Problem running ISA en IAS on the same server

Today I had some problems running ISA 2004 en IAS on the same server. At the beginning the customer was running ISA 2000 and IAS on the same server without any problems. By incident, the customer was forced to upgrade his ISA. They had a 2004 license, so ISA 2004 it was.

I noticed that ISA 2004 puts a “Default ISA policy” with the highest priority in the remote access policies. The rule blocks all RADIUS requests, so I had to manually remove the access policy. After the removal everything was working fine again.

I had to change the configuration in the ISA server again and the “Default ISA policy” came back in IAS. So I had to delete the rule again. I also tried to change the priority of the rule, but the “Default ISA policy” gets the highest priority again after applying a change in ISA.

I cannot find anything specific about this problem on the internet, so maybe someone experienced this before and can provide me with an answer to disable this behavior.
