Connection to posgresql database works under windows scripting host but not IIS/ASP

Environment:

=========

  Windows 2000 server running IIS. This server is a domain controller. This server is runnning version 7.2.5 of the postgres odbc driver.

  Debian Linux server running a postgres database

 

ASP script:

========

 

Function nugget_forum(column)
    start_nugget column,"::Rumour Mill"
    Set conn = CreateObject("adodb.connection")
    conn.ConnectionString  = "DRIVER={PostgreSQL};sERVER=10.11.2.5;port=5432;DATABASE=dbname;UID=uid;PWD=pwd;"
    conn.Open
    'Set rs = CreateObject("adodb.recordset")
    'querystr = "SELECT * FROM ib_forum_posts;"
    'rs.open querystr, conn,3,3
    Conn.close
    end_nugget(column) 
end Function

 

script run under windows scripting host

==========================

 

When I run this script under windows scripting host I get a connection and am able to retrieve data.

 

Set conn = CreateObject("adodb.connection")
conn.ConnectionString  = "DRIVER={PostgreSQL};sERVER=10.11.2.5;port=5432;DATABASE=dbname;UID=uid;PWD=pwd;"
conn.Open
Set rs = CreateObject("adodb.recordset")
querystr = "SELECT * FROM ib_forum_posts;"
rs.open querystr, conn,3,3
do while not rs.eof
  wscript.echo rs.Fields(0).value & ":" & rs.Fields(1).value & ":" & rs.Fields(12).value
  rs.MoveNext   
loop
Conn.close

 

The error

=======

 

When I run the script in an ASP I get the following error.

 

Microsoft OLE DB Provider for ODBC Drivers (0x80004005)
[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
/intranet/default.asp, line 35

Line 35 is the conn.open statement

 

 

I initally thought that this might be a permissions problem. I added IUSR_SRV-AMB-DB temporarily to the domain admin group and restarted IIS, but it didn't make a difference.

 

I'm at a loss. Can someone please help me.
