Error in SCCM 2007 – Failed to Run Task Sequence 0×80072EE7

When I deployed operating system task to group of computers I received this error:

Failed to Run Task Sequence!

?

In log file of SCCM client X:\Windows\Temp\SMSTSLog\smsts.log I fund this:

<![LOG[Setting wizard error: An error occurred while retrieving policy for this computer? (0x80072EE7). For more information, please contact your system administrator or helpdesk operator.]LOG]!>

?

The reason was that DHCP server was unavailable. I configured static IP in Task Sequence Wizard and the Task started immediately.
