Cannot join domain "the network path was not found"

Hi there.

As I wanted to install new Microsoft  Lync Server, I tried to prepare a virtual machine for this. For some reason I used a virtual machine that I tested for some another services, therefore it had some changes on it.

As you know before installing Lync Server your client must be join a domain and when I tried to joined it I faced with this error "The following error occurred attempting to join the domain “ysatech”; the network path was not found "

Before my search, I thought it was DNS problem. I checked DNS but nothing was wrong.

I searched for it and I read some forums answers and I resolved it:

As I said my client server had some changes, the problem was in the NIC but not about DNS or WINS. The "Client for Microsoft Networks" of NIC of my domain network was not checked and it must be checked.
