RPC_NT_INVALID_NAME_SYNTAX
The supplied RPC name syntax is invalid
RPC name-service APIs require a name syntax that tells the runtime how to interpret the entry name. This status means the syntax selector or string form is not valid before lookup can even resolve an entry.
Check whether the code mixes default syntax, explicit syntax constants, and provider-specific names. The problem is not that the server is down; the name cannot be parsed correctly.
What to inspect
- Log the name syntax constant and entry name string.
- Use the same syntax when exporting and importing name-service entries.
- Avoid passing a display name or endpoint string where an RPC name-service entry is required.
