auto increment problem

I have had my server changed from windows server to linux server. So i had to backup my db. Then when i was importing mysql db, i had some problem in my web site.

there is an error like:

Warning: Duplicate entry '0' for key 1 query: INSERT INTO watchdog (uid, type, message, severity, link, location, referer, hostname, timestamp) VALUES (0, 'php', 'Duplicate entry '0' for key 1\nquery: INSERT INTO watchdog (uid, type, message, severity, link, location, referer, hostname, timestamp) VALUES (0, 'access denied', '<em>node</em> denied access.', 1, '<a href=\\"/drupal/?q=node\\" class=\\"active\\">view</a>', 'http://yasasak.com/drupal/?destination=node', '', '85.101.113.116', 1161198724) in /home/a200610002/domains/yasasak.com/public_html/drupal/includes/database.mysql.inc on line 120.', 2, '', 'http://yasasak.com/drupal/?destination=node', '', '85.101.113.116', 1161198724) in /home/a200610002/domains/yasasak.com/public_html/drupal/includes/database.mysql.inc on line 120

I've searched the error in drupal.org and I've found something like mine:
http://drupal.org/node/70106
But I couldn't understand where to put auto increment in my tables. I'm a newbie in sql and drupal, so if anyone can help me in a simple kind of way I would really pretiate..

mysql version of backup db is 3.23

thanks a lot..
