Hi<br />
<br />
Is file and printer sharing enabled in advanced nic properties?<br />
Is network Discovery enabled?<br />
All Yes? Temporarely disable the firewall and test again....<br />
<br />
Cheers

<div>
Can you ping any of the devices from each other?<br />
<br />
Is your Server issuing out IP as expected?<br />
<br />
Can you ping your gateway?<br />
<br />
Have you check that there is firewall turn on?<br />
<br />

Can you post IPCONFIG /all from server and one affected workstation ?
</div>


<div>
What happens when you try to ping? And what exactly do you try to ping?
</div>


<div>
If I ping host name, times out.<br />
If I ping ip address times out.
</div>


<div>
And if you try to ping a system outside of your network? You could also try going into TCP/IP properties and unchecking IPv6 (do not uninstall it).
</div>


<div>
I haven't got that far with it as yet. &nbsp;It is only a test domain.<br />
If I try to ping outside transmit failed, failed in transit.<br />
<br />
would expect that though.
</div>


<div>
The way this is sounding, and correct me if I'm wrong, NONE of the devices can ping, correct?
</div>


<div>
NONE of the devices can ping at all!!
</div>


<div>
I asked you twice to post Ipconfig to help us understand your configuration If you don;t want to do it for some reason, it's going to be hard to help you
</div>


<div>
Are all of these devices connected to the same switch? And if so, is the switch working properly?<br />
<br />
Bear in mind that I am making the assumption that the DC is also serving as the DHCP server since there is no mention of a router or a hardware firewall.

<div class="content wysiwyg-content">
Created Server 2012, DC, AD/DNS/DHCP are working fine.<br />
Added 7 devices to this domain with no issues.<br />
<br />
Devices have appeared in AD/DNS - and all appeared fine.<br />
<br />
I could ping from server, also from each device, no issues.<br />
<br />
Came in today and cannot ping anything, all services look ok, nothing on event viewer.<br />
<br />
Have restarted DC - no change, can ping nothing.<br />
when I use arp -a, they all appear.. Any ideas?

Created small domain - But now cannot ping any of my devices that i added

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

Active Directory (AD) is a Microsoft brand for identity-related capabilities. In the on-premises world, Windows Server AD provides a set of identity capabilities and services, and is hugely popular (88% of Fortune 1000 and 95% of enterprises use AD). This topic includes all things Active Directory including DNS, Group Policy, DFS, troubleshooting, ADFS, and all other topics under the Microsoft AD and identity umbrella.

Active Directory

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.

The Dynamic Host Configuration Protocol (DHCP) is an auto configuration protocol used on IP networks and an extension of the Bootstrap Protocol. DHCP allows for computers to be configured automatically to communicate with each other over an IP network without the need for manual setup by a network administrator. The implementation of DHCP relies on a DHCP server to hand out network configuration information to DHCP-capable clients that request an IP address (and other information required or useful in communicating with other devices on an IP network). In addition to an IP address, common configuration information served over DHCP includes a default gateway, subnet mask and DNS sever(s).
