ISA Application Error in the Event Log
Posted on 2003-11-05
We are seeing a ton of errors in our event log under the application menu. I don't know what this error is or how to fix it. Our ISA server sits inside our Checkpoint NG firewall and all of our network nodes have the ISA firewall client installed which directs them through the ISA server which in turn sends the requests out the firewall. All of our network IP's (except for Network Servers and ISA) are explicitly denied in the firewall to force the network clients to use the ISA server as the gateway. The other day we noticed these errors in the application log and also saw a bunch (100 or so) routes in our routing table on the Windows 2000 server running ISA. We cleared the routing table and now we just see the errors (no routes are being added at this time). Thanks for any help. Here's the error below. This is just one of many different IP addresses we are seeing.
Event Type: Error
Event Source: Microsoft Web Proxy
Event Category: None
Event ID: 14120
Time: 10:59:06 AM
The ISA Server services cannot create a packet filter 18.104.22.168. 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.
