zabbix 1.3.5 not updating items

[rbmf]

I have zabbix installed and configured with a few hosts. The agents are installed on the hosts both windows and linux. Looking at the Monitoring nothing is ever been updated. Here are some errors in my /tmp/zabbix_server.log

  2695:20070417:144934 Getting value of [vfs.file.cksum[/etc/passwd]] from host [zabbix] failed
