  • Windows 7-Add/Remove Sites in IE Security Zones

    How to Add or Remove Sites in Internet Explorer Security Zones
    Information
    Zone security is a system that enables you to divide online content into categories, or zones. You can add or remove websites from the zones, depending on your level of trust in a website.

    This article will show you how to add or remove website URL addresses in the Internet, Local Intranet, Trusted sites, and Restricted sites Internet Explorer security zones.
    Note
    Internet zone
    You will not be able to add or remove sites in the “Internet” zone. The Internet zone includes all sites on the internet that are not in the Trusted sites or Restricted sites zones.
    Local intranet zone
    The Local intranet zone includes all sites inside an organization’s firewall (for computers connected to a local network). By default, the Local Intranet zone contains all network connections that were established by using a Universal Naming Convention (UNC) path, and Web sites that bypass the proxy server or have names that do not include periods (for example, http://local), as long as they are not assigned to either the Restricted Sites or Trusted Sites zone. The default security level for the Local Intranet zone is set to Medium-low. Be aware that when you access a local area network (LAN) or an intranet share, or an intranet Web site by using an Internet Protocol (IP) address or by using a fully qualified domain name (FQDN), the share or Web site is identified as being in the Internet zone instead of in the Local intranet zone. For more information about this issue, click the following article number to view the article in the Microsoft Knowledge Base:
    303650 Intranet site is identified as an Internet site when you use an FQDN or an IP address
    Trusted sites zone
    The Trusted sites zone can include all Internet sites that you know are trusted. For example, the Trusted sites zone might contain websites that are on your organization’s intranet or that come from established companies in whom you have confidence. When you add a website to the Trusted Sites zone, you believe that files you download or that you run from the website will not damage your computer or data. By default, there are no websites that are assigned to the Trusted Sites zone, and the security level is set to Medium.
    Restricted sites zone
    The Restricted sites zone can include all sites that you do not trust. When you add a website to the Restricted Sites zone, you believe that files that you download or run from the website may damage your computer or your data. By default, there are no websites that are assigned to the Restricted Sites zone, and the security level is set to High.
    Here’s How:
    1. Open the Control Panel (Classic View (Vista) or Icons View (Windows 7)).
    A) Click on the Internet Options icon.
    B) Go to step 3.
    OR
    2. Open Internet Explorer.
    A) Click on Tools (Menu bar) or gear icon (in IE9), click on Internet Options, and click on the Security tab.
    3. For the Internet Zone
    A) You will not be able to add or remove sites in the Internet zone since it automatically includes all sites on the internet that are not in the Trusted sites or Restricted sites zones.
    B) Go to step 7.
    4. To Add or Remove Sites for the Local intranet Zone
    A) Select Local intranet, and click on the Sites button. (see screenshot below)
    B) Check what settings (automatically detect or specifics) to define which websites are included in the local intranet zone, then click on the Advanced button. (see screenshots below)
    NOTE:
    The default setting is Automatically detect intranet network.
    Include all local (intranet) sites not listed in other zones. Intranet sites, such as http://local, have names that do not include dots. In contrast, a site name that does contain dots, such as Microsoft Corporation, is not local. This site would be assigned to the Internet zone. The intranet site name rule applies to File URLs as well as HTTP URLs.
    Include all sites that bypass the proxy server. Typical intranet configurations use a proxy server to gain access to the Internet but have a direct connection to intranet servers. The setting uses this kind of configuration information to distinguish intranet from Internet content. If your proxy server is configured otherwise, you should clear this check box and then use other means to designate the Local intranet zone membership. For systems without a proxy server, this setting has no effect.
    Include all network paths (UNCs). Network paths (for example, \\servername\sharename\file.txt) are typically used for local network content that should be included in the Local intranet zone. If some of your network paths should not be in the Local intranet zone, clear this check box and then use other means to designate the Local intranet zone membership. In certain Common Internet File System (CIFS) configurations, for example, it is possible for a network path to reference Internet content.
    C) To Add a Website to Internet Zone
    Check (only add https: websites) or uncheck (add any website) the Require server verification (https for all sites in the zone option for what you want websites you want added.
    Type in the website address and click on Add. (see screenshot below)
    D) To Remove a Website from Internet Zone
    Under Websites, select a added website and click on Remove. Repeat to remove additional websites. (see screenshot below)
    E) When finished, click on Close. (see screenshots below steps 4C and 4D)
    F) Click on OK. (see screenshots under step 4B)
    G) Go to step 7.
    5. To Add or Remove Sites for the Trusted Sites Zone
    A) Select Trusted Sites, and click on the Sites button. (see screenshot below)
    B) To Add a Website to Trusted Sites Zone
    Check (only add https: websites) or uncheck (add any website) the Require server verification (https: ) for all sites in the zone option for what you want websites you want added.
    Type in the website address and click on Add. Repeat to add additional websites. (see screenshot below)
    C) To Remove a Website from Trusted Sites Zone
    Under Websites, select a added website and click on Remove. Repeat to remove additional websites. (see screenshot below)
    E) When finished, click on Close. (see screenshots below steps 5B and 5C)
    F) Go to step 7.
    6. To Add or Remove Sites for the Restricted Sites Zone
    A) Select Restricted Sites, and click on the Sites button. (see screenshot below)
    B) To Add a Website to Restricted Sites Zone
    Type in the website address and click on Add. Repeat to add additional websites. (see screenshot below)
    C) To Remove a Website from Restricted Sites Zone
    Under Websites, select a added website and click on Remove. Repeat to remove additional websites. (see screenshot below)
    D) When finished, click on Close. (see screenshots below steps 6B and 6C)
    7. Do steps 4, 5, or 6 above if there are any other security zone that you would like to add or remove sites from.
    8. When finished, click on OK. (see screenshot below steps 3A, 4A, 5A, or 6A)

  • Enable or Disable Write-Caching- Windows 7

    How to Enable or Disable Write-Caching for a Storage Device in Windows 7
    Information
    Write caching in a connected storage device refers to the use of high-speed volatile memory to collect write commands sent to data storage devices and cache them until the slower storage media (either physical hard disks or low cost flash memory) can accommodate them. Most devices that use write caching require that power be supplied continuously.

    This article will show you how to enable write caching to have better performance for a storage device, or disable write caching for quick removal of a storage device without having to use Safely Remove Hardware.
    Tip
    If high data transfer performance is your main concern, you should enable both of these settings in OPTION TWO below:
    In the Removal Policy section, select the Better Performance option.
    In the Write-caching policy section, select Enable write caching on the device (if the system hardware and storage device support these features).
    Warning
    You must be logged into a administrator account to be able to do this tutorial.
    OPTION ONE
    Disable Write Caching for Quick Removal
    Note
    This option is usually the best choice for storage devices that you are likely to remove from the system frequently, such as USB flash drives, SD, MMC, Compact Flash, or similar memory cards, and other similar externally attached storage devices.
    When you select the Quick Removal option, Windows 7 manages commands sent to the device using a method called write-through caching. In write-through caching, the device operates on write commands as if there were no cache. The cache may still provide a small performance benefit, but the emphasis is on treating the data as safely as possible by getting the commands to the storage device. The main benefit is that you can remove the storage device from the system quickly without risking data loss. For example, if a flash drive were to be accidentally pulled out of its port, the data being written to it is much less likely to be lost.
    1. Open the Control Panel (All Items view), and click on the Device Manager icon.
    2. In Device Manger, double click on Disk drives to expand it, then double click on the listed storage device that you want to disable write caching for. (See screenshot below)

    3. Click on the Polices tab. Under the upper Removal policy section, select (dot) Quick removal, or check the Turn off Windows write-cache buffer flushing on the device box, and click on OK. (See screenshot below)

    4. Click on Yes to restart the computer to apply. (See screenshot below)
    WARNING:
    This will restart the computer immediately. You should save and close anything else that you are working on first.
     
    OPTION TWO
    Enable Write Caching for Better Performance
    Note
    This option is usually the best choice for storage devices that must provide the highest possible performance and that you intend to not remove from the system frequently, such as internal hard disk drives. If you choose this option and the device is disconnected from the system before all of the data is written to it (such as if you remove a USB flash drive), you could lose data. When using this option for a storage device (ex: USB flash drive), you must use Safely Remove Hardware to disconnect the device safely to prevent possible data loss.
    When you select the Better Performance option, Windows 7 uses a method known as write-back caching. In this method, the storage device itself is allowed to determine whether using the high-speed cache will save time completing the write commands. If it will, the device signals to the computer that the data has been stored successfully even though the data may not actually be present in the storage device yet (such as the hard disk or flash memory). This method markedly increases the throughput of storage operations, which are often a major bottleneck for system performance overall. However, if the power supplied to the device (ex: external hard drive) fails for any reason, any data still in the cache (that the computer system believes is safely stored) could be lost.
    By default, Windows 7 uses cache flushing. This means that the system will periodically instruct the storage device to write all data waiting in the cache to the storage device. When you select Enable write caching on this device, you turn can turn off these periodic commands to transfer the data. Not all devices support all of these features.
    1. Open the Control Panel (All Items view), and click on the Device Manager icon.
    2. In Device Manger, double click on Disk drives to expand it, then double click on the listed storage device that you want to enable write caching for. (See screenshot below)

    3. Click on the Polices tab. Under the upper Removal policy section, select (dot) Better performance. (See screenshots below)
    NOTE:  
    By default, Enable write caching on the device is also checked. If not, then check it as well.

    4. To Turn Off Windows Write-cache Buffer Flushing on the Device –
    WARNING:
    To Prevent data loss. Do not check this option unless the storage device has a separate power supply that allows the device to flush it’s buffer in case of a power failure.
    A) Select (check) the Turn off Windows write-cache buffer flushing on the device box. (See screenshots above)
    5. Click on OK. (See screenshot below step 3)
    6. Click on Yes to restart the computer to apply. (See screenshot below)
    WARNING:
    This will restart the computer immediately. You should save and close anything else that you are working on first.

  • Enable Remote Desktop Connection- Windows 7

    Enabling Remote Desktop Connections in Windows 7
    Information
    Windows Remote Desktop Connection allows you to connect to a Windows-based computer via the Internet or a network. When you’re connected via the Remote Desktop Connection, you can see the host computer’s desktop and access its files and folders as if you were sitting in front of the computer. 
    This is useful for both systems administrators and technical support teams as well as end users, who may want to access their work computers from home or vice-versa.

    In this tutorial, you’ll learn how to enable Remote Desktop Connections on your Windows-based computer so that it can be controlled remotely.
    Here’s How
    Enabling Remote Desktop Connections on your Windows Computer
    1.       To enable Remote Desktop Connections, click the Start button, right-click on Computer and choose Properties.
    2.       In the System Properties window, click Remote settings in the left panel.
    3.       This will open the Remote tab of the System Properties window. Here, you have three options to choose from under Remote Desktop:
    4.       Don’t allow connections to this computer – This option will prevent users from connecting to your computer using Remote Desktop Connection or RemoteApp. (RemoteApp connections are connections where the client only connects to a single application.)
    5.       Allow connections from computers running any version of Remote Desktop – This will allow users running any version of RemoteApp or Remote Desktop Connection to connect to your computer. Use this if you’re not sure which version of Remote Desktop the client will be using, or if they are using a third-party Remote Desktop Connection application. (For example, Ubuntu clients will likely require the second option.)
    6.       Allow connections only from computers running Remote Desktop with Network Level Authentication – This restricts Remote Desktop Connections to those running versions of Remote Desktop that have Network Level Authentication. Network Level Authentication was introduced in Remote Desktop Client 6.0. If the client computer is running Windows 7 or they’ve recently downloaded the Remote Desktop Connection client, use this option, as it’s more secure.
    7.       At this point, you can click OK and clients will be able to log in to your computer via Remote Desktop Connection using the login credentials for administrator level users. However, you probably won’t want to give out your administrator credentials to tech support people, network admins and others. So, it’s a good idea to set up a separate standard level user account for Remote Desktop Connections.
    8.       First, create a user account following the instructions in our previous tutorial: How to Create or Delete User Accounts.
    9.       Next, return to the Remote tab in System Properties and click Select Users. This opens the Remote Desktop Users window.
    10.    Type the user account name in the box in the next window and click Check Names. Windows will make sure that a user account with that name exists and add the location in front of it. For example, in these screenshots, I’m going to allow users to connect to my computer via Remote Desktop Connection using credentials for a standard user account called 7Tutorials. After clicking Check Names, Windows automatically adds the location where the user account is.
    11.    When you’re done, click OK. Now, users will be able to connect via Remote Desktop Connection to your computer with the login credentials for the user you selected.
