Troubleshooting nslookup Problems

The last thing you want is to have problems with your troubleshooting tool. Unfortunately, some types of failures render the troubleshooting tool mostly useless. Other types of nslookup failures are, at best, confusing because they don’t give you any direct information to work with.
