Error From Migrating

I promised a friend that I'd help him move his site over to a new server. It uses ASP and an MS SQL database and is on a Windows server. I moved his files over and for some reason I'm getting the following error and was wondering if someone could help figure out how to fix it.Code:
Microsoft OLE DB Provider for ODBC Drivers error '80040e21'

ODBC driver does not support the requested properties.

/default.asp, line 86
Here is the code where the error is generated from (the recordset is line 82):Code:

function rs_readonly( sql )
dim rs
set rs = createobject("ADODB.recordset")
' rs.cursorlocation = adUseClient
' response.write( sql & "<br>" )
' response.write( "<p>" & sql & "</p>" )
rs.open sql, connection, adOpenKeyset, adCmdText
set rs_readonly = rs
end function
Also, this is in the global.asa file. Can somebody tell me what this means/does?
