"HTTP 500.100 - Internal Server Error" When You Try to Access a Provider

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: 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.
