An computer program product and a method is presented for diagnosing hardware and software problems on a network computer through the use of a diagnostic adapter card. The diagnostic adapter card is installed in an open slot in the system bus and thus has access to all the network computer electronics and peripherals. Diagnostic programs are run and the results are logged. By analyzing these results, the source of the problem can be determined and reported for service or repair. The diagnostic adapter card contains its own processor, read only memory, random access memory, and interface logic for connecting to the system bus, a set of external wrap cables for peripheral connector testing, and an external reporting device. Some tests require use of a wrap cable to connect two or more ports together. Other tests, such as system bus timing or memory integrity, do not require the use of wrap cables.

The invention finds matches in ordered sequences, e.g. program function call stacks from anomalous software program executions for discovering related or identical software flaws and possible known solutions. Call stacks are matched after removing recursive and uninformative subpatterns, e.g. names of common error handling routines, to see if they were generated due to the same possibly known problem. Sequences statistically unlikely to be matches are pruned from the search. Matches found earlier in the sequences may be weighted differently, e.g. to be more important in call stacks, than other matches. Sequences are indexed so that those relevant to a query are identified automatically without detailed exhaustive search. Maximum matches are found by optimizing a cost function based on weighted sequence similarity.

When a hardware or software problem reoccurs, a customer is rarely able to remember and repeat the process that was performed by a customer service representative to correct the problem the first time. By capturing desktop events and/or one or more other available data streams during the first customer service engagement, and making a document containing that data available to the customer, the customer can solve a reoccurrence of the problem without having to contact the customer service center. The captured data is integrated into a single multimedia document, which has an indexing capability, highlights critical information, and includes annotations and/or comments. The integrated multimedia document can be distributed to the customer by the customer service representative during an engagement, over a customer accessible network site visited by the customer, or in a CD-ROM provided with the product.

An approach is provided to utilize experiences of a user community to identify software problems and communicate resolutions to such problems. Error reports are received from installed software systems in the user community. From these reports, a set of problematic usage patterns are generated, with each of the usage patterns having a confidence factor that is increased based on the number of problem reports that match the usage pattern. The problematic usage patterns are matched to sections of code corresponding to the installed software system with sections of code being identified with problematic usage patterns having confidence factors greater than a given threshold.
