Slow Windows Startup Timings

The process for Windows starting up based on a client joined to a Active Directory domain and using a DHCP address:
1. User powers on the machine which goes through a POST (Power-On Self-Test) sequence. The POST sequence displays information about the BIOS, and the amount of physical memory installed. The system will also attempt t initialize PCI cards. Once the POST sequence has completed, you will normally see a basic table outlining the system configuration including disk information, and PCI card information.
2. The system goes through the process of acquiring a DHCP address, normally referred to as DORA:

  • DHCP (D)iscover

  • DHCP (O)ffer

  • DHCP
