Microsoft Office 2007 Enterprise Edition

Microsoft Office 2007 Enterprise Edition was a comprehensive suite of productivity software that included several applications to help users create, manage, and share documents, spreadsheets, presentations, and more. Some of the notable features and specialties of Microsoft Office 2007 Enterprise Edition included:

Ribbon Interface: Office 2007 introduced the Ribbon interface, which replaced the traditional menu and toolbar system. The Ribbon grouped commands and features into contextual tabs, making it easier for users to find and use various functions.
XML-Based Formats: Office 2007 introduced new default file formats for documents, spreadsheets, and presentations. These formats were based on XML (eXtensible Markup Language) and had file extensions such as ".docx" for Word documents, ".xlsx" for Excel spreadsheets, and ".pptx" for PowerPoint presentations. These formats offered improved data recovery and reduced file sizes.
Document Themes and Templates: Office 2007 included a range of pre-designed document themes and templates, making it easier for users to create professional-looking documents, presentations, and spreadsheets with consistent formatting.
Enhanced Collaboration: Office 2007 introduced improved collaboration features, such as the ability to save documents directly to Microsoft SharePoint Server, which allowed multiple users to work on the same document simultaneously and track changes.
Office Online Integration: The Enterprise Edition included integration with Microsoft Office Online (previously known as Office Web Apps). This allowed users to view and edit documents stored in Windows Live SkyDrive (now OneDrive) directly from within the Office applications.
Microsoft Groove (Now SharePoint Workspace): The Enterprise Edition included Microsoft Groove, a collaboration and communication tool that allowed users to create shared workspaces for collaborating on documents and projects, even when offline. Groove has since been renamed SharePoint Workspace.
Content Management: The Enterprise Edition included tools for managing content and documents, such as Document Information Panels and Document Inspector, which helped users manage document properties and remove sensitive information before sharing documents.
Improved Data Analysis: Microsoft Excel in Office 2007 introduced enhanced data analysis and visualization tools, including PivotTables, PivotCharts, and Conditional Formatting, allowing users to analyze and present data more effectively.
Enhanced Security: Office 2007 Enterprise Edition included security features like Information Rights Management (IRM), which allowed users to apply restrictions to documents and emails to prevent unauthorized access and distribution.
Outlook Integration: Microsoft Outlook received several updates, including an improved user interface, better integration with other Office applications, and enhanced search and filtering capabilities.

It's important to note that Microsoft Office 2007 has reached its end of support, and Microsoft recommends upgrading to a more recent version of Office to ensure security updates and access to the latest features.

Network Cabling Technics

How many wires are inside an Ethernet cable? Do all of them work?

There are 8 total wires inside a modern Ethernet twisted-pair cable with an 8P8C connector, braided into 4 pairs. All of the 8 wires can be put to work for 1000Base-T/GigE signaling at rates up to 1 Gbps, but only 4 are needed for either 10Base-T signaling at rates up to 10 Mbps or 100Base-T/Fast-E signaling at rates up to 100 Mbps. Additionally, the blue wires alone can be used on recrimped Cat5e cables for telephony, changing the connector from 8P8C to RJ11.

Using 100Base-T or lower frees up wires for other uses. In the 802.11af Power over Ethernet standard, wires 4 and 5 are ground wires, and wires 7 and 8 are live power wires. Ethernet cables can also be used with HDMI-over-Ethernet adapters as an in-place cabling method when lower signaling rates are acceptable. You could even peel off 2 pairs (for 4 total wires) to support 100Base-T Ethernet and 2 separate phone lines.

Which two wires on the ethernet cable can be used for wireless transmision?

There are no “wireless” wires in an Ethernet cable, that is to say there are no wires in an Ethernet cable specifically used for wireless transmission

Ethernet cable, like CAT5e or CAT6a Cable, has 4 twisted pairs of 2 wires each, resulting in 8 total wires

Each pair has a distinctive color, Blue, Orange, Green and Brown, one of the two wires in the pair will typically have a white stripe or band (or on some cable will have a white cable with a colored band selecting it’s matched pair), the other wire in the pair will be a solid color

So what does each wire actually do?

Well, in each pair, one wire is typically a positive and the other is negative (aka Tip and Ring)

So now what does each pair actually do?

Well, this depends on the network

On 10/100 based networks (10Mb/100Mb), only the Orange and Green pairs are used, the Blue and Brown pairs go unused, in some creative wiring, you may see the Blue and Brown pair used for another Ethernet connection, and in some cases used for phone wiring alongside the Ethernet

Sometimes either the Blue or Brown pair is used to deliver DC electrical current, this is known as PoE or Power over Ethernet

In 1000Mb Ethernet, aka 1Gb or Gigabit Ethernet, all 4 pairs (8 wires) are used for data transfer, it is still compatible with PoE like 10/100 networks are, but there is also data being sent down the line that the DC current is traveling down

This is all related to a wired network

Okay, so if this is all for a wired network, how to you send a wireless network through Ethernet?

Well, simply put, you don’t, you add wireless networking to a wired network, it’s converted from a wired signal over the Ethernet cable to a wireless signal over the air and vice versa

So how is this done?

With a device called a WAP or Wireless Access Point, this device has an Ethernet port on the back and connects to a wired network like any other device (like a computer with an Ethernet port), a wireless device (like say a laptop) communicates to the WAP and the WAP communicates to the Ethernet network like any other wired device

No WAP, no Wi-Fi

Multiple RDP Sessions

Multiple RDP Sessions.docx

Multiple RDP Sessions

By default, Windows 2012 servers allow a single Remote Desktop session. If only one session is available and we take over another person's live session, we may choose to enable multiple RDP sessions. This article describes the process for enabling and disabling multiple sessions.

Enable Multiple RDP Sessions

1. Log into the server using Remote Desktop.

2. Open the start screen (press the Windows key) and type gpedit.msc and open it:

SUMMARY

If you already use Remote Desktop Services with MyWorkspace, you might have noticed, that you can only have one RemoteApp open at a time. This is because by default, Windows Server 2012 allows only a single Remote Desktop session for each user.

This article describes how to enable (and disable) multiple sessions. This way you can use multiple RemoteApps in different tabs at the same time.

GOAL

After completing this how-to you will have your Remote Desktop Services configured to allow multiple sessions. Hence allowing your users to use multiple RemoteApps in MyWorkspace at the same time.

Enable Multiple RDP Sessions

1. Log into the server, where the Remote Desktop Services are installed.

2. Open the start screen (press the Windows key) and type gpedit.msc and open it.

3. Go to Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Connections.

4. Set Restrict Remote Desktop Services user to a single Remote Desktop Services session to Disabled.

5. Double click Limit number of connections and set the RD Maximum Connections allowed to 999999.

Disable Multiple RDP Sessions

1. Log into the server, where the Remote Desktop Services are installed.

2. Open the start screen (press the Windows key) and type gpedit.msc and open it.

3. Go to Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Connections.

4. Set Restrict Remote Desktop Services user to a single Remote Desktop Services session to Enabled.
