ASP discord with IIS?

I can't find anywhere to obtain the solution of this problem.
ASP doesn't woking in IIS.

I have investigated many potentially related objects, such as IIS & NT & Security ...
The problem is Security disaccordance between IIS & NT.
When IIS is initially installed, it create two new account IWAM_MACHINENAME and IUSR_MACHINENAME.
The first is newly added since IIS 4.0 because of integration between IIS and MTS, which is employed to access MTS from IIS.
The latter is used for anonymous accessor of IIS.

The problems are occurred by these two NT accounts. Why?
Because these two have only Guest privilege.
If I change those privilege as administrators, ASP work well.
And once it started, all requests are processed normally with Guest privilege.
So I could guess that the problem is generated while first try for running ASP.

Likewise IWAM_XXX affects running MTS package, that is "Run in Separated Memory Area"-checked IIS application.

How can I degrade ASP's required-access privilege into Guest?

(This has nothing to do with programming but very important for me, a programmer)
