Global.ASA does not work in IIS7.5

Question

I have many projects written in old classic ASP where Global.asa used to work perfectly fine. Since I have installed Windows 7 with IIS7.5, none of my projects are working.

Below is the code for Global.asa

<Script language=vbscript runat = server>

Sub Application_OnStart() 

dim objConn, connectionString

set objConn = Server.CreateObject("ADODB.Connection") 

connectionString = "DSN=otsDSN; UID=admin;PWD=;"

objConn.ConnectionTimeout = 5

The error comes in this line. Have referred many websites, even IIS.Net but still no luck.

objConn.Open connectionString

Application("otsAppConn") = objConn

end Sub

The error thrown by IIS is

error '80004005' /ot/admin/page1.asp, line 33 and the Application object which used to carry the connection object string in older family of IIS now showing, Provider=MSDASQL.1; instead of complete connection string.

All the projects are listed as Application in IIS7.5 which I could see using the appcmd list apps

Appreciate if someone can help on this..

Answer 1

Managed to resolve the issue after long troubleshooting in IIS.

1. Converted the DSN connection provider to Microsoft Access Driver (.mdb) instead of Microsoft Access Driver (.mdb, *.accdb)

2. Created Connection String in IIS under my website under Custom

   "/commit:MACHINENAME /section:connectionStrings /+"[connectionString='Data Source=localhost;Integrated Security=SSPI;Initial Catalog=otmasterdb;',name='otmasterdb',providerName='Provider=Microsoft.Jet.OLEDB.4.0;']" 
   

   and gave the Connection Name same as the DSN connection

3. Changed the Global.asa connectionString from "DSN=aaa;UID=admin;PWD=;" to "aaa" only by removing the latter portion.
   The new code looks like this:

   Sub Application_OnStart()
           dim objConn, connectionString
           set objConn = Server.CreateObject("ADODB.Connection")
           connectionString = "otsDSN"
   
           objConn.ConnectionTimeout = 5
           objConn.Open connectionString
   
           Application("otsAppConn") = objConn
   end Sub

see if the information in the provided link helps you get some better debug info. About halfway down there is a setting you can turn on that allowed me to see what was behind the error code when I was trying to run a classic asp in iis 7.5 http://learn.iis.net/page.aspx/564/classic-asp-script-error-messages-no-longer-shown-in-web-browser-by-default/.
