I think it is fair to say that the Russian Army was unprepared for WWI, however, I think to ascribe this totally to the regime is somewhat unfair. Obviously, to use Harry's maxim the "buck stops here" so the blame for any unpreparedness always falls on the government in power. But the same could be said of France and England as well (which were equally unprepared for what followed). Undoubtedly at the commencement of the war Russia was undersupplied with weapons, but unlike Germany which had been preparing for war for a number of years and was fundamentally a militaristic regime, Russia's army was a peacetime army so just like the US (both in WWI and WWII) it took time to ramp up. By 1917, however, wartime production was supplying the front lines with adequate supplies of machine guns, artillery, planes and tanks. Should Nicholas' government have recognized the German threat earlier and begin rearmament sooner, probably. Then again Russia's defensive strategy was always to be based on shear numbers of its army (which is the strategy followed by the soviets in WWII) and, in any case, the general popular wisdom was that it was going to be a short war. Up until WWI all wars were relatively local affairs which did not deploy the massive forces over lengthy front lines and did not involve the enormous logistical problems and total national mobilization which characterized WWI (the first real modern war). Up until WWI Russia's wartime experience involved regional skirmishes like the Russo-Turkish war and before that the Crimean War so there really was no experience on which to fall back on (frankly I believe that at the outset the German generals probably outmatched the Russian general staff) and unlike the Germans the Russian general staff had not developed elaborate wartime plans in advance.
