May 15, 2018I have two independent systems/networks with 4 machines. All 4 use fixed IPV4 addresses. All 4 are on Window 10 Version 1803(17134.48). NetBIOS over TCP is not enabled on any of the machines. On one pair, I can ping to UPPERCASE, uppercase, and UpperCase is each direction and the names resolve. On the other pair full uppercase and full lowercase work for ping, but mixed case does not. Enabling NetBIOS over TCP does not help.

Just to say I've got the same problem on 1803. Only one machine exhibits the problem. Ping fails (no LLMNR request is broadcast as shown by Wireshark) if the hostname in the ping matches the destination machine hostname exactly in the same case. PING UPPERCASE fails with "could not find host" if the destination machine is set to UPPERCASE whilst all other case variations (lowercase and MiXed) succeed, If you change the destination machine computername to lowercase then PING lowercase fails with "could not find host", whilst all other case variations (UPPERCASE and MiXed) succeed.
In both scenarios PING UPPERCASE. <trailing Dot) and PING lowercase. succeed.
This is similar to a problem mentioned here.

but the solution of adding a "." appended DNS domain does not seem to resolve this problem.
Definitely something wonky in 1803.

ping lowercase with dot at the end, and ping all UPPERCASE works in here.

ping all lower case does not work for me, but ping all UPPERCASE does.
