These errors (53) indicate that the client fails to connect with a domain controller of the logon domain.

Please check the value of @LSERVER and verify that you can connect with this server from the client (using PING, for example). Doing so requires name resolution to work correctly. Depending on the environment, name resolution can only use DNS or may require WINS. If you only want to use DNS, you may need to add the domain-suffix of the logon domain to the DNS suffix list on the client.

Let me know if this helps.

Kind regards,
