Fakeraid with XenServer

June 17th, 2009 No comments

Do you also have “fakeraid”, and want to use it with XenServer?
Well, you might be in luck, or maybe not :)

If you use RAID0, RAID1 or RAID10 you are lucky.
However, if you use RAID5 like me, you have a problem.

Attaching disk to XenServer Guest

June 17th, 2009 3 comments

It is possible to attach a hard disk directly to a XenServer guest.
I use this so I can always read these disks with another Windows Server, whenever the XenServer host would fail completely.

Installing SBS 2008 on XenServer

June 17th, 2009 2 comments

Hi,

When trying to install Windows Small Business Server 2008 on a XenServer System, i encountered several errors.

The first ones I don’t really remember, but they where fixed by installing the XS-Tools before starting the SBS configuration wizard.

  • Install SBS 2008
  • On first boot (when the Configuration Wizard shows up), press Ctrl+Shift+Esc
  • Choose xs-tools.iso in the DVD Drive dropdown list
  • Go back to the Task Manager, click on “File”, “New Task”.
  • Browse to the cd and run the setup.
  • After this reboot the server (once or twice).
  • Continue with normal installation

Then there was another problem when trying to install on XenServer 5.5. At some point in the installation the server rebooted and then stated that you should retry the setup.
The only fix for this problem that I found was to choose  ”Other install media” as the Template, and not “Windows Server 2008 x64″

How to add an Edge Subscription

June 17th, 2009 No comments

Here are the steps you need to take, and some things to keep in mind

  • Open Exchange Management Shell (as Administrator)
  • New-EdgeSubscription -file C:\EdgeSubscription.xml
  • Answer “Y”
  • Transfer EdgeSubscription.xml to the Exchange Server
  • Open Exchange Management Console
  • In the left tree choose “Organization Configuration” and then “Hub Transport”
  • In the Actions pane click “New Edge Subscription”

Check if everything is working:

  • In the Exchange Management Console, Organization Configuration, Hub Transport, Edge Subscriptions.
    Your Edge Server should be listed
  • Open Exchange Management Shell and run Start-EdgeSynchronization

Problems:

  • “New-EdgeSubscription : The task couldn’t add the certificate to the ADAM directory service store. Error: access is denied.”
    Open Exchange Management Console as Administrator
  • “Start-EdgeSynchronization : unable to contact EdgeSync service”
    Go to Services, search for “Microsoft Exchange EdgeSync”, and click Properties
    Change Startup type to Automatic and Start the service.
  • Firewall Issues:
    I’ve installed EdgeServer together with Forefront TMG. You have to allow port 50636 from Exchange to EdgeServer
  • Also bare in mind that the EdgeSubscription.xml file is only valid for 24 hours or so

File Server publishing through OWA

March 27th, 2009 No comments

Hi,

I’m here with a new problem that I solved a while ago, but I do think lots of people will benefit from this.
Outlook Web Access 2007 has a new feature “Documents”. It can be used to access your documents through owa from anywhere.

The problem is, that even when you configure everything, it still doesn’t work. You can only access the local exchange server, but no other computer or server. Because you always get the following error:

authentication-failure

Authentication Failure:
Outlook Web Access was unable to retrieve the requested SharePoint document or folder. This may have occured because of the way your Microsoft Exchange and Microsoft SharePoint servers are configured. You can try going directly to the resource by copying the link you typed and pasting it into Internet Explorer. For more information, contact technical support for your organization.

The error states an error with a SharePoint document, but we do want to access a File Share.

My Windows Live Messenger layout proposal

March 20th, 2009 No comments

Hi,

I’ve been using the new Windows Live Messenger 2009 since it was available as a beta.
In this version there is a bug with the display pictures. It doesn’t remember the size you selected.
It is a known bug, but still, in the final release, it’s still there !

For now, I just hide the display pictures, as they take too much space in the “medium” setting (How big would “Large” be?).
But even with small display pictures, there is a lot of wasted space.

The reason for this post is that I made a simple redesign of the layout, using the small display pictures.

So, what do you think? Should the Messenger developer team change their layout?

edit: Due to request I’ve added a possible screen when used with a webcam.
edit2: I also added the original layout.

Do you like my proposal layout?
