Trust between two domains<br />
We have two domains on our network. Domain A and B. There is one way trust between domain A and B. Recently we have experienced network issues on domain B and i had to reconfigure network cards on one of the hosts. I think that threw off trust relationship between both domains. I fixed the network related issues, but now users on Domain B are experiencing authentication issues. &nbsp;I checked trust settings on Domain B DC, it seems to be down. Could i have reset the trust after i reconfigured the nics? How to reestablish the trust without further issues? Thank you for your advice in advanced. <br />
<br />
Follow up question:<br />
Domain B has a DC with class A DHCP scope. When i reconfigured the nic cards, DHCP role went down. Scope is down. Doesn't seem to want to come back up. Any suggestions how to troubleshoot this issue?

Trust Relationships

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).

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

A domain controller is a server that responds to security authentication requests within a computer network domain. It is a network server that is responsible for allowing host access to domain resources. It authenticates users, stores user account information and enforces security policy for a domain

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.
