One thought is to make sure RPC is running on the domain controllers (DCs) that are authenticating Active Directory (AD) accounts. &nbsp;Are the DNS servers referenced by the member servers pointing to the DCs (and only the DCs)?

<div>
logon localy to one of your machine and try nslookup yourdomain.com see if that resolve the DNS servers of your domain, also try to ping the DC using their names and see if that resolve correct. also check the global catalog server.

RPC Server Issue

Several of my servers are having issues logging me in to the domain account on the server. 
I receive the following message. &amp;quot;The system cannot log you on due to the following error: The RPC server is unavailable. (servers are Server 2003 Enterprise)

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
