If you rename the computer hosting the Autodesk Vault server, the computer name must also be updated in the Autodesk Vault server. The computer name can be changed in the vault server either before or after the actual computer name is changed. In a multi-site environment, the name of the computer hosting the Autodesk Vault server is the name of the site.
