It is possible that the same recommendation would solve your problem as it does affect sbRIO boards as well. The issue is very specific though and only afffects boards with a static IP address defined, running NI-TimeSync 1.1 with some other settings. If you're using a static IP address on your 9606 and have NI-TimeSync 1.1 installed, I would definitely recommend upgrading the version of NI-TimeSync on your host PC and then on your 9606.
