H9 Combo won't open share on Buffalo NAS, but will open Windows share

[A&S&O]

I've reflashed my H9 Combo (with a newer Vix - 6.1.004) after a power outage corruption.

All seems to be ok, except that I can't open a share on a Buffalo NAS. I can browse to a windows share and open it, and I can see the NAS but it won't open.

Anyone know if there's any issues with later versions of VIX and old NAS boxes?

thanks
