Hi, I´m new to reporting services. I´ve created a report and I can run the preview perfectly in BI Development Studio. I also run deploy perfectly. But when I try to run the report through browser (//servername/Reports) this error appears: "There is an error in XML document (1, 3303). '.', hexadecimal value 0x00, is an invalid character. Line 1, position 3303."

Hi siriux11, Based on the error message, it might be caused by some invalid characters in the RDL file. Please check the XML code around "line 1, position 3303"(In BI Development Studio, right-click the RDL file and choose “View Code” to open the report definition file in the XML editor window). If the problem persists, please post the report definition to us. It will help us to reproduce this issue, and then assist you to resolve it.
