Deploy image task not received

I am able to PXE boot into WinPE.

However, I cannot successfully run any tasks while in the WinPE environment.  The NS will report "Waiting for agent to receive the task" until it times out.

From the client, I check the PECTAgent log and see the following two events repeated:

<![CDATA[m_client->get_MaintenanceWindows return error -2147467263]]>
<![CDATA[CTaskAgentBase::IsPastCheckTSListTime(): Current Task Server valid until "01/31/13 16:02:08" when the server list will be refreshed]]>

I run Task Manager within WinPE to verify that PECTAgent is started.

The task server is the same as the NS.

From the client, I can ping the TS/NS.  Deployment task handlers are installed on the server as well.

Any thoughts/suggestions?
