Just came across a situation where a server had been updated to Windows Server 2003 SP2 and suddenly their ADAM instance would not start anymore. After looking at it for a while I resorted to actually read the release notes for SP2, and there was the answer:
ADAM SP1 must be applied before updating a Windows Server 2003 box with SP2.
The solutions was described as:
- Uninstall SP2
- Install ADAM SP1
- Reinstall SP2
