Register .net dll in server 2003 use by classic asp

[david_cheong2002]

i have the problem where i try to call the create the server object in my asp page.

I already register the dll using .net framework v2 (regasm) and i add this code in my asp.

set a = server.createobject("Mobile88Hash.sHa1HaSh")
response.write a.GetAuthor & "<br>"
response.write a.ComputeHash("appleM0001236A000000014500MYR1")

but i get this error message

Server object error 'ASP 0177 : 80070002'

Server.CreateObject Failed

/test.asp, line 6

80070002

the component is working fine in the window XP (i try at the development PC and also non development PC) all is workable, but when i try in the window server 2003 standard edition, cant work........

Some body told me is the permission problem and i try to do quite some modification on the registry and the file permission, stil unworkable....

can any one help me????????
