How to fix "An authentication error has occured (Code: 0x8009030e) " error when trying to connect to a Hyper-V guest on Windows 2008 using the Hyper-V Manager

Leave a reply

I was trying to open up a guest in the Hyper-V Manager console and I got the following error:
“An authentication error has occured (Code: 0x8009030e) ”
I then tried to open a few other guests and got the same error. I restarted the Hyper-V Manager, but had the same problem.
The simple fix is to log out of the server, then log back in and you will be able to open the guests again.
This happens if you are usually disconnecting from the host, rather than logging in and out each time as the credentials become stale.

How to fix "HTTP Error 403.14 – Forbidden The Web server is configured to not list the contents of this directory"

We had a fresh install of Windows 2008 and Visual Studio 2010 on a developers machine that was getting this error when trying to access a MVC 2.0 .Net 4.0 website hosted locally on IIS7. Various fixes talk about making sure there is a default document, and also about turning on directory browsing, but neither of those work. (MVC 2.0 does not need a default document specified).

The issue was that .Net framework 4.0 had not installed correctly, so here is what you need to do to fix it.

1.) Run a command prompt as Administrator.

2.) Copy and paste the following text “C:WindowsMicrosoft.NETFramework64v4.0.30319aspnet_regiis.exe -i”

This is assuming that you have already installed MVC 2.0 And .Net Framework 4.0 , but not in the correct order.

How to fix the Event ID 521 "Volume Shadow copy operation failed for backup volumes with following error code '2155348129' " error when you try to backup a Windows 2008 server with Windows Backup

5 Replies

I was trying to do a single backup of Windows 2008 server using the built in Windows Backup program, but no matter what settings I chose, or where I backed it up to, it would always fail with the following error in the event log - Event ID 521 ” Volume Shadow copy operation failed for backup volumes with following error code ’2155348129′ ”

I decided to check the disk and found that there was an OEM partition installed and that it was set to active. I then right clicked on the C: drive partition and set that to active.

To do this, go to Control Panel , then Administrative Tools, then into Computer Management. In Computer management, go to Storage, then click on disk management to display your list of hard disks. You can then set your C: drive to be active by right clicking on it and sellecting Mark Partition as active.

 

After this the backup worked fine. The problem with it is that in order for Volume Shadow copy to work, the partition with the operating system  has to be set as active.

How to add the Bluetooth stack to Windows 2008

Leave a reply

I bought a cheap Bluetooth dongle the other day for my desktop PC so that I could talk to my Nokia phone and also to my Lego Mindstorms controller. After plugging in the dongle, it could not detect a driver which I thought may have been an issue, but seeing as it said it worked with Windows Vista, I thought it just  may have worked.

I did some research and found this website that had information and a Bluetooth stack available. I have a copy of this file that you can download from the link below.

Here are the steps to install the Bluetooth stack.

1. Download the modified Microsoft Bluetooth Stack x64 Drivers and unzip it to your local hard drive.

2. Go into device manager , right click on the “Unknown Device“  and choose “Update Driver Software”

3. On the “How do you want to search for driver software” dialog, select “Browse my computer for driver software”

4. On the “Browse for driver software on your computer” dialog, click the “Browse” button and browse to the folder which contains the unzipped copy of the Microsoft  Bluetooth Stack drivers you downloaded previously.

5. Click “Next”, and follow the instructions to complete the driver update and repeat for any other Unknown Devices.

How to enable virtualization on a Dell Optiplex 755 to run Hyper-V

34 Replies

I have been building some test Windows 2008 Hyper-V server’s on Dell Optiplex 755 workstations with 8GB of RAM recently, and I thought I would let you know what settings to change in the BIOS to make this work.

At first I was getting some errors like these below:

  • Hyper-V launch failed; Either VMX not present or not enabled in BIOS.
  • Hyper-V launch failed; at least one of the processors in the system does not appear to provide a virtualization platform supported by Hyper-V.

This was happening because I had missed the Execute disable setting in the BIOS. To fix this, boot the computer and press F2 to enter the BIOS.

In the BIOS you need to change the following settings

  • Security > Execute Disable (set to On)
  • Performance > Virtualization (set to On)
  • Performance > VT for Direct I/O Access (set to On)
  • Performance > Trusted Execution (set to Off)

Save and exit the BIOS, then power the computer down. You must power it down for the settings to take affect.

You will now being able to run Hyper-V on your Dell workstation!

How to extend the evaluation period in Windows 2008

Leave a reply

I run Windows 2008 as a desktop OS as it is very stable and offers great features. Should you wish to trial it for longer than 60 days, you can do so by re-arming the evaluation period to give you a total trial of 240 days.

To do this go to Start then Run and type slmgr.vbs -dli and hit enter to see how long you have left.

To then rearm your evaluation period go to Start then Run and type slmgr.vbs -rearm  and hit enter. After a few seconds you will get a message that asks you to reboot to complete the action.

When you reboot you will have extended the evaluation period.

How to Enable Virtualization Technology on a Dell 2950 to use Hyper-V in 64bit Windows 2008

Leave a reply

Your processor must support VT and also have it enabled for you to be able to use Hyper-V in Windows 2008 server 64bit.

To do this on a Dell 2950, follow the steps below.

Go into the BIOS by pressing F2 as the server is booting.

Use the down arrow key to go down to CPU Information and press enter.

Use the down arrows to go down to Virtualization Technology and press the space bar to enable it.

Press Escape twice , then choose Save changes and Exit.

The server will do a hard power down by itself, then reboot.

Once Windows has booted, you can then check to make sure that Hyper-V is running and has no errors in the event log for it.

How to fix OAB not updating in Exchange 2007

2 Replies

We had a problem where any new user mailboxes that  were added to the Exchange server were not appearing in the address books of Outlook 2007 clients running in cached mode.The address book was up to date in OWA, but our cached Outlook clients wouldn’t update even after forcing a download of the OAB. If I took the Outlook 2007 client out of cached mode, they would see the latest address book.

The way we fixed this was by going into Exchange Management Console (EMC) , Organization Configuration , Mailboxand then clicking on the Offline Address Book tab. Double click on the Default Offline Address Book then click on the Distribution tab and untick “enable web based distribution” .OK out of this menu, then go back in and retick the “enable web based distribution” , add the servers that you want to use for web distirbution and OK back out again.

You should now have an updated OAB when you download it again.

Another point to note is that if you have multiple Exchange servers is that you should have all of the servers are added in for “web based distribution”

How to disable UAC in Windows Vista and Windows 2008 Server

Leave a reply

I use Windows 2008 as a workstation for it’s stability, features and higher memory limit. The one annoying thing that I found as a user is User Access Control (UAC) which prompts you any time a change is required such as the running of a new program. While I think the feature is great for a new computer user who could be duped into installing some malicious software, it is super annoying for me.

The easiest way to disable this feature is by using a built in program called “MSconfig” .

Go to Start – then Run and type “msconfig” and the program will load.

Click on “tools” along the top menu and then scroll down to “Disable UAC” and click on it so it is highlighted, then click on the “Launch” button in the bottom right hand corner.

This will launch a command prompt which should say that “The operation completed successfully.”

You can then close this command prompt and then click OK back in the MSconfig program window to close the program.

Restart your computer and UAC will be disabled.
