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.

How To Become MCITP Certified Server Administrator

GUID Partition Table

GUID Partition Table (GPT) is a standard for the layout of the partition table on a physical hard disk, using globally unique identifiers (GUID). Although it forms a part of the Unified Extensible Firmware Interface (UEFI) standard (Unified EFI Forum proposed replacement for the PC BIOS), it is also used on some BIOSsystems because of the limitations of MBR partition tables, which use 32 bits for storing logical block addresses and size information.

As of 2010, most current operating systems support GPT. Some, including OS X and Microsoft Windows, only support booting from GPT partitions on systems with EFI firmware, but FreeBSD and most Linux distributions can boot from GPT partitions on systems with either legacy BIOS firmware interface or EFI.

The widespread MBR partitioning scheme, dating from the early 1980s, imposed limitations which affect the use of modern hardware. One of the main limitations is the usage of 32 bits for storing logical block addresses and size information.

For hard disks with 512-byte sectors, the MBR partition table entries allow up to a maximum of 2 TiB(232×512 Bytes).[1] GPT allocates 64 bits for logical block addresses and therefore allows a maximum partition size of 264−1 sectors. For disks with 512-byte sectors, that would be 9.4 ZB (9.4 × 1021 bytes) or 8 ZiB−512 bytes (9,444,732,965,739,290,426,880 bytes or 18,446,744,073,709,551,615 (264−1) sectors × 512 (29) bytes per sector).[1][2]

Intel therefore developed a new partition-table format in the late 1990s as part of what eventually becameUEFI. The GPT as of 2010 forms a subset of the UEFI specification.[3]

Windows 7 tips | Show the Windows Desktop with a new shortcut

If you’re anything like us, once you’ve installed a new operating system or bought a new PC, you start out organizing files and documents with the best of intentions. But before long your Windows Desktop becomes your de facto filing cabinet, peppered with shortcuts, frequently used spreadsheets, random photos, and abandoned detritus. The easy way to access that debris field to find something—the Windows key + D combination, which minimizes all Windows for a clear view of the desktop—is a helper that most of us know.

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
