What is the importance of 12/31/1969 to the IT world?

What is the importance of 12/31/1969 to the IT world?

• New Years Eve
• The first release of Windows 1.0 was shipped
• The Beginning of That 70s Show
• The beginning date of Unix and where it starts counting time from 

EXPLANATION

 Linux is following the tradition set by Unix of counting time in seconds since its official "birthday," -- called "epoch" in computing terms -- which is Jan. 1, 1970.

A more complete explanation can be found in this Wired News article. It explains that the early Unix engineers picked that date arbitrarily, because they needed to set a uniform date for the start of time, and New Year's Day, 1970, seemed most convenient.

 The Unix epoch is midnight on January 1, 1970. It's important to remember that this isn't Unix's "birthday" -- rough versions of the operating system were around in the 1960s. Instead, the date was programmed into the system sometime in the early '70s only because it was convenient to do so, according to Dennis Ritchie, one of the engineers who worked on Unix at Bell Labs at its inception.

How do you block a user from opening a folder, when that group has full permissions?

How do you block a user from opening a folder, when that group has full permissions?

• In AD uncheck Allow on the User in the group
• Explicit Deny User on the folder 
• Click Stop Permissions on the User in AD
• Create Exception on the folder for User 

 

EXPLANATION

Access Based Enumeration will be your best solution. That way even though the user account may be able to see a share, they can't see any of the contents. You could go a step further and create a Deny-SMB security group with that account as its sole member and then nest all of your other user level security groups in a group that is granted permissions to access shares.

Overall, more information is going to make the best possible route easier to recommend
