MSXML size limitation

I'm using the following:

source = new ActiveXObject("Microsoft.XMLDOM");

source.async = false;

//Send request string and read the result into the XMLDOM object

source.load(sreq);

This works fine (I get over 4MB back in XML) on my development workstation which is Win2K but on the Windows 2003 server it's cutoff at around 2MB.

So my new question is whether there is something in the Metabase which can alter this to work as it did before under Win2k so I get the larger than 2MB back into the XML document? or am I looking at this completely wrong?

Thanks in advance,
