  • Tips for doing SharePoint demos on virtual machines

    Tags: SharePoint, Windows 7, SharePoint 2010, Windows Server 2008, VMWare, Windows Server 2008 R2

    It's Friday and thought that I should share some small tips on how to make your SharePoint demonstration experience better. I assume that you have a quite powerful laptop with virtual machines running SharePoint.

    I used to do my demos directly in the virtual machine, in full screen mode. This requires that I have all the necessary client components installed such as Office, SharePoint Designer, the Windows Server Desktop Experience feature enabled etc. All this of course take resources such as memory and CPU from the virtual machine. Also Internet Explorer consumes CPU cycles and if you're using Firefox in the demo you get another memory hog in your virtual machine.

    A better approach is to use you local workstation as the client, In my case I have Windows 7 and VMWare running (yea, I like to promote them...) the virtual machines. This allows me to show a more realistic case when doing demos.

    The Network

    Networks The first tip here is how to configure the network for the virtual machines. I normally have one AD server and one SharePoint server which are connected using a separate network, so that I can use static IP addresses. Then I have a secondary network on the SharePoint VM which is host-only with known IPs, that is I can access the VM from the client using a browser or an Office application. I also have a third network on the VM which is connected to the Internet. I only enable this third NIC if I need to access web services and such from my VM.

    Then I add entries to the hosts (...\system32\drivers\etc\hosts) file with the IP numbers from the host-guest network so that I can use domain names instead of IP-numbers.

    Authentication

    I never have the host and clients on the same domain. My laptop is connected to my company's domain and the VMs all use their own directories. To get rid of annoying authentication prompts I use the Windows Vista/Windows 7 feature to store credentials - the Credential Manager.

    Credential Manager

    The Credential Manager allows you to save Windows credentials for a specific Internet or network address. Just add the name of the server, which you added to the hosts file, and then your default user username and password. Voila! You can now directly from your client/host browse to your virtual server using a good looking URL and without any authentication prompts.

    Firefox, Safari and other obscure browser does not use this credential manager and I use them to log in as other users.

    If you don't do this and log on to your server from the web browser you will be asked for the credentials every time you open an Office document from the server or when you open the site using SharePoint Designer.

    If you use these small tips you will have a much better experience when doing demos, developing or configuring your SharePoint virtual machines.

    Have a nice weekend!

  • Fix the SharePoint DCOM 10016 error on Windows Server 2008 R2

    Tags: SharePoint, Security, Windows Server 2003, Windows Server 2008, Windows Server 2008 R2

    If you have been installing SharePoint you have probably also seen and fixed the DCOM 10016 error. This error occurs in the event log when the SharePoint service accounts doesn't have the necessary permissions (Local Activation to the IIS WAMREG admin service). Your farm will still function, but your event log will be cluttered.

    On a Windows Server 2003 or Windows Server 2008 machine you would just fire up the dcomcnfg utility (with elevated privileges) and enable Local Activation for your domain account.

    But for Windows Server 2008 R2 (and Windows 7, since they share the same core) you cannot do this, the property dialog is all disabled due to permission restrictions. It doesn't matter if you are logged in as an administrator or using elevated privileges. The change is probably due to some new security improvements.

    DCOMCNG - all disabled

    The reason for it being disabled is that this dialog is mapped to a key in the registry which the Trusted Installer is owner of and everyone else only has read permissions. The key used by the IIS WAMREG admin is:

    HKEY_CLASSES_ROOT\AppID\{61738644-F196-11D0-9953-00C04FD919C1}

    Registry permissions on R2 Registry permissions on R1

    Image on the left shows the default permissions for Windows Server 2008 R2 and on the right the default settings for Windows Server 2008.

    To be able to change the Launch and Activation Permissions with dcomcnfg you have to change the ownership if this key. Start the registry editor (regedit), find the key, click Advanced in the Permissions dialog of this key and select the Owner tab. Now change the owner of the key to the administrators group for example, then set full control to the administrators group. Make sure not to change the permissions for the TrustedInstaller.

    Now you have to restart the dcomcnfg application and once find the IIS WAMREG application and then set the Launch and Activation settings that you need to get rid of the DCOM 10016 error.

    Unlocked!

    Good luck!

    WARNING: Changing the registry may seriously damage your server. All is on your own risk!

  • Developers, prepare for the 64-bit revolution

    Tags: SharePoint, SQL Server, Virtual Server, Hardware, Windows 7, SharePoint 2010, Windows Server 2008, VMWare, Virtual PC

    The day has come when Microsoft officially started to talk about the next version of Office 2010 clients and SharePoint Server 2010 (no longer Office SharePoint Server). We have since some time known that SharePoint 2010 will be supported only on a 64-bit platform, just as Exchange 2007.

    The new stuff revealed yesterday (as preliminary) are that not only is 64-bit required, it will only be supported on the Windows Server 2008 64-bit platform (including R2) and it will require that you have SQL Server 2008 on a 64-bit platform. There are some other interesting facts that you should check out also in the post (and on about 1.000 other blog posts), but this post is not just about these news.

    The interesting parts of this announcement is that now is the time to learn the 64-bit platform for real and especially Windows Server 2008 R2 and SQL Server 2008, not everything is the same; registry hives, file system, settings, know when to use int (Int32) or Int64 etc etc. You can start now, it's no time to wait! Make a decision to only install your new SharePoint installations on the required SharePoint 2010 hardware, make sure that you have that in your development environments and on your virtual machines. Yes, it will in many cases cost you a bit in new hardware.

    I think that this is the time when 64-bit really will kill the 32-bit era.

    As a bonus I can tell you one thing that I didn't know was achievable. My main laptop runs 32-bit Windows 7 and not 64-bit due to that it does not have the 64-bit driver support for the peripherals and I usually use(d) Virtual PC to virtualize my development servers. Downside with Virtual PC is that you guest machines can only be 32-bit and I don't want to have a Hyper-V laptop in 64-bit mode so I thought that I had to get me a new laptop (which is due for later). I was preparing for the worst of having a dual boot. Fortunately I did a test using VMWare Workstation today and found out that as long as you have a 64-bit capable hardware (which I have) you can host 64-bit guests on a 32-bit host OS. Did you know that, I did not! So I will spend this evening preparing my new development VM's. If you are in the same situation as me, stuck with a 32-bit OS for some time, head on over to VMWare and run the 64-bit compatibility checker and then dump Virtual PC and get VMWare Workstation.

    Welcome to the 64-bit world!
