DNS requests are rejected when performing the query over TCP in Shared network mode in Windows virtual machine.
DNS requests over TCP in Shared network feature is supported only in Parallels Desktop for Business edition starting from Parallels Desktop 14.1.1 (45476) update build.
Such functionality is not supported in Parallels Desktop Home and Pro editions.
For Parallels Desktop Home and Pro editions please apply one of the following workarounds:
- Change the network type from Shared to Bridged by going to Windows virtual machine's configuration > Hardware > Network > Source.
- Assign DNS server manually in Windows network settings.
