Was that last photo taken from Poisk?

Yes, from MRM-2's Aft-Port facing hatch porthole.

Are you sure? It looks an awful lot like Zveza's Nadir side to me.

Could the docking problems during the first docking attempt of 38P be related to the debris that could be seen floating away when the Soyuz 23S was de-docking from the Service Module for its relocation? See my post

Nope, it's definitely taken from MRM-2. If it were taken from SM Nadir, the Aft portion of the SM would not be visible.

Ah yes you're right. I should have payed more attention to the exposed facility on the far right -- that well constrains the point fo view.

Here's some hi-res photos of the docking (see pages 28 to 30).

This photo was also taken from MRM-2. As you mentioned, the SM's Port exposed facility on the right shows that the photo was taken from MRM-2 - if it had been taken from SM Nadir, the exposed facility would not be visible (and DC-1's Aft hatch porthole faces Starboard, not Port.

The reasons of failure in the docking of cargo spacecraft "Progress M-06M" to the ISS (Russian news)
http://www.federalspace.ru/main.php?id=2&nid=11820

Interesting news.

due to noise, communication channel and the astronauts accidentally pressed one of the buttons on the control panel

With regard to its modernization in the Progress M 08-M "and" Progress M 09-M, Soloviev said that "we think of the evolution.

Roscosmos PAO: "RSC-Energia Concluded about Interruption of Progress M-06M Rendezvous to the ISS".
Quote
Accident commission of RSC-Energia completed investigation of the failure caused interruption of Progress M-06M rendezvous to the International Space Station on July 2, at 20:20:42.
The commission concluded that the rendezvous failed due to unauthorized command "Dynamical mode abort" in the backup manual approach control loop of the Progress.
The command was generated because of interference in the TORU metric wave signal link and pressed button "Operation" on the TORU panel in the ISS Zvezda module.
To avoid similar situation in the future, relevant updates have been implemented for Progress M-07M slated for launch in Sept.
For the next cargo vehicles to fly, additional blocking for this command has been introduced.

From ISS On-Orbit Status Report for 23/08/2010:

Progress M-06M/38P Commission Report:
According to the now published Russian Commission report on the aborted 38P rendezvous approach on 02/07, the failure was due to the KURS automated rendezvous & docking system's receiver (KURS-P) on 38P being shut down by an automatic emergency command when the transmitter on the ISS (KURS-A) was not activated at the same time as KURS-P (at 8 km). This caused the latter to receive only noise, resulting in an emergency shutdown. Subsequent activation of KURS-A then squelched the noise, allowing 38P to approach to 2.8 km, but the system still contained the emergency command which cancelled the standard KURS test planned at this point. 38P then flew by the ISS on its passively-safe flyby path (as per ballistic trajectory design), without requiring any abort burns. Two days later (04/07), 38P docked successfully to the SM Aft port under KURS autopilot control. To prevent noise from getting into the KURS receiver in the future, it will be activated much later, at 3 km (just before the test), and the transmitter at 8 km. The ground will also verify that KURS-P on Progress is receiving a strong signal, before the crew starts their steps. Also, in an unrelated issue, one of the three channels on the ISS-based command unit has an anomaly, and it will be replaced. For Progress M-07M/39P docking, this unit will be used in the two-channel configuration.

There is no Kurs-P on Progress, not Kurs-A on ISS, the story has them reversed.
