Error 800: Unable to establish connection

When computers both internally and remotely try to VPN into my server that is running Windows Server 2003 R2 Enterprise Edition, they receive VPN Error 800: The remote connection was not made because the attempted VPN tunnels failed.

Your windows Server 2003 R2 use to work 100% without any technical problems, and you have not changed any configuration settings on the server.

Troubleshooting:

We noted that only 3 VPN clients were able to establish the VPN connection, the fourth connection was encountering the VPN Error 800:

Resolution:

We needed to increase the number of available ports for the client remote access / VPN users, by going to open the Routing and Remote Access console.  It is under the Administrative Tools menu > Routing and Remote Access, expand the RAS – right click on ports and then select Properties.

Select the WAN Miniport (PPTP) entry and then select the Configure button at the bottom.

You can then change the number of ports to the maximum number of VPN users you will expect.  For example in our environment we changed it to 20.

OK,  OK again – Restart the Server.

Why do you need Windows Server 2012?

The Microsoft Windows Server platform has been powering businesses both large and small for over a decade. Building on this substantial legacy, Microsoft now offers Windows Server 2012 – a groundbreaking server solution that provides hundreds of new features and enhancements. Windows Server 2012 also provides what is quite possibly the most advanced set of virtualization capabilities available in one integrated package. Now is the perfect time for you to engage Magwinya Wired to help your company to upgrade to Windows Server 2012, and to find out for yourself why the early adopters have called it “jaw dropping.”

*Getting Started with Virtualisation

The benefits of virtualization can’t be argued with – the cost savings, the flexibility to add servers, the options for disaster recovery. But virtualization has to be done right in order to deliver value to the business, preferably using tools we understand and trust. Windows Server 2012 gives us those tools, with comprehensive virtualization capabilities that are bundled right into the server operating system. With Windows Server 2012, we’ll have everything we need to start building a world-class virtualization infrastructure that will serve us for years to come.

*Getting More Bang for Your Money.

The perks of having virtualization in your infrastructure are clear, from giving you more value from your hardware to increasing your business flexibility. But virtualization comes at a price, and with Windows Server 2012, it’s a price that’s more affordable than ever. Right out of the box, Windows Server 2012 Standard Edition includes licenses for two virtual machines – at no extra cost. Beyond that, we’re charged as you add virtual machines and are not charged per processor, the way competitor products are sold. It’s a pricing model that will give you more bang for your virtualization money.

*Making The Most Of Your Storage Resources

Windows Server 2012 provides powerful storage virtualization capabilities that can improve storage performance while giving you the scalability to handle rapid data growth. This feature, called Storage Spaces, allows you to combine all of your storage resources – regardless of size or vendor – into one easy-to-manage pool. Virtualizing your storage in this way will help you reduce IT costs by making the best possible use of your existing storage investments.

*Boosting Application Uptime

With Windows Server 2012, Microsoft gives company like yours access to business continuity and disaster recovery technologies that were previously available only to large enterprises. The virtualization software that comes with Windows Server 2012 includes a robust replication feature that captures changes to your virtual machines every five minutes. It works quietly in the background to ensure that if anything goes wrong with a virtual machine, you have a copy you can restore immediately. Windows Server 2012 also provides “live migration” features, which means that virtual machines and storage can be moved and maintained without taking them offline, helping to ensure application uptime.

*Enabling More Efficient Server Management

In companies like yours, it’s imperative that you get the most out of your IT resources. That includes human resources as well. Windows Server 2012 is designed to help you get the most out of IT by making server management easier and more efficient than ever before. For example, it provides features that allow you to manage multiple servers remotely, providing a full spectrum of management control from a single interface. Other new features simplify time-intensive tasks such as server configuration and deployment, freeing up your resources to handle other business and IT projects.

There you have it!

With this release, Microsoft is providing you a giant toolbox of technologies to make the most of your server resources – both physical and virtual. Built on a long legacy of stability and support, Windows Server 2012 is a platform designed to handle complexities and change, and it’s one you can count on to carry our business forward.

Problem Updating WordPress, Themes and Plugins

You are trying to Update WordPress CMS, Themes and Plugins to the latest Version on Ubuntu 13.04 Web Server, and you encounter an error messages similar to the following:

  1. To perform the requested action, WordPress needs to access your web server. Please enter your FTP credentials to proceed. If you do not remember your credentials, you should contact your web host.
  2. Could not create directory. wp-content/upgrade/xxx.tmp
  3. removing the old version of the plugin… could not remove the old plugin. plugin update failed.
  4. an error occurred while updating twenty eleven: could not remove the old theme..
  5. The list goes on …etc

Resolution that worked for me:

You need to set the proper filesystem privileges:

Access your Ubuntu 13.04 Web server through SSH and then run this command:

#chown -R www-data:www-data /var/www

Thats all! Use this, at your own risk.

=======================

Solution

=======================

Right click of powersell and Run as Administrator

At command prompt execute the following:

Set-ExecutionPolicy Unrestricted -Force

Verification of replica failed. The forest functional level is Windows 2000.

Symptom – The client was unable to promote the Windows 2012 server named “pta_t30” as an additional domain controller in their windows 2003 domain t6.local.

Cause – We were getting the error: Verification of replica failed. The forest functional level is Windows 2000. To install a Windows Server 2012 domain or domain controller, the forest functional level must be Windows Server 2003 or higher.

Resolution – We performed the following steps so as to get the issue resolved:

– Ensured that the health of the Domain is good.

– Corrected the Time settings in the registry on secondary domain controller.

– The windows 2012 server named “pta_t30” was getting the IP address from DHCP so we assigned the Static IP address.

– Corrected the NIC binding and the provided order on “pta_t30”.

– Ensured that we are able to ping the domain and DC’s from 2012 server named “pta_t30”

– Raised the forest functional level to Windows 2003 and forced Active Directory replication.

– Ensured that we are able to promote the 2012 server as a Domain controller.
