A firewall is active between the DPA and the managed system blocking the required WMI tests.
OR 
The managed server is configured to use NTLM only.

WORKAROUND

1. Event capture uses the functional account for the system.
The functional account must have remote WMI capabilities to the target system.

A Firewall is active, blocking the required WMI test. Configure the exceptions in the firewall to allow WMI.

2. If the target system does not have UAC turned on, the functional account for this system may be the built-in Administrator account, a domain Administrator, or a user in the Administrators group.  If the target system does have UAC turned on, the functional account for this
system must be the built-in Administrator account or a domain Administrator. After updating the UAC settings, the system must be rebooted.

3. The manged system may be configured to use NTLM only.
Configure it to use NTMLv2 only.
