Running Presentation Server 4 on top of Server 2000 Sp4 with WI 4.0. I'm constantly getting an event in the Application log that reads: An error of type "IMA" with an error ID of "0x80000001" was reported by the XML Service at address http://server:80 I've searched and have found it mentioned, but have not seen a solution yet, does anyone have any ideas?
