Thanks a lot for the valuable information. I am very happy to see such a fine summary of the lecture that Prof. R. N. Iyengar delivered.
With deep regards

The archery competition for Draupadis' marriage was held in a town specially built in the north-eastern direction of the capital and it was named shishumaarapura, figuratively indicating that the constellation had changed its orientation as seen from earth, due to Dhruva moving away.
tataḥ purajanāssarve sāgaroddhūta nissvanāḥ|
śiśumārapuram prāpya nyaviśan teca pārthivāḥ||
prāguttareṇa nagarād bhūmibhāge same śubhe|
samājavāṭaḥ śuśubhe bhavanaiḥ sarvato vṛtaḥ|| MB Ādi Parvan ( Ch 176 v 15,16)
Hence dhruva moving is a necessary condition stated in MB, but by itself not sufficient to fix a specific year for the War.
Sunil BhattacharjyaTo my understanding, Thuban was the Pole-star from about 3700 BCE to about 1900 BCE, i.e., till when Kochab took over as the pole-star. Kochab remained as Pole-star from about 1900 BCE to the time when the present-day pole-star Polaris became the pole-star in around 500 CE and Polaris will remain so till around 3000 CE when Gemma Cephei will take over as the Pole-star.Regards,

From this can we say that the date of the Mahabharata war should fall within the period 3700 BCE to 1900 BCE.? . This way, will we not be able to eliminate the dates before 3700 BCE and also the dates after 1900 BCE.

Shivraj:b) Does Mahabharat tell us about the change in the pole star?
c)If so does this information help us in dating the war?
RNI:It provides information on when MB war could not have occurred. The default option for calling a star "dhruva" should have been that it was "fixed" being too close to the North Celestial Pole so as to look fixed in naked eye observations. This was possible for only alfa-Draconis which was only seven minutes away from the Pole in 2830 BC. The name for this star originally was Abhaya as per Tai.Ara. We have to infer that the fixed nature of the star was observed and it acquired the name Dhruva during 2800-2900 BC. Once the star had such a special quality, the adjective became the name itself. So MB statement (Bh.P 3.17) above could not have
been valid before 2830 BC.

Thanks for the illuminating answers! And they make me ask more questions:
Shivraj: a) Do we have any information from our texts why the name changed from Abhay to Dhruv?
b) Is there no association of Dhruv with the pole star prior to Mahabharat?
c) Since the word dhruv is known from RgVed why would this significant name get associated with the pole star only during the Mahabharat period?
Regards,
Shivraj
