ASP accessing a C++ dll gives "Request Timed out" error.

Hi,
I have an ASP (not ASP.NET) application installed in Vista Beta 2 (Build :
5384). I have added my domain\user account in the Administrators group.
The ASP application performs this task.

ASP application calls a C++ dll that has some business logic and this dll
fills the SQL Server 2005 database

Comment : When I access the page, it is giving me "Request Timed out" error
when I logged in as domain\user.
It is working fine when I logged in as MachineName\Administrator. [This I
dont want to do]
It is working when I add "http://localhost" as a trusted site. [This I dont
want to do]
It is working fine when I disable UAP. [This I dont want to do]

Can you pl. suggest me some solution for this problem.

Thanks in Advance.
