You got it! It's those darn application programmers! :-) Realistically it would make sense for browsers to try alternate DNS info, but I guess there's no crying over spilt milk. -- James Smith, CCNA Network/System Administrator DXSTORM.COM http://www.dxstorm.com/ DXSTORM Inc. 2140 Winston Park Drive, Suite 203 Oakville, ON, CA L6H 5V5 Tel: 905-829-3389 (email preferred) Fax: 905-829-5692 1-877-DXSTORM (1-877-397-8676) On 4 Dec 1999, Sean Donelan wrote:
