How do I access another domain?
By default, the credentials used for a Machine are applied as credentials for the domain where the remote Machine is located. It is displayed in the Log on to field of the credentials edit. In case you need to use the remote Machine's local account or the account from a domain that differs from the one provided by default, you should explicitly specify the Machine or the domain where the account is located in the user name. The Log on to field value is then changed to give you a clear understanding of which domain credentials are used.
The Log on to field displays, by default, the name of the domain where the network resource is located. If you explicitly specify a certain account, this field shows the domain or computer name for the account you are using. Thus, it always displays actual information about the domain to be used to establish connection.
To do the actions described above, you should input the value in the following format to the User Name field of the credentials pop-up edit:
<Username>@<FQDN> - for an explicit specification of an Active Directory domain account, where 'FQDN' is a fully qualified name of the domain.
<Domain name>\<User name> - for an explicit specification of a domain account, where 'Domain name' is a NetBIOS name of the domain to be used.
<Machine name>\<User name> - for an explicit specification of a remote Machine account.
Now you know how to provide the credentials to be used from a specific domain and can configure network credentials without any difficulties.
