The ping command is interpreting your hostname, 0x3c, as a hexadecimal number, and deciding that you want to ping 0.0.0.60. This isn't remotely valid, so ping generates an unknown error.
It's highly recommended that a Windows Server name starts with a letter, and you've found one of the strange bugs regarding why.
