These are based on actual, real, true events, which I’ve been asked to help resolve in some capacity over the past three weeks:

  1. Do not let someone create your VM using an unknown template which contains leftover remnants of a previous SCCM site installation, and dozens of unknown changes for which the site admin has no knowledge what happened.
  2. Do not let someone create your VM and join it to an AD domain under an OU with a bunch of linked GPO’s which are undocumented.
  3. Do not let your boss approve another department’s request to take ownership of your SCCM SQL Server instance without prior discussion or them being advised as to what SCCM is.
  4. Do not let another engineer start building the site before you’ve provided him/her with the design document.  Especially when it includes Intune integration and they go ahead and set Intune as it’s own MDM authority, without discussing anything with you in advance.
  5. Do not recommend an SCCM site installation to a customer after a sales person insisted it was the “perfect fit” for their 10 desktop computers, when all they wanted was to manage software updates.
  6. Do not recommend to a customer that they’re fine with allowing their Primary site server VM, running on a Hyper-V failover cluster, to fail over another node, on another cluster, on another continent.

    1. Hi Matt – I sure can. So, in this particular case, the SCCM infrastructure and SQL instance are (or were) under the same team as far as ownership/administration. Then a new team lead was hired, and decided to grant full ownership of the SQL instance to the DBA team (separate group). The DBA team scheduled a weekend upgrade of the database from 2012 to 2016 SP1, without ever once discussing with the SCCM team. What could possibly go wrong? 🙂
