When I mount Speedlight SB-900 on D600 the flash is somehow blocked/obstructed when fired in any mode.The resulting images are very very dark. Same picture is much brighter when shot without flash. The SB-900 does not fire at all in M mode. The built in flash functions normally in all modes. The SB-900 works fine on other nikon cameras but not my D600. I have checked and rechecked settings (increased/decreased ev) on both the flash and camera. Could this be a hot shoe issue? I am puzzled by all of this because the flash itself will fire.

Assuming your settings are correct as you state I'd suggest this:
Do you have a cable for off camera shooting (or a pocket wizard or similar) ?? Get the flash off the hot shoe and see if it fires properly. If these allow your flash to work well, then you will know the hot shoe is the culprit for certain. Assuming the camera is fairly new (it being a D600 and all) it most likely is not a dirty hot shoe issue.
