When ever I try to start a IIS application the rec the following three
msgboxes:

1
WebClass Designer
Internet Information Server or Peer Web Services version 3.o or later must
be installed to run WebClasses.

2
Microsoft Visual Basic
Error during load. Refer to 'F:\program Files\Microsoft Visual
Studio\VB98\Template\Projects\WebClass.log for details

(the contents of the log file is "Line 2: Cannot load control
WebClass1.")

3
Microsoft Visual Basic
'F:\program Files\Microsoft Visual
Studio\VB98\Template\Projects\WebClass.dsr' could not be loaded.

I use Windows 2000 Professional and am using IIS for http. IIS appears to be
working as I can browse and load the default or other web pages.

FIX: Unable to Develop IIS Applications (WebClasses) on Windows 2000

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

a.. Microsoft Visual Basic Learning Edition for Windows, version 6.0
b.. Microsoft Visual Basic Professional Edition for Windows, version 6.0
c.. Microsoft Visual Basic Enterprise Edition for Windows, version 6.0

----------------------------------------------------------------------------

SYMPTOMS
When developing IIS Applications (WebClasses) on Microsoft Windows 2000, the
following error message occurs:

Internet Information Server or Peer Web Services version 3.0 or later must
be installed to run WebClass.
which is then followed by these additional error messages:
Errors during load. Refer to 'C:\Program Files\Microsoft Visual
Studio\VB98\Template\Projects\WebClass.log' for details.
C:\Program Files\Microsoft Visual
Studio\VB98\Template\Projects\WebClass.Dsr' could not be loaded.

CAUSE
The WebClass Designer searches the registry for the Active Server Pages
(ASP) 2.0 Type Library key. By default, Windows 2000 only has the registry
key for the 3.0 version of the ASP Type Library. Because of this, the above
error messages occur.

RESOLUTION
NOTE: The following resolution requires the use of Regtlib.exe, which is
contained in Visual Studio Service Pack 3. To obtain Visual Studio Service
Pack 3, see the following Microsoft Web site:

http://msdn.microsoft.com/vstudio/sp/vs6sp3/default.asp
Registering the ASP.tlb Type Library adds the 2.0 key to the ASP Type
Library registry entry. The asp.tlb file can be found on Disk 1 of either
the Professional or Enterprise version of Microsoft Visual Studio in the
following directory:
Common\IDE\IDE98
Copy asp.tlb to the following directory:
Program Files\Microsoft Visual Studio\Common\IDE\IDE98
Use the regtlib.exe file to register the ASP 2.0 Type Library.

STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed at
the beginning of this article. This bug was corrected in Visual Studio 6.0
Service Pack 5.

You can download Visual Studio Service Pack 5 from the following Microsoft
Web site:
Visual Studio Product Updates

MORE INFORMATION
Some Microsoft applications, including Visual Studio 6.0 Service Packs 2 and
3, register the asp.tlb 2.0 Type Library automatically. The stand-alone
Visual Basic 6.0 does not.

In W2000 Pro. the website containing the webclass must be made an
Application and the Application Protection should be placed to 'IIS
Process'.
