If in the Event Viewer on your computer or domain server encountered the following error messages:

• The computer PC-NAME had tried to connect with the server \\2003SERVER using the trust relationship established by the domain DOMAIN-NAME.
• The computer has lost the correct security identifier (SID) when the domain was reconfigured. Reestablish the trust relationship.
• The time provider NtpServer encountered an error while digitally signing the NTP response for peer 192.168.0.XX: 123.
• NtpServer not able to provide the client with one hour in protected mode (with signature), then ignore the request. Error The specified user does not exist. (0x80070525)

means you have to redo the station to join the domain indicated.
These errors are caused due to reinstallation of the domain server or workstation, it is not enough that the domain or computer have the same names because the join is valid. So if your computer is already on domain should exclude it and reinsert it. In this case we must be careful to restore the data to the user profile because it will create a new one (will discuss this in the next article).
