I am trying to install an application which uses the API GetIPAddrfromTable stack. When I start up the application, I get the error “Procedure entry point not found in IPHLPAPI.dll”

I noticed that the dll file was quite old, so I tried replacing it, but Windows server 2008 doesn’t let anyone copy any files to the system32 folder, even if you are administrator.

    There is no such function, GetIpAddrTable() is the closest match. Do not replace DLLs in c:\windows\system32, this can greatly destabilize Windows, assuming it would let you. Iphlpapi.dll is a native DLL. It cannot be registered with Regsvr32, it is not a COM component. Nor can you use Regasm.exe, it is not a .NET assembly.

    I have to guess that your [DllImport] declaration is simply wrong. Consider using this one.
