Sharepoint 2010: failed to connect to the central administrator - login from an untrusted domain and cannot be used with Windows authentication

Question

Our setup: Server1: running Sharepoint Server2: running SQL Server

Our Sharepoint 2010 worked perfectly, and then suddenly the website crashed, and when I tried to access Central Admin, I found the following error in the error log:

System.Data.SqlClient.SqlException: Login failed. The login is from an untrusted domain and cannot be used with Windows authentication. 

I read on the Internet that this happens when the server loses trust in the domain, so I removed the Sharepoint server from the domain and then added it back. Result: The same. There is no decision.

I also tried other methods when people asked to update the host file, but that didn't work either.

To check whether the connection works or not ... I checked the UDL file, where I created the networkcheck.udl file on the computer with the Sharepoint server (Server1), and tried to authenticate with Windows and tried to establish a connection with the Database Server (Server2).
Result: successful connection.

Can anyone explain this. I do not know why Sharepoint will not connect even after successful udl testing.

Answer 1

Since I don't know enough about your farm as a whole, you might be better off looking at it as a non-SharePoint issue.

Do not worry about servers in the same domain?

Like Dennis said any of the passwords is Expired / Changed?

Do you have something other than localhost indicating 127.0.0.1 in your Hosts file?

Mark this topic and think about the problem from SharePoint

Thanks Truez

Answer 2

One of the possibilities of this error may be that the account from which the Server was installed was deleted from the domain or the account password was changed.
