Okay, this is one of the oddest problems I've had to date with Reporting Services 2000.
I have an ASMX that calls the Reporting Services ASMX via the Render method. The report path, format, deviceInfo and parms are populated as expected. The result the values are Nothing/Null null.
The method call throws an SOAP exception, and drilling into that, I get to this.

Most likely one of the mandatory parameters is missing or a parameter name
in the parameter collection == null, which is not allowed. Only parameter
values can be null, but parameter names in the collection always have to be
!= null.
