I have a DNS domain and host it on my own server. My desktop PC (Windows XP) is configured to have mydomain.tld as its primary DNS suffix. Now, when the system tries to resolve any domain - stackoverflow.com, for example - it tries with the suffix added first, even if the name has periods in it. In other words, it tries stackoverflow.com.mydomain.tld. before stackoverflow.com..

  1. Is this valid according to DNS standards and common sense?
  2. Is there anything I can do to prevent it, other than removing the prefix completely? (I still want it to be appended to single-component hostnames. Currently I have two prefixes . and mydomain.tld. configured, but it isn't very fast when resolving foohost.)
