I am using ISA server 2000 in windows 2000 server. everytime I access/browsing the website either from server or from the client (workstation) in the event viewer of the W2K server always showing the error message as following (application log) ============================================== "The ISA Server services cannot create a packet filter 202.146.255.5. 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." ======================================= Its look like there is a conflict between LAT and w2K routing table. Help me to solve this problem. This is my first time using ISA server. Thanks you in advance. Regards Bias
