configuring windows to use a different IP address, both systems work fine now.

 

I suppose it is somehow related to problem,
Try following:
1. Regenerate MAC address for VM from Configuration Editor- Network Adapter 1
2. Switch VM networking to Bridged Ethernet
