Abstract: A method, computer program product, and computer system for managing and tracking commands associated with a change on a managed computer system. The managed computer system receives a log-on of an administrator onto the managed computer system, determines the lockdown level of the managed computer system by querying a managing computer system, and retrieves a list of authorized commands under the lockdown level from the managing computer system. The managed computer system determines, by querying the managing computer system, whether an authorized change on the managed computer system exists. The managed computer system removes the lockdown level to receive from the managing computer system authorization of commands that have been locked down, in response to determining that the authorized change exists. The managed computer system sets the lockdown level with the authorized commands on the managed computer system, in response to determining that the authorized change does not exist.

Abstract: A processing device of an information processing system is configured to automatically determine availability status for multiple work stations of an enterprise by monitoring information technology resources associated with respective ones of the work stations. The processing device is further configured to generate availability indicators for the respective work stations based on the determined availability status, and to provide the availability indicators for presentation to one or more users. For example, the processing device may be configured to automatically determine availability status of the work stations by monitoring network ports associated with respective ones of the work stations, with a given one of the work stations being considered unavailable if the corresponding network port is in use and otherwise being considered available.

Abstract: Stalling of segment downloads during adaptive bandwidth switching where bandwidth drops in the midst of download of a segment is overcome by downloading segments in multiple subsegments via multiple download operations. Additionally, bandwidth monitoring can be performed in between each subsegment download, and if bandwidth has fallen substantially, and the segment download is not near completion, then the already-downloaded subsegments can be discarded, and the segment download can be restarted from a lower-quality variant.
