PDQ Deploy or PDQ Inventory reports "Failed to resolve hostname" when deploying or scanning to computers.
This is a native Windows error "Host not found" or "No such host is known", which means the hostname could not be resolved to an IP Address and all hostname resolution processes were used.
We use the default Microsoft TCP/IP hostname resolution order:
- Checks if the name queried is it's own.
- Checks if the name queried is in the host file.
- Checks the DNS client cache.
- Checks DNS servers.
- Checks LMNR.
- Checks NetBIOS.
