Description

The server name cannot be resolved.

Message #

The server name cannot be resolved.

Error: %2

Server name: %4

Guidance:
The client cannot resolve the server address in DNS or WINS. This issue often manifests immediately after joining a computer to the domain, when the client's DNS registration may not yet have propagated to all DNS servers. You should also expect this event at system startup on a DNS server (such as a domain controller) that points to itself for the primary DNS. You should validate the DNS client settings on this computer using IPCONFIG /ALL and NSLOOKUP.
