Today I received the following error while getting ready to do some new development for my URL Rewriter.

TF53002: Unable to obtain registration data for application VersionControl.
TF30040: The database is not correctly configured. Contact your Team Foundation Server administrator.
TF30059: Fatal error while initializing web service
TF30063: You are not authorized to access myserver.443. (type TeamFoundationServerUnauthorizedException)

This is very weird because I was just working on it earlier this week, without any issues.  So I go in to check the recent update history of Windows Update and to my surprise I see 13 new updates, mostly security related.  And since TF30063 is a security related exception, I think I found the culprit.  Here are the KB articles of the updates that were done for reference:

1. KB956744
2. KB973540
3. KB947319
4. KB971032
5. KB960859
6. KB971557
7. KB973869
8. KB973507
9. KB973354
10. KB961371
11. KB971657
12. KB890830
13. KB973815

So I started searching the web for each of those error messages, and I found a ton of old articles related to the SP1 release of Team Foundation Server.  However I upgraded about a year ago to SP1 so I doubt that is the issue.  But during my searching I found an obscure article referencing KB926642, which on first pass I just brushed off as not being the issue.  But as I started reading it I remembered that I do access my server through a CNAME address, and one of these security updates might have disabled Windows Authentication through CNAME’s.  So I tried as the article suggested.

\\myserver\c$ — works
\\myserver-cname\c$ — tells me I am not authorized

So I followed Method 1 in KB926642:

Method 1 (recommended): Create the Local Security Authority host names that can be referenced in an NTLM authentication request

To do this, follow these steps for all the nodes on the client computer:

1. Click Start, click Run, type regedit, and then click OK.
2. Locate and then click the following registry subkey:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0
3. Right-click MSV1_0, point to New, and then click Multi-String Value.
4. In the Name column, type BackConnectionHostNames, and then press ENTER.
5. Right-click BackConnectionHostNames, and then click Modify.
6. In the Value data box, type the CNAME or the DNS alias, that is used for the local shares on the computer, and then click OK.Note Type each host name on a separate line.

   Note If the BackConnectionHostNames registry entry exists as a REG_DWORD type, you have to delete the BackConnectionHostNames registry entry.

7. Exit Registry Editor, and then restart the computer.

And everything is working great now.  So if you are using a CNAME with your TF server, you may want to consider adding the CNAME in to the BackConnectionHostNames.  It will not only help your TF server, but all your other connections to this server that use Windows Authentication and the CNAME.  Hope this helps somebody else besides me.

Found this great new, well new to me, service on Amazon called Listmania. It allows you to bundle Amazon products in to a list for easy consumption. So the first list of Amazon items I thought of trying out as a Listmania list was a post a I did a while ago titled “Recession Proof Your Programming Skills”

In this economy you have to do everything to keep your skills fresh and current so that employers find you a desirable hire. I really though the tips provided in 8 Ways to Recession-Proof Your Programming Career where spot on when this article came out last year. And now that the TechRepublic has released 10 kills developers will need in the next 5 years. I have decided to give you some of my favorite Wrox books that align very well to this TechRepublic article.

The Economy may or may not seem so bleek anymore depending on who you talk to, but the message is still the same, keep your skills current and marketable. That is why I put together the list originally and it is still why I am porting it to Listmania.

Click here to check out my “Recession Proof Your programming Skills” Listmania list.

I will try to keep this up to date with new books I find useful and marketable in the way of programming skills, if you have any comments or suggestions for my list please feel free to leave them below.

I am not going to comment too much on Linus Torvald’s comments in this Linux Magazine article, because I feel they are very transparent and they mirror my own.

I’m a big believer in “technology over politics”. I don’t care who it comes from, as long as there are solid reasons for the code, and as long as we don’t have to worry about licensing etc issues.
I may make jokes about Microsoft at times, but at the same time, I think the Microsoft hatred is a disease. I believe in open development, and that very much involves not just making the source open, but also not shutting other people and companies out.

There are ‘extremists’ in the free software world, but that’s one major reason why I don’t call what I do ‘free software’ any more. I don’t want to be associated with the people for whom it’s about exclusion and hatred.”

He also went on to say, that people bashing Microsoft for submitting drivers, and congratulating the likes of IBM for doing the same are being hypocritical.

I agree that it’s driven by selfish reasons, but that’s how all open source code gets written! We all “scratch our own itches”. It’s why I started Linux, it’s why I started git, and it’s why I am still involved. It’s the reason for everybody to end up in open source, to some degree.
So complaining about the fact that Microsoft picked a selfish area to work on is just silly. Of course they picked an area that helps them. That’s the point of open source – the ability to make the code better for your particular needs, whoever the ‘your’ in question happens to be.

Does anybody complain when hardware companies write drivers for the hardware they produce? No. That would be crazy. Does anybody complain when IBM funds all the POWER development, and works on enterprise features because they sell into the enterprise? No. That would be insane.

So the people who complain about Microsoft writing drivers for their own virtualization model should take a long look in the mirror and ask themselves why they are being so hypocritical.

Two thumbs up Linus.

I will be speaking at the Philly.NET Code Camp 2009.1 tomorrow. So if you read this blog, come up to me and say hi. I don’t bite.

After my presentation tomorrow on “Gooey GUI… Programming in Visual Studio”, I will be posting my presentation and links for everybody that couldn’t attend or did attend and wants a quick reference.

See you tomorrow.
