Restore Database without taking RDP
Assuming you have access and sufficient rights to the database on the SQL server via SSMS.
Create a shared folder on a different network server 192.I.Have.Access.  Grant the SQL engine and agent accounts read and write access to the shared folder.
You can take backups to the share (with write access) and you can restore backups from the share (with read access).  Direct access to folders on the server the SQL instance is installed on is not required.
BE-AWARE If someone besides you is responsible for SQL backups on the server.  Taking backups and/or restoring database can and probably will break the backup chain.  This will make disaster recovery for some period impossible, understand the implications to disaster recovery in your organization before making a one off backup or doing a restore.

If the only copy of the backup you want to restore is on the server in a folder you can not access; Congratulations you just learned why it is important copy backups to a safe location on a different server for disaster recovery.  I hope the lesson has not been overly expensive.
