Windows Keychain?


I had no idea that windows itself can save passwords, similar to OS keychain. Unfortunately this can be a security issue since your credentials are saved on a machine. It can also cause some network resources to stop connecting if your computer continues to use credentials that are no longer valid. We got an error in the windows logs with something like this:

"Group Policy object did not apply because it failed with error code '0x80070005 Access is denied.' This error was suppressed."


The way we fixed it was to remove the saved credentials. You can manage this by running the following in a run window:

rundll32.exe keymgr.dll, KRShowKeyMgr

You can also get to it this way in Windows 7 Pro. It's called the Credential Manager or Vault.

Windows 7 Credential Manager

1. Click Start, then Control Panel
2. Click User Accounts and Family Safety
3. Click on Credential Manager

In Windows 7 there is a slightly different interface than opening the key manager from the run menu, but it manages the same list.

Of course there are a lot of websites with these details, and windows will even show you how to use it if you search for the right key words in help. I just wanted to shine a little more light on the subject because who knew that windows has a key manager?

Remote Desktop to Windows 7 from XP

By default you cannot remote desktop (mstsc) into a machine running Windows 7. This is a pretty easy fix, but I had to search a little bit for the solution.

First of all, you will want to be in the same workgroup or domain. If you are not, then you may need to fully qualify the name of the machine when remoting into it. (ie machine.domain.network or something)

Enable Remote Desktop on Windows 7


1. Right Click on My Computer
2. Click Properties
3. Click on Remote Settings in the menu on the left
4. Change the radio button from "Don't allow connections to this computer" to "Allow connections from computers running any version of Remote Desktop" (if you select the bottom one then you will not be able to remote from XP)
5. If there are any users that are not administrators of the computer, you can add them by clicking "Select Users" and adding their account. Otherwise they will get an error about terminal services when they try to use Remote Desktop.
5. Click OK




This is the same place where you can change the workgroup or add the computer to a domain.
The process is very similar on Windows XP if you want to go the other direction. Remote Desktop can be accessed through the start menu in accessories, but I prefer just running mstsc in the run window.

Windows 7 Drivers for ASRock 939dual-SATA2


I recently installed Windows 7 Pro x64 on my desktop and almost all of the drivers were automatically installed. Two important ones were not: Onboard LAN and my SB Audigy 2 card.










The ASRock website (http://www.asrock.com/mb/download.asp?Model=939Dual-SATA2&s=939) only has XP drivers, which won't work unless you run it in compatibility mode. This is pretty simple:

Windows 7 Compatability Mode:

1. Right click on executable
2. Select properties
3. Click on the Compatability tab
4. Check "Run this program in compatibility mode for:"
5. Select Windows XP (Service Pack 3)
6. Click OK and run the program

As for the audio, since I don't use the onboard audio I haven't checked to see if it works although I have read about other people having issues. Even though this board has 7.1 channel sound I don't recommend using it because there was a lot of static noise. At least for me.

Why Blog?


It seems that very few will be interested in this blog because most people will have a technical skill much higher or lower than me, making it boring to the vast majority. Yet, if nobody reads, I can still say that I have learned, and that might help me sometime when it counts.

On the other hand, if it does become quite popular I will make a lot of money through AdSense.

Windows 7 Installation

Like many university students I am able to participate in the MSDNAA. Therefore I was compelled to postpone my studies and install Windows 7 on my desktop at home. I started out fairly confident as I had already installed the Beta, RC, and enterprise release on several computers at work including a VM, and I'm pretty good at this type of thing by now. However this one almost defeated me.

I can usually handle one or two things going wrong, but it seems that everything went wrong this time.

One, the download from MSDNAA was corrupted twice for me, so I had to get an ISO from an alternative source.

On top of that, Roxio was not able to correctly burn to DVD as I had suspected from searching forums. I had to download IMGBurn which works great. One of these problems was giving me an error about "CD/DVD driver missing".

Third, my system has three different types of RAM, one of the types being a pair. The system will get memory errors unless the sticks of memory are placed in just the right order. (That is a post for another day)

After a week of asking people for ISOs and burning a half-dozen bad DVDs I finally have Windows 7 installed. I can say that it was worth it, but it would be nice if the MSDNAA website had an MD5 sum on it.
