I had the same problem. MS told me that ISA SP1 fixed it, but I've heard reports that it did not. I set up DNS on my ISA server to work around the problem. I then pointed my internal servers to the ISA server for resolution. I have had no problems since.

I've created a SecureNAT rule that allow DNS lookup on external destinations to Internal DNS Servers. But it isn't working, it were working on past.
