Note: Before you configure the mappings, make sure that you have registered the vault-specific DNS (Domain Name System) names to DNS.

To specify mappings between incoming connections and M-Files vaults, add this registry configuration on the M-Files server computer.

Key HKEY_LOCAL_MACHINE\SOFTWARE\Motive\M-Files\<version>\Server\Common
Value name VaultDNSConfig
Value type Multi-String Value
Description The value specifies mappings between incoming connections and vaults.
Value

https://<DNS name for the vault 1>={<vault GUID for the vault 1>}

https://<DNS name for the vault 2>={<vault GUID for the vault 2>}

For example:

https://vault1.company.com={990827D8-8AF2-4A4E-B121-4C1A8AD8ECD0}

https://vault2.company.com={F565EDFE-939E-4507-B078-D06902888C98}

You can write one entry per row. To map many DNS names to a single vault, write each connection on a separate row. However, you cannot map the same DNS name to many vaults. If the list contains the same DNS name many times, only the topmost entry in the list is effective. For the changes to take effect, you must restart the M-Files Server service.
