Or
How about how to get rid of MS Proprietary Clunky products like Exchange and SSO needing to support MS authentication and use lighter weight, multi-platform alternatives?
The Domain Server architecture and Exchange are horrors. Especially for smaller offices.
After using MS Server since NT 3.5 (1994?) I'm migrating to Linux and abandoning MS Windows Update Server.
Migrated LONG ago from MS Mail, then Outlook + Exchange to MDaemon on Windows and a succession of mail clients. Yes I know Outlook and Exchange do appointments etc.
I don't miss Sharepoint either.
I used to install MS Solutions, had MCP cert, wrote and gave training course in NT Admin etc. No longer.
