Hi, I have a problem on a QA server that does not appear in the dev server. I checked all setting 1 by 1 and the configuration files and I can not see any differences. I have a report service set up with forms authentication. everything works fine except the report builder. If I try to open it and run a report without changing anything (just to display the default report with the date), I get an rsItemNotFound. The weird thing is that the name of the item looks like this: |n1hcgzy35zwxce555lboyc45|@|/e0911b61-81e0-4f14-9fa2-be9e2988e682|. The only difference I can think of is that my dev server is set up to be accessible only by the machine name and that the QA one is set up for both machine name and IP access. I could not find anything on the web about this error.
