Hello All

I have TMG server installed on windows 2008 R2 64x  with 3 network adaptor (Lan,Premiter and External), but for some reason the clients on premiter Network cant get ip addresses from dhcp which located on LAN. i have done 

ipconfig /release

ipconfig /flushdns

ipconfig /renew 

but no success...... also uninstalled premiter network adaptor and reinstall network adaptor still no success.....getting this error.

An error occurred while releasing interface Loopback Pseudo-Interface 1 : The system cannot find the file specified

by the way My Lab is based on Hyper-v

any help would be much greatfull

thanks
