The information in this article applies to:

  • Microsoft Internet Information Server 4.0
  • Microsoft Internet Information Services 5.0
This article was previously published under Q278604
We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 6.0 running on Microsoft Windows Server 2003. IIS 6.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site:

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

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