Re:Speed Up Slow Network Connection - IT Support Forum

Tips to speed up LAN connection:

Disable Network Task Scheduler

Applying this tweak, you will disable networked computers search for scheduled tasks

Using Regedit:

HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows > CurrentVersion > Explorer > RemoteComputer > NameSpace

Once you found it, just delete the following key:

{D6277990-4C6A-11CF-8D87-00AA0060F5BF}

Raise the threshold level for the requested buffer

When dealing with a high-latency connection you need to increase the SizReqBuf value. We are talking here about a buffer, which is set by default to value of 4356 decimal. It seems that in most LAN conditions, the best value for the SixReqBuf would be 16384. Use this value on computers equipped with more than 256 MB Ram.

To change the value, first open the Registry Editor and locate

HKEY_LOCAL_MACHINE > System > CurrentControlSet > Services > LanmanWorkstation > Parameters and then create a DWORD value named SizReqBuf. Edit it and provide a decimal value of 16384.

Tweak the Network Redirector Buffers

By increasing the number of these buffers, you may get a higher transfer rate for the data that travels though the network. Open the Registry Editor navigate to this location:

HKEY_LOCAL_MACHINE > System > CurrentControlSet > Services > LanmanWorkstation > Parameters

Using the procedure explained in the previous tweak, add two new DWORD values:

MaxCmds and MaxThreads

Give both the same value between 0 and 255. It is recommended to choose the value of 64.

Eliminate the shares from My Network Places

Windows has an annoying behavior to place a shortcut in My Network Places for each remote folder accessed through the network. This creates an unpleasant delay when accessing the network. There are two ways to teach Windows not to do that anymore.

For Windows XP Home Edition

Locate HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > Policies > Explorer with Registry Editor and add a new DWORD value called NoRecentDocsNetHood setting its value to 1. The value 1 will disable the shares to be added in My Network Places.

For Windows XP Professional

Under this version of Windows, the process is easier. There is no need to edit the registry. Just go to Start > Run and type Gpedit.msc. It will open the Group Policy Editor. Using it, just go to User Configuration > Administrative Templates > Desktop and in the right panel, enable the option: "Do not add shares of recently opened documents to My Network Places".
