@rdr You found a real bug. Sysprep is not needed, and it would not have helped.
Cause: the image carries the agent’s key and certificate from MMF-LAB2-00.
The agent compared the machine’s SMBIOS identity with that key only when it
had no certificate. A deployed copy has one, so every PC connected as
MMF-LAB2-00 and took its name.
fog-agent 0.1.7, released today, makes the check on every start.
To fix the PCs you already deployed:
Go to FOG Configuration > FOG Settings > General Settings and setFOG_AGENT_DESIRED_VERSION to 0.1.7. Every enrolled agent updates itself,
including each PC that thinks it is MMF-LAB2-00. After the update, each PC sees that it is not MMF-LAB2-00, makes a new
key, and enrolls as itself. FOG matches it to its host by MAC. If FOG deployed to that host in the last 24 hours, the enrollment is
approved automatically. If not, approve it under Hosts > Pending Agents.
The agent then renames the PC to its name in FOG.
Please post back whether the names come right.
