Even if your Lync Server 2010 deployment is modest, you probably have components in your network that are the subject of books devoted to their security. Therefore, it is unlikely that this guide covers all aspects of security for all components and areas that are pertinent to your deployment. 

Use this Security Guide as a starting point to help secure and maintain a secure Lync Server 2007 deployment. This guide provides general guidelines, including best practices, for assessing and managing the most common security risks for Lync Server 2010. As new threats and solutions arise, you should supplement or replace outdated documents, solutions, and methods with new ones.

Symbolic Link – Create a link to a Special User Folder


mklink Creates a symbolic link

MKLINK [[/D] | [/H] | [/J]] Link Target
/D      Creates a directory symbolic link.  Default is a file symbolic link.
/H      Creates a hard link instead of a symbolic link.
/J      Creates a Directory Junction.

Link specifies the new symbolic link name.
Target  specifies the path (relative or absolute) that the new link refers to.

mklink /d Downloads c:\Users\<user>\Downloads


You can change the icon if you want, right mous click -> properties -> Cusctomize -> Change Icon…

Browse to Icons library :  C:\Windows\system32\imageres.dll and choose your icon.




Symbolic Links, Hard Links, Junction Points, and Shortcuts

There are 4 different types of links, each providing a slightly different function:

  • Shortcuts Shortcuts are files with a .lnk extension. If you double-click them within the Windows Explorer shell, Windows will open the target file. However, the file system treats .lnk files just like any other files. For example, opening a .lnk file from a command prompt does not open the target file.
  • Hard links Hard links create a new directory entry for an existing file, so a single file can appear in multiple folders (or in a single folder using multiple filenames). Hard links must all be on a single volume.
  • Junction points A lso known as soft links, junction points reference a folder using an absolute path. Windows automatically redirects requests for a junction point to the target folder. Junction points do not have to be on the same volume.
  • Symbolic links A pointer to a file or folder. Like junction points, symbolic links are almost always transparent to users. (Occasionally, a program might use an outdated application programming interface [AP I] that does not respect a symbolic link.) Symbolic links use relative paths rather than absolute paths.
