RDP and certificate

If you have configured RDP on Windows 2008, 7 to use an internal certificate for computer authentication, CRL will only work if the only published location is an HTTP endpoint.  If you have multiple end point, the CRL checking will not work.

Alternative is force RDO to use legacy encryption by creating a RDP file with

authentication level:i:0

Note to self, Outlook doesn’t have intellisens

Crazy past couple of weeks, been rushing like mad and very much sleep deprived all for work.  So this afternoon while I was replying to an email, I keep hitting Ctrl-Space waiting for intellisense to show up while I was in Outlook.  I went crazy thinking why is my intellisense broken, only realising I’m actually in outlook.  That’s just telling me its time to get some rest.

PDC 2008

I've thoroughly enjoyed my time at the PDC this year, the biggest announcement was obviously the cloud services with the Windows Azure platform.  But the greatest thing is the chance to network with other developers and Microsoft product team members.

This was my first PDC experience and I had high expectations, I think the conference overall was organised pretty well. But I have to say was disappointed that we don't get a nice show bag, was expecting some kind of nice backpack or laptop bag given the price of the conference ticket, but instead only got a plastic show bag

It would also be nice if the "Ask the experts" session was slightly better organised.

WCF WSDL and ASMX SOAP Extensions

Interesting observation today, if you have an invalid ASMX soap extension registered in your web.config file.  WCF will not render wsdl from its metadata endpoint.  I didn't think the two was related, but there must be some connections between them.

MOSS and antivirus scanning exclusion

If you're running an OS level antivirus scan on your MOSS production servers, you might run into decreased performance and random lock ups.  Check out and add in the necessary exclusions to your virus scan to stop your scanner from competing with Sharepoint.

Office 2007 on Vista authentication prompts with Sharepoint docments

Under Windows Vista, sometimes when you open an Office document stored on a WSS or MOSS site, Vista keeps prompting you for user credentials and integrated security just doesn't seems to work.  This can be caused by a number of different configuration issues in your environment and sometimes you need to have all the stars aligned for it to work.

  • First thing to check is make sure your Sharepoint site is working with integrated security to start with, that is you have configured either NTLM or Kerberos correctly.  So when you navigate to your Sharepoint site in Internet Explorer with your desired url, it should not prompt you for username or password.

    If you are having trouble here, check these items.
    • Make sure the url you're using is in the Intranet zone and not the Internet zone.  By default on Vista, only Intranet zone does integrated security.
    • Check that you are using NTLM on your WFE server.
    • If you are using Kerberos, make sure SPN are configured correctly.  Check out this post from Martin Kearn on kerberos and Sharepoint.
  • Now make sure Vista is running SP1, if not, install the hotfix on your clients.
  • Add AuthForwardServerList to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters in the registry.  The value in this key should be the URLs of your sharepoint stie.  Restart the WebClient or for the changes to take effect.  I've used the new group policy preference to deploy this key.

With everything configured correctly, there shouldn't be any more annoying authentication prompts from Vista when you open an Office 2007 document.

Why are data charges so high?

I think it is crazy that you could be charged $1 per MB of data over wireless.  In Australia, if you're not careful in choosing your provider, you could be in for a very nasty surprise.  I feel sorry for SMB owners who are not that technical and sign up for these outrageous prices.
