What are you using in setup for the DNS server?
In the DNS settings do not use anything in this all automatic, and the network settings on M500x2 not set up anything, I have everything on automatic. Just connected the network cable between the router and M500x2, and in this way I can see (in 500x2) I have shared folders on Win7 SP1, and Win7 SP1, I can access the disk on the 500x2.
I stream without any problem.
I keep everything in automatic or should I make any changes?
