Windows 7 networking security

Please include a screenshot or two showing your problem. If you have "one Windows machine left in the house" and its on that machine that you have problems accessing files on the other computers, it seems more likely that the problem actually is with the other computers on the network, i. I didn't say anything about setting up a HomeGroup nor do I recommend that anyone do that. In fact, in the "Answer" at the first link I provided, you'll see this emphasis added :.

Click on "Change advanced sharing settings". You do not want to be using Homegroup. As Cmdr Keene says, it's the password of an account on the machine where the files are.

The link I gave you suggested that you set up an account on the target machine with the same username and password as an account on the Windows machine, but that's not strictly required.

From your description, the files are not on your "one Windows machine left in the house. So you try to reach files on a hard drive that is literally connected to the computer and the computer asks for a password? That's not a network issue then, since by definition that is a local file. Please explain your problem more clearly and include some screenshots using the directions I provided earlier.

Logon failure: unknown user name or bad password. I have the same question 1. Report abuse. Wireless Networking Connecting to new wireless networks is something that has been made significantly easier in Windows 7. In the taskbar's notifications tray, there is a wireless signal icon just like in past Windows versions.

But clicking on it now brings up a list of available networks around you. You can connect to an unsecure network, or enter in your security code on a secure network and hit the Connect button.

Disconnecting is just as easy. HomeGroup HomeGroup is intended as an easy way for multiple computers on the same network to share their files, folders and smart content clusters known as libraries.

Properly implemented, HomeGroup could be a step closer to brainless networking, and it makes sense for families. If you access the HomeGroup tab in the Control Panel, you will be presented with the option in theory to create a new homegroup or join a currently existing homegroup. After creating a new homegroup, Windows asks you what libraries you want to share, and gives you a password for other computers on the network who want to join your homegroup.

When the new PCs jump on the network, they get prompted to join the homegroup, and are asked for the password. If these settings indicate that virus protection is not found, you must first install McAfee Anti-Virus software available free from the University's software download site. Then repeat steps above to confirm that the software was installed and is working properly.

You will see the statement McAfee VirusScan Enterprise reports that it is up to date and virus scanning is on if the software is operational. JavaScript is required to properly view this page.

Users who experience problems connecting to DirectAccess can use the appropriate troubleshooting wizard to identify and resolve problems. No matter how much network bandwidth an organization has, it is safe to assume it is not unlimited. As more users access the network, or more users connect to bandwidth-intensive data like streaming audio and video, the network bandwidth is nibbled away until it is gone, forcing the router to queue data, which in turn slows down network communications.

Even without maxing out the internal network capacity, this type of queuing often takes place where the internal network meets the external network. The internal network may be operating at 1GBps speeds, but the connection to the public Internet might be 10MBps.

Network packets from the internal network are queued by the router and transmitted on a first-come-first-serve basis as bandwidth becomes available on the external connection. Not all network destinations are created equal, though, or treated equally. Requests to an application server used to process orders or data being sent to a mission-critical database should take precedence over traffic destined for Google or Facebook, say.

Administrators can configure Quality of Service QoS to prioritize the traffic and ensure that the high-priority traffic gets preferential treatment. Windows will assign outgoing packets a DSCP Differentiated Services Code Point number that the router can use to determine the priority of the packets. As the network gets bogged down and packets are queued up, the default first-in-first-out functionality is overridden, and high-priority packets are sent out first.

The QoS functionality has been a part of previous versions of Windows, but it required that priority be assigned based on specific IP addresses and port numbers. However, multiple Web sites may use the same IP address, and one Web site may have multiple IP addresses, making QoS difficult to utilize in some instances.

Administrators can ensure that traffic intended for intranet applications or important Web sites gets processed ahead of lower-priority traffic see the last figure above without having to configure the precise IP address and port of the destination sites.
