Index Server + php

[Anon]

Hi!

I'm using PHP4 RC1 as a CGI on 2000 server and IIS4.

After frequently calling a PHP script using COM to access MS Index
Server (see below) I receive the following error:

"Warning: Invoke() failed: Exception occured. in E:\foo.php on line
16"

where the CreateRecordset method of the Query object is called.
Plz tell me what is wrong with my code

 $q = new COM("ixsso.Query");
 $q->Query = "mush";   										
$q->Catalog = "ibts";     											
$q->SortBy = "rank[d]";													
$q->Columns = "characterization, path, write, DocKeywords, filename";	
$q->MaxRecords = 200;				

$rs = $q->CreateRecordSet("nonsequential");

Thanks
