In the past week we've noticed that all our NSLookups are appending the parents domain suffixes for example:
"NSLookup server.domain.net.nz" :- returns
The 202.xx.xx.xx.xx Address actually belongs to nz.net.nz, which is nothing to do with our company.
Now this has just started happening all the IT Admins swear they haven't changed anything and there have been no other known changes. One of our IT Admins has an Active Directory Setup at home and he's also having the same problems. We know we can apply a fix for this automatically via Group Policy and/or manually via TCP/IP (Advanced - DNS) Properties, by changing the "Append these DNS suffixes (in order)":. But the question is why has it started happening all of a sudden and is it possible to change it, without going through Group Policy or TCP/IP Properties.
