Understanding Windows NTFS Permissions

Even though Windows permissions have been around for a long time, I still run into seasoned network administrators that aren’t aware of the new changes that came with Windows 2000 so long ago. When Microsoft released Windows 2000, they released a new version of NTFS, which was versioned 5. The new NTFS permissions were essentially the same logical control as the older version that was available in Windows NT, however, there were some radical and essential changes that occurred to control how the permissions were inherited and configured for each file and folder. Since NTFS permissions are available on every file, folder, Registry key, printer, and Active Directory object, it is important to understand the new methods and features that are available once you have Windows 2000, Windows XP, or Windows 2003 Server installed to control resources.

Standard Permissions

Standard permissions are those permissions that control a broad range of detailed permissions. The most popular and infamous standard permission is Full Control. This is what everyone wants, but in reality very few should get. Full Control allows the user that is granted this suite of permissions to do virtually anything to the object the permissions are associated with. The other standard permissions include the following:

Files:

Modify
Read & Execute
Read
Write

Folders have the same standard permissions as files, except there is one additional standard permission “List Folder Contents.”

How to fix slow LAN transfer speed of files in Windows 7

Recently I had to solve a problem of a very slow transfer of files between two computers on a LAN network using Ethernet cable. Both machines had Windows 7 x64 installed and the transfer speed was ridiculously slow at 10-15kb/s. Using Task Manager under Networking tab, Network Utilization was showing only around 0.25% for Local Area Connection.

I looked around the web for solutions and found quite a few suggestions how to tackle this problem. Those that I tried and the one that finally solved my problem are discussed here.

Turning off “Remote Differential Compression”

One of the first suggestions that I came across was to turn off this Windows Feature in Windows 7.

Which is better, a wired or wireless network?

Which is better? That depends on your situation and your priorities.

Wired Home Networking
A wired home network uses Ethernet cable to connect the computers to the network router. Wired home networks are less expensive, faster, and more secure than wireless networks. However, the same Ethernet cable that provides these advantages, is also its biggest disadvantage. All computers on a wired network must be connected by Ethernet cable. Running Ethernet cables between rooms or floors can be a significant challenge.

IPv6

IPv6 is the next generation Internet Protocol (IP) address standard that will supplement and eventually replace IPv4, the protocol most Internet services use today.

Why It Matters
An IP address is basically a postal address for each and every Internet-connected device. Without one, websites would not know where to send the information each time you perform a search or try to access a website. However, the world officially ran out of the 4.3 billion available IPv4 addresses in February 2011 .

THE RIGHTS, EXPECTATIONS AND RESPONSIBILITIES OF THE NETWORK MANAGER

The network manager (and his team) is responsible for maintaining the network. In order to carry out this task the network manager often has an elevated level of access privileges. The network manager should be able to expect these access rights as standard and would naturally expect a degree of autonomy from the company managers. Balancing these, are a set of responsibilities and duties that must be performed in order to maintain the position given. These rights, expectations and responsibilities will now be examined in more detail.

 

RIGHTS

Network managers have a large and far reaching set of rights and privileges in order to help them administer to the network that which must be administered. A network manager may not necessarily directly exorcise those rights but will likely delegate certain roles to his team of administrators and technicians. Ultimately it must be recognised of all the administrators and technicians that they do not operate under their own authority and direction but under the authority and direction of the network manager and is the network manager alone who willanswer for everything that they do, say or fail to do.

As will be made apparent in the section entitled “Responsibilities” the network manager is answerable for the network and activities carried out thereon. As such, the network manager must have the right to set out policies of acceptable use, grant and revoke rights of access to different areas of the network
