Hi,
try it with the -Append param on Export-CSV
http://technet.microsoft.com/en-us/library/hh849932.aspx
I got the correct output, when I put your whole select into one single line. Did you forgot the single backtick on the first line $dev | select ` ?
Are you sure the other nic has an IP assigned and is enabled in the GuestOS? If it's not, it won't even run into the third foreach.
Regards
Emanuel
