I would suggest dynamically allocating the array instead, ie:

    #include <Iphlpapi.h>

    AnsiString mjgetnicinfo()
    {
        PIP_ADAPTER_INFO *Adapters = NULL;
        ULONG ulBufLen = 0;
        AnsiString retv;

        if( GetAdaptersInfo(NULL, &uiBufLen) == ERROR_BUFFER_OVERFLOW )
        {
            Adapters = (PIP_ADAPTER_INFO) LocalAlloc(LMEM_FIXED, uiBufLen);
            if( Adapters )
            {
                try
                {
                    if( GetAdaptersInfo(Adapters, &uiBufLen) ==
ERROR_SUCCESS )
                    {
                        PIP_ADAPTER_INFO pAdapter = Adapters;
                        do
                        {
                            AnsiString info;
                            info.sprintf("Name: %s\r\nDescription:
%s\r\nMAC: ",
                                pAdapter->AdapterName,
pAdapterInfo->Description);

                            for(unsigned int ii = 0; ii <
pAdapter->AddressLength; ++ii)
                                info += IntToHex(pAdapter->Address[ii], 2) +
":";
                            info += "\r\n";

                            retv += info;
                            pAdapter = pAdapter->Next;
                        }
                        while( pAdapter );
                    }
                    else
                        retv = "**Could not Obtain NIC Info";
                }
                __finally {
                    LocalFree(Adapters);
                }
            }
            else
                retv = "**Could not Allocate Memory for NIC Info";
        }
        else
            retv = "**Could not Calculate NIC Info";

        return retv;
    }
