Component Fails When Used Within ASP

[casdsoft]

Question:
I am maintaining a website that use third party DLLs, VB programs and SQL SERVER, I am using windows 2000 server with service pack 4. Components which use database has been defined in DLL is being accessed in ASP pages.
it fails to run when I use these DLL component within Active Server Pages of the project.

Same project works nicely with Windows 2000 advance server in some other place. I have done all similar security settings and user permissions in my m/c, DB & DSN is working fine as I accessed it with a test page.

but it fails to run when I use these DLL component within Active Server Pages of the project, which are also part of my project.
I am receiving following types of error in different pages: -
