hacking the System Registry

Follow these steps:

Go to Start|Run type: regedit in the text box and click the OK button.
Then expand the
HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Explorer/RemoteComputer/NameSpace.

In the NameSpace folder you will find two entries.
One is "{2227A280-3AEA-1069-A2DE-08002B30309D}" which tells Explorer to show printers shared on the remote machine.
The other, "{D6277990-4C6A-11CF-8D87-00AA0060F5BF}," tells Explorer to show remote scheduled tasks.

This is the one that you should delete. This can be done by right-clicking the name of the key and selecting Delete.

If you have no use for viewing remote shared printers and are really only interested in shared files, consider deleting the printers key, "{2227A280-3AEA-1069-A2DE-08002B30309D}", as well. This will also boost your browsing speed.

Once you have deleted the key, you just need to restart and the changes will be in effect. Now your network computer browsing will be without needless delays.

Disabling unneeded protocols
Right-click the My Network Places icon on the desktop select Properties.
Or go to the Control Panel and click the Network Connections icon that is shown under the Classic view.

Next, right-click the network adapter with which you want to view the network protocols and select Properties.

This will bring up a list of the protocols installed as well as active on your adapter. Disabling a specific protocol Now that you have the list of installed and active protocols on your screen, you are ready to disable a protocol. To do so, just click the check box to remove the check. Then click the OK button and the protocol is no longer active on the network adapter.

Disable all protocols except for the TCP/IP protocol
