Where it happened? On HP DL380!!!

This problem occurs when the following conditions are true:

• You enabled, disabled, or updated Hyper-V on a Hewlett-Packard (HP) server.

• The HP Network Configuration Utility was installed.

New SMB 2.0 allows higher speeds when transfering files between Windows server 2008 machines and Windows Vista machines.
On gigabit network we can see a drastical improvement in speed and network performance. SMB2.0 allows ACK packets to be sent only after 16 megabyte of data…

 SMB 2.0 as seen by Wireshark*

*Wireshark - excelent network analyzer

You can access harlink-ed files and Directory junction folders over the network… Even if files and folders are not shared (only “linked” to one of your shared folders …)

 Network accessability example

 Making SYMLINK without any parameters using MKLINK command

 Making SYMLINKD using MKLINK /D command

 Making HARDLINK using MKLINK /H command

 Making JUNCTION using MKLINK /J command

When you are using this command you should know that …

• When using without any parameters it makes symlink between two files … Files are accessible only localy on same machine.
• When using with /D parameter it creates symlinkd link between two folders … linked folder is accessible only localy.
• When using with /H parameter it creates hardlink between two files … This file is normaly accessible over the network and localy.
• When using with /J parameter it creates so called Directory junction that makes folder accessible using different name… It works localy and over the network.
  So now you are able to share a folder in which you can put Directory junction folders, that normaly are not shared…

I know you might think IRC is a bit “out”… But… On server irc.freenode.net you can find fantastic channels like:

#Windows - Windows related questions and discussions
#Windows-Server - Windows server realated stuff…
#Powershell - Powershell stuff…

If you want realy quick answers or maybe some advices to folow… Get an IRC client for example mIRC, get connected to server irc.freenode.org and join those channels…
