Article: Q278604
Product(s): Internet Information Server
Version(s): 4.0,5.0
Operating System(s):

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Internet Information Server version 4.0 
- Microsoft Internet Information Services version 5.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you attempt to access a provider from within an Active Server Pages (ASP)
page, you may receive the following error in the browser:

  HTTP 500.100 - Internal Server Error - ASP error Internet Information
  Services

If friendly HTTP error messages are disabled, you may receive the following error
message when you attempt to run the ASP page:

  ADODB.Connection (0x800A0E7A)
  Provider cannot be found. It may not be properly installed.
  /Nwind.asp, line 10

CAUSE
=====

This error occurs because a dynamic-link library (DLL) that is required by the
Microsoft Data Access Components is not registered.

RESOLUTION
==========

NOTE: This resolution uses a SQL Server OLE Provider DLL (Sqloledb.dll) as an
example. Because the unregistered DLL may vary based on the OLE DB Provider that
you are using, modify step 2 accordingly.

To resolve this problem, reregister the faulty DLL as follows:

1. At a command prompt, change to the C:\Program Files\Common Files\System\Ole
  DB folder.

2. At a command prompt, type the following command:

  "regsvr32 sqloledb.dll" (without the quotation marks)

3. You should receive confirmation that the DLL is registered successfully.
