Inventory Fails to scan

Inventory Fails to scan

I have an XP desktop running in a domained environment with DC 5 loaded on it. I puched the agent to nine other computers on the domain. I then went to inventory to scan the machines. They all fail except for my machine. Five of the machines did not get the agent so I understand why they don't inventory but WHY don't the other 4 inventory? I can remote connect to them with the remote option. They are Windows 2000 or XP machines.
