WHAT I can to do to this message ? The ISA Server services cannot create a packet filter 200.176.3.215. This event occurs when there is a conflict between the Local Address Table (LAT) configuration and the Windows 2000 routing table. Check the routing table and the LAT to find the source of the conflict. SEI-Serviço Especializado em Informática J. Rafael Narezzi It Manager http://www.sei.inf.br http://www.indaia.net
