If NSL is installed in AD mode, slcredman is registered as one of the Network providers and the entries will be added in the registry. Sometimes, if products like Lotus Notes, Citrix are installed after NSL, the user may experience a delay during the login time. To avoid this, the slcredman entry has to be put after those entries. This tool will help to manage the Network Provider entry order without the user having to manually edit the registry settings.
