PC Tech Go: Basic Differences Between CAT5, CAT5E, CAT6, CAT6e, CAT6a Cables

What is the difference between 5,5e,6,6e,6a ethernet cables

What is the difference between 5,5e,6,6e,6a ethernet cables? One guess would be the speed, and that is correct. The speed of these cables is directly associated with the frequency they are able to carry and the distance the frequency can be maintained before it deteriorates or becomes weakened by outside interference called noise.

The number of twists, the thickness of the copper strands wrapped inside, the shielding, type of shielding, and the even the modular ends all play a role in how far a frequency can transmit and what ethernet speeds can be achieved.

Exchange 2003 Exchange 2010 Migration Coexistence NO Email Flow – PC Tech Support – Computer Desktop Software

This was an Exchange 2003 to Exchange 2010 migration. It is a swing migration as both servers will coexist during the migration process.

Having been involved with several Exchange 2003 to Exchange 2010 migrations with more to come, I’ve seen some interesting anomalies and differences in the installations and mail-flow issues.  One of which of course is at one of the installations there was no email between Exchange 2003 And Exchange 2010 Servers. After There was no email flow between the two email servers. A connector had to be created manually. The connector for this istallation was not created automatically to permit email to transcend from 2003 Exchange to Exchange 2010 and vice versa.

Exchange 2003 to Exchange 2010 Coexistence/Swing Migration

On another, the connector had been created during the installation but after several days to a week email stopped moving between the server versions. The connector had to be re-created using the Exchange Shell interface.

The connectors can be displayed using the Shell Command line:

Simply issue the command get-connectors and hit enter. This will display your connectors.

Display Only Current Year With PHP

Display Year With PHP

For many who maintain web sites, even on the personal level, the change of year requires updates to pages that have the year displayed on them . Web designers who have content managers running there sites already have this issue already covered in that the content manager is already running a server side script of PHP, ASP, Perl or other that updates the displayed year.

Many web site designers, for example, have to update the copyright year displayed on their own websites, and similarly on their client’s websites. Unfortunately, many end up doing the update manually and waste a lot of time with this tedious task, but many others use a better method, and it’s as simple as single line of PHP.

Copyright <? print(Date(“Y”)); ?>

Add this simple line of php code anywhere the year needs to be displayed and no longer will you have to manually edit the footer of your websites, or other pages, with each new year that passes.

Another use of the single line of code is in META tag that uses a year, such as the copyright content meta tag :

<META NAME=”copyright” CONTENT=”Copyright ©<? print(Date(“Y”)); ?>” />

The above works really well. I wish I had done this sooner as I have so many pages on one of my sites that I have the meta copyright tad included.

A useful way to provide remote support to computer users anywhere in the world. The usefulness of remote control support has inevitably brought about quick and customer satisfying computer desktop and server support. End-users and administrators of servers, cloud computing, virtual infrastructure and other services have all benefited from remote support and it’s instrumental in keeping users productive in all sorts of environments.

Moving a System Drive With Operating system From One Computer to Another and Reuse Product Key

From what I’ve seen when moving a hard drive from one computer to another is that the operating system has to be re-activated. Microsoft has built-in a certain number of hardware changes allowed before a de-activation of the OS occurs. This started with XP.

Transferring Hard Drive to New Computer

The target computer should be on the hardware compatibility list and it is recommended to have drivers for the new hardware specific to the operating system available before the drive is moved in case they are needed. That is, they are not built into the OS. It is highly recommended to download the NIC drivers at least for the target machine’s hardware before moving the drive from one computer to another. The reason for downloading and having the NIC drivers handy is that if you have at least the NIC drivers, you’ll be able to install them if needed and get your network card working. Which then in turn means you can then connect to the internet and download other drivers such as sound , video , etc..

Move the System C Drive Partition Activation

If the source computer’s operating system key does not use an OEM product key then you stand a very good chance that the hard-drive can be transplanted successfully into the new computer and activate the OS. If the key was a regular key for windows 7, XP, Vista, ie. a retail key, and it does not have the letters OEM in the key , then you can move it. Should there be a problem re-activating online then a call to Microsoft’s license clearing house is in order. It is a toll free call and most of the time problems can be solved by just using the automated system. Should an agent pick-up the call or you need to be transferred to an agent, you simply tell them you have moved the system drive from one computer to another. So, the largest determining factor is the type of product key that is in use on the source computer installation.

Share/Save/Bookmark

Support of servers and desktops can be at times actually interesting and enjoyable. The exception is of course when there’s is no remote control computer access through the web or even on the local LAN to the computers having a problem. Microsoft’s RDP is also useful for remote access but the only downside is the user cannot see the desktop screen at the same time.  Many times, I’ve encountered computers that have the windows firewall enabled. The firewall will block programs from connecting for remote access and control. Other programs for remote support initiate connections outbound from the computer. Outbound connections are mostly always more effective because windows firewall will notify the user to permit them to block the connection but after the application or utility has already made the connection out.

Backup Your Computer
Online Backups

Online backups have increased in popularity, selections, and reliability. what has also helped this backup strategy to work has also been the increased bandwidth from ISPs. Customers have better choices for internet access than they did years ago. It was almost impossible or took a very long time or was very unreliable to do backups online. Now it is very common and the support for better software has increased in features and reliability.
Just as the early years of computer remote control and support through the web especially web based remote support was a difficult task to do over dial-up, but it was done. Now with more internet speed, online remote support also has undergone a change with so many providers offering services throughout. Remote support software and online PC remote support software now are commonly used for remote access and control of computer desktops or servers for faster service by information technology departments and managed service providers.
Online backup software and solutions are increasingly popular because of the needed supporting infrastructure, namely internet access has improved. Smartphones nowadays have more bandwidth than many many companies had for their whole office.

When a reference is made to remote support software, it is often shought of that it is only for desktop support. Most often it includes remote control of a desktop desktop operating system to solve a user issue regarding and application or hardware configuration that includes installing or updating a driver.  What it also includes is remote control of server consoles even without an operating system or hard drives installed on the server.

Dell has such remote support access through just a browser in the form of technology called DRAC and iDRAC. This technology is a time saver and a tue helpful method to provide remote support over the web or on a LAN. Remote control access to the server is provided through a special board most often built-on the main board of the system but could be added in the form of a DRAC (Dell Remote Access Card). add-on card.

Basic Difference Between Exchange 2010 Enterprise and Exchange 2010 Standard

Exchange 2010 Enterprise or Standard

Microsoft Exchange Server 2010 is available in two editions;  Enterprise or Standard.  The basic and only real difference between the two Exchange editions is the number of databases you can have on a single host server installation instance. The database count includes either mailbox or public folder type.

  • Exchange Server 2010 Standard Edition can host up to 5 databases on a server.
  • Exchange Server 2010 Enterprise Edition can host up to 100 databases on a server.

That’s the basic and only real difference between the two versions.

Differences of Exchange 2010 Standard vs Enterprise: Windows Server 2008 Enterprise Required for DAG

Please Note:  For  Exchange 2010 Client Access Server (CAS) and Hub Transport Server (HT) Redundancy for providing High Availability and Failover in a Server, you will  need the  Enterprise version of the server OS.  To enable these HA and redundancy features, windows 2008 enterprise or windows 2008 R2 enterprise versions are required.

For small and medium sized businesses with 1 to several hundred user mailboxes, the standrad version of Exchange 2010 will suffice.

Microsoft decided starting with Vista to remove telnet from the defualt installation of the operating system. Perhaps it was for security or perhaps it was to save drive space 😉  Eeither way, telnet is not used that often or ever by the masses but for some who have to work on devises such as networking equipment it is extremely handy. It also comes in handy with network printers.

There are other tools out there like free putty and Secure CRT. The tools work fine but the fact it was removed after being part of the OS since the earliest of windows days can catch many by surprise and even knowing it is not there, I still get caught when I get a laptop of desktop upgrade and need to simply telnet into some hardware, it’s just not there.  Sure I have Secure CRT and putty is a downloadable exe.

Getting back onto your desktop, laptop or server is as simple however as adding it back in as a feature.

Set Default Program for Viewing images on XenApp and RDS 2008

via Set Default Program for Viewing images on XenApp and RDS 2008 – PC Tech Support – Computer Desktop Software.

One of the differences, and there are many, between windows 2003 server and windows 2008 server  (including windows 2008 R2) when using these operating systems for RDS (terminal services) with or without Citrix Xenapp is that file associations and default programs for opening or in the case of this post viewing files has changed.

The change is from an administrator having the ability to set a default program or file association once by logging to a server as an administrator and setting for example adobe pdf file be opened by reader or adobe acrobat while logged in as an administrator and that setting will apply to all users who connect to the server via terminal server RDP.RDS or through Citrix xenapp through a published app.

With windows 2008 server and windows 2008 R2, this setting is per user. That means each user can have a unique setting or different user groups can have different settings from each other.

Information Technology Support – Adventure (Rated PG): Disable Session Reliability in XenApp 6

Information Technology Support – Adventure (Rated PG): Disable Session Reliability in XenApp 6.

There are times when session reliability hasto be disabled in Xenapp. The name of this feature can be misleading in a sense that one can assume from the name that “they need it”. Yes, the words session reliability is one that conjures up images of with out it “my session won’t be relaible”. Oh, how that is not the case.

Session reliability in Citrix Xenapp world of things has to do with how long a disconnected session stays active and also what the end-user will experience during that short, or long, interuption. Session reliability in Citrix Xenapp means that when a session is disconnected, the user will still see the image pof their published applciation as it was before they were disconnected. However, they cannot interact with that session.

I needed to disable session relaibility because this setting was interfereing with my disconnected or idle sessions.
