I am experiencing something strange with my ISA box my users keep losing Internet access. My connection can be running really fast, then suddenly all my users get timeout messages, it stays this way for a few minutes then springs back to life as fast as before.
I know for a fact that I am not losing my ADSL connection, I have a test machine out side of the network directly connected to the router that can still surf whilst the ISA server is down.
The only error message i get is
The ISA Server services cannot create a packet filter 22.214.171.124. 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.
I have a standalone W2K box running ISA and nothing else. I have one internal NIC using a private IP and one External NIC connected to the ADSL Router. The ADSL Router is running NAT so my external NIC is given Private IP as well.
I have tried a clean reinstall but still the same error occurs - does any body now why??

I have read conflicting reports about this external resource in the LAT. My working configuration does not have any external interface address in the lat. My believe is the lat should only house the address from the internal interface back (nothing public)
I am experiencing the same problem with clients getting dropped randomly. I also run a vpn off of the machine which provides dhcp addresses in the same range. Is there something I have to be careful of here?
I have never ran vpn before so I don't really know if you have anything to be careful of.
I think my problem was with my Internal nic.
My internal nic had been set to get a IP address from my Dhcp server, I read in the deployment guide that the internal nic should have a static IP address assigned to it instead.
When I went to change the IP address I found that somehow the default gateway had been set to the IP address of the Router, so I set a static IP and blanked the Gateway and this seems to have solved my problems.
