Snow Leopard - Unable to use network adapter

After upgrade:
Unable to use the network adapter 1.

Make sure that the network adapter 0 is available and enabled on your Mac.

I have uninstalled and reinstalled a number of times. I have recreated my guest OS's. Same issue regardless of Win OS (Xp and Vista).

Any suggestions?

I have the same issue

Has a solution to this issue been found?

 

The solution that I'm aware of - is to run Cleanup Utility from http://kb.parallels.com/en/6317

 

Had the same issue running Leopard 10.5.8 and parallels 4.0.3846,
I ran the Cleanup Kernel Extensions script (?) and now everything is back to normal.
thanks
