Dan,
Suppose you have two external line provided by different ISP, normally
two ISA EE is needed
but by using DNS round robin, you can deploy two ISA SE for load
balancing..., that's my
point.
HTH,
Roy

No, you would still have that "one default gateway" problem...
Besides, that feature is only for DNS entries that "you" control, not
external.

Dan,
Your problem is due to DNS round robin feature, and it shall be
solved by Stefaan's great
guidance.
On the other hand, don't you think we can utilize such round
rodin as a good feature to
implement NLB to balance connection to multi external interface
by using ISA STD version
only?
HTH,
Roy Tsao

Good article, it sounds very similar to my scenario. I
already had the "enable netmask ordering" option enabled, so that is not
the problem. Do you think it might be because each of the 10.6.x.x
subnets have a mask of 255.255.255.0?

Subject: [isalist] wpad.dat DNS entry
I'm having a serious problem here with the wpad name
resolution. I moved it from being sent out via DHCP to DNS per Jim's
recommendation, which seems to have speeded up some things, but is now
unreliable and causing problems.
The problem appears to be the multiple internal
subnets... Here is a diagram of how it is laid out:
Internet
|
ISA Server --- Internal Network 1 (10.20.1.1)
|
Internal Network 2 (10.6.254.90)---- 10.6.8.x Subnet
|--
10.6.9.x Subnet
|--
10.6.10.x Subnet
|--
10.6.12.x Subnet
|--
10.6.14.x Subnet
|--
10.6.15.x Subnet
I entered two Host (A) records for wpad, one for
10.20.1.1, and another for 10.6.254.90.
Frequently I run across computers on the 10.6.x.x subnet
where the FWC cannot automatically detect the ISA server, so I ping wpad
and it resolves to the 10.20.1.1 address instead of the 10.6.254.90
address that it is supposed to get. I try repairs and such, it keeps
resolving to the wrong one. When I reboot the computer, it resolves to
the correct IP and works properly. I reboot the computer several times,
and it gets the correct address. But, I'll hear of another computer
having problems, and I'll check and it is the same problem. This is not
going to be pretty over the next few days as teacher come back to work
after summer vacation.
What is the best way to resolve this? Change it back to
DHCP, customize host files, etc?
