This article describes how to use the Symantec Diagnostic Tool (SymDiag) to detect and resolve common product issues, without contacting Symantec support.
The Symantec Diagnostic Tool (SymDiag) provides the ability to automatically detect whether a system with a supported Symantec product has a known issue or is in an otherwise problematic condition. Each report that SymDiag runs targets a particular issue or question about the health of a Symantec product. The report will yield a status of Error if an issue is found, Warning if there is a possibility of an issue or Ok if the issue in question is not found. Each report contains one or more tests which answer each question that the report as a whole needs to answer in order to yield a general status. The SymDiag scans that create these reports only gather the data needed to determine the conditions of the tests and as a result the scan can often be completed in under one minute.
