So I have an Amazon EC2 box running Windows Server 2008 with Active Directory installed on it. I also have a Windows 7 virtual machine, which is set to use the Active Directory box as its DNS and WINS server. I'm trying to join the virtual machine to the domain, and I'm asked for authentication. I give authentication, wait a minute, and I get an error saying:

The following error occurred attempting to join the domain "":

The network path was not found.

How can I fix this so that I'll be able to join the domain?

Problems like this are always due to DNS.

Try the following commands from the PC you are trying to join to the domain

nslookup ad

They should both resolve if you've got everything configured correctly.

It would be beneficial if you would include the output of ipconfig /all and ip details for your domain controllers within your question.

These both resolve for me, but adding still results in the message in the question. – Kev Jul 16 '14 at 2:41

Never tinkered with EC2, but my 2 cents,

From your Virtual client machine, do a ping ad or ping, if its able to ping, then it means that the server and client are reachable.

Also check the subnet and other network settings to ensure that they both are on the same network

Other issue being the COnnection Specific DNS Suffix and DNS Suffic search order

Ping is disabled on the box, but I know that they can talk to each other. – Chiggins Feb 21 '11 at 14:48
are you sure that ping is disabled?? I've experienced on x64 Win machines that you may have to open the command prompt in administrative mode to access some commands. (ipconfig and ping included ) – user67714 Feb 21 '11 at 16:34
@Chiggins ping disabled? Why? It's a diagnostic tool designed to help you resolve issues exactly like this. Disabling it serves no purpose. – Bryan Apr 1 '12 at 8:40

Just disable the second NIC, join the domain, and restart. Then you can re-enable the other NIC.

this has worked for me in XP not sure if it will on Win 7

try running the windows 7 VM in safe mode and then adding it to the domain.

Tried that out, but sadly didn't work. – Chiggins Feb 21 '11 at 14:49
