What you should know about winrnr.dll LDAP RnR Provider DLL
winrnr.dll is not part of Windows, but it is important nonetheless. The file winrnr.dll is found in the C:\Windows\System32 directory.

This so-called dynamic link library (DLL) contains all the functions that have been transferred to a separate file. These transferred functions are available not only to this particular program, but can also be used by other applications. The program executes in the background, and can only be terminated using Windows Task Manager. It also can also affect other applications by changing their properties. Such manipulation can cause an application to do things other than what it is intended to do. It was developed by a so-called third party provider - and not by Microsoft. For this service - unlike Windows' own system services - there is no good description available. The original file by Microsoft is digitally signed. So please check the file on your computer. winrnr.dll appears to be a file that was compressed by an EXE-Packer. This technique is often used by trojans to keep the file size small and also hamper debugging efforts. However, this in itself is not sufficient reason to presume malicious intent, since even well-intentioned, professional software producers take advantage of compressed files. For this reason, 40% of all experts consider this file to be a possible threat. The probability that it can cause harm is high.
If you see this file on your hard drive or in Windows Task Manager, please make sure that it is not a malicious variant. It's a fact that many trojans try to cloak their true identity by calling themselves winrnr.dll. With the above information or by using tools like Security Task Manager you can determine if, in your case, the file is an undesirable variant.
