I'm having problems with ipconfig /release6 and ipconfig /renew6not working properly. They both generate these errors:ipconfig /renew6Windows IP Configuration An error occurred while renewing interface LAN : The system cannot find the file specified. An error occurred while renewing interface Loopback Pseudo-Interface 1 : The system cannot find the file specified.Is anyone else seeing this problem and is there any fix? -Mikael

Hello,I have the same problem on one of my computers:It has no IPv6 address on its LAN card. (Contrary to all my other computers)And when I try ipconfig /renew6, it displays:An error occurred while renewing interface Loopback Pseudo-Interface 1 : The system cannot find the file specified.Did you eventually find a fixfor your case?Jean-Franois

Instead of attempting to use the name of the adapter, try to use the index, e.g.: ipconfig /release6 8 Where 8 is the index shown by the command: netsh interface ipv6 show interfacehttp://sharepoint.nauplius.net
