Cheers for the explanation for the lack mstask.exe UUID's in 2k3 SP1 and
the links :)

It was Urity's presentation which set me off down the road of looking
at/implementing RPC fingerprinting in the first place :), after the
presentation I thought more people would investigate the
technique.......doesn't seem like many people have, however I find it
quite a useful technique in many situations.

-- SP1 does not show endpoint UUID data for the mstask.exe whereas SP0
has quite a number of entries (typically 20+).

Right, in Windows Server 2003 SP1, the Task Scheduler service
(mstask.exe process) does not register its RPC services on the
ncacn_ip_tcp transport but only on the ncacn_np transport (\pipe\atsvc):

Urity gave in 2004 a presentation on the subject of fingerprinting systems
looking at registered RPC interfaces, you might be interested in looking
at the RpcScan tool and the related presentation:
