When you use the getservbyname() function, an error is returned and the Services file located in %SystemRoot\System32\Drivers\Etc cannot be processed.
When C runtimes (CRTs) are linked dynamically (/MD - use Msvcrt.dll), the modules share one copy of the _fmode global variable. A change from its default _O_TEXT to _O_BINARY affects all modules, causing getservbyname to fail because it expects _O_TEXT.
When the CRT is linked statically, there are multiple copies of the CRT (and, therefore, multiple copies of _fmode) involved, meaning that changing the value of _fmode in the program changes the default mode for fopen throughout the .exe, but the default mode for any calls to fopen from the sockets DLL accesses the _fmode variable in CRT DLL whose value is _O_TEXT; therefore, no failure.
