TinyCore Linux: Build a ‘Persistent’ Web Server

KB ID 0001697 Problem Recently I was building a lab for testing load balancing, and needed some web servers, I could have built three Windows servers, but I wanted to run them in EVE-NG, so they had to be as light as I could make them.

EVE-NG: Committing / Saving Qemu Virtual Machine Settings

Essentially you see this error...

Domain Controller Wont Boot: Stop Code ‘0x00002e2’

KB ID 0001494 Problem I had this problem after a VMware host upgrade last night, this domain controller would not boot, I tried ‘Last Known Good Configuration’, I tried ‘Safe Mode’ it would not boot. More out of desperation than procedure, I tried to boot to ‘Directory Services Restore Mode’ and it booted up (hooray!) I tried all the client’s usual passwords, and could not log in, I messaged...
