Hello,

I am compiling a CPP code using Visual studion .net 2003. I get the
following error, despite having windldap.h and wldap32.dll in my include and
lib paths. Here is the error.

You need to add Wldap32.lib to the list of linked libraries in your
project settings. Alternatively, add:

#pragma comment( lib, "Wldap32.lib" )

to your source code (just after the #include for the header would be a
reasonable place) to use the automatic linking facility in VC++

That resolved the issue.

Thanks David
