Claim One:
1. A computer implemented method for resolving a computer configuration or system state drift by reducing diagnosis scope from a large set of change records to a smaller set of change records in computer based systems, comprising: cleaning irrelevant changes from said large set of change records based on domain independent rules applied by one or more computers against said large set of change records to produce a cleaned set of change records; extracting and normalizing features of change records in said cleaned set of change records; removing records from said cleaned set of change records based on change patterns of said extracted and normalized features, wherein the change records comprise change data which affect configuration and system state drifts; clustering remaining change records into smaller clusters; identifying at least one change record from the clusters as a source of drift; and resolving the drift by correcting a change associated with the at least one change record identified as the source of drift, wherein the change records comprise change data involving one or more of changes in configuration and system files, operating system (OS) configuration changes, changes to network services, and changes to file systems.
