Ok, I have a NLB setup with ISA2004EE with one web publishing rule (trying to start conversion and phase out our ISA2000 server).
Anyway, I know this used to work because I tested it and things were all good, weeks and weeks ago. Now I'm getting 12202 errors when trying to access its publish. I managed to fix it by adding the network set "Internal" to the system policy "Various -> Allowed Sites" but I don't think I should have to. Any reason why this might be happening?
Also, maybe related and maybe not, but I had pings enabled on the array for troubleshooting, and if I pinged the NLB'd virtual address, I'd get double responses as if both servers were responding with the same sequence number. Is this normal or not?
