Resolved a "STOP 0xC000021A" error on the Windows XP machine

windowsXP The machine of my friend’s all of sudden started to hung up before the Windows logon screen. Later it went into a loop of continuously rebooting. I came in with safe mode and disable the auto reboot upon error feature, then I saw the famous death blue screen with the following error message every time:

Stop: c000021a [Fatal System Error]
The Windows subsystem system process terminated unexpectedly with a status of 0xC0000006 (0x77f632fc 0x004ff228) The system has been shut down.

According to Microsoft knowledge base article, "The STOP 0xC000021A error occurs when either Winlogon.exe or Csrss.exe fails." But the root cause of that varies, so it is very hard to pin point the problem and fix it easily.

Unsuccessful methods I tried:

How to trouble shoot SharePoint with “critical error”

MOSS 2007These days the MOSS site went down a couple time, every time there was the following error messages:

page has encountered a critical error. Contact your system administrator if this problem persists.

At first, we could reboot the database and application servers to let the problem go away. But rebooting is not the good choice. Finally I figured out it was not about the database.

Here is what I did to find the real issue behind the generic error message above.

Resolve Access Denied Error while creating new article page in SharePoint MOSS 2007

MOSS2007[1]A user with Full Control permission on the top site could not create an article page. The error message was Access Denied.  I tried different ways to resolve this issue, include put her Full Control permission directly on the top site and Page library, but still had the same issue. Then I assign Full Control, Approve and Contribute and all permission levels to her, I got the following error:

List does not exist

The page you selected contains a list that does not exist.
It may have been deleted by another user.

But this user can do everything else except the Create Page from the Site Action drop down. From the URL, you can see the Create Page is using /_layouts/CreatePage.aspx file which I believe is using publishing template

How to change the Domain name URL for the SharePoint site

MOSS2007[1] We just launched a new Intranet web site powered by the SharePoint 2007 (MOSS 2007). Everything works fine except the URL. By default, the SharePoint services uses the computer name of the server. But we need a nice name like “http://intranet” as the new site name.

We created a new DNS record named “Intranet” and pointed it to the SharePoint server. But it only did the initial re-direction, and it came back to the default http://servername/Pages/default.aspx URL again.

How to correctly import no-English (UTF-8) characters from MySql4 into MySql 5.0 with mysqldump

I tried to upgrade my WordPress to 2.9.2 but I had to upgrade my database MySql first since WordPress 2.9.2 requires higher MySQL version. Just like I usually did with the database backup routine, I used “mysqldump” command to export data from MySQL 4.0 and then used “mysql” to import data into MySql 5.0. Everything seemed OK at the first, but I later on found out all my Chinese characters turned into non-readable mess characters.

The problem was my host provider, 1 and 1 located in Europe, uses “latin1-german1_ci” as default database collation. And the dumped SQL script from the MySql 4.0 does not have the database collation information even it is in UTF-8, so all new tables created in the new MySql 5.0 have the latin1_german1_ci as the default collation and latin as the default character set.

How to add weather and traffic information to SharePoint page

Recently I added some weather and traffic information to one of our SharePoint page, and would like to share the process here. Of course, you will have to select the right web service based on your location. I use Georgia state here as the example.

Normally to add external information to the SharePoint page, you can use RSS feeds, or the Javascript code snippet provided by the external web site.

Weather:

I selected accuweather.com not weather.com since weather.com has domain name restriction.

Here is simple steps to add weather on the SharePoint page.

How to open SharePoint link list item in a new window

In SharePoint 2007 (WSS 3.0), you can put any URLs in the Links List. But when you click any of these links, they will be opened in the same browser window instead of in a new window.

I checked the Internet, and found a couple of ways to open the links list in a new window. The first one was the simplest one as I am concerned. I implemented and it worked for me.

Post emails onto SharePoint list

Challenge:

We are using a service called Roam Secure Alert Network to notify subscribers about any news needs immediate attentions. These alerts can be posted through Web, Email and SMS. And the subscriber can receive  alerts with emails, phone text messages.

Recently we need an internal SharePoint web page to be developed to show all these alert messages. Since the Roam Secure system is not part of our system, and did not provide any RSS feeds due to secure concerns. We could not set up any data connection to retrieve these message from their system.

The simple way is to use the Incoming email feature of SharePoint to post these messages in a new list.

Issues with creating Database Connections to Oracle in SharePoint Designer 2007 (Resolved)

Challenges:

I tried to connect to Oracle database in SharePoint (MOSS 2007). But got the following error when I tried to create a Database connections in Designer 2007.

1), Use custom connection string;
2), Select Microsoft .NET Framework Data Provider for Oracle as the Provider Name;
3) Post the below as the Connection String:

Password=<passwd>;User ID=<userID>; Data Source = <mydatasource>; Persist Security Info=True; Provider=OraOLEDB.Oracle;

4), It seemed the Oracle db can be connected, but could not find the root catalog since the "Initial Catalog=root;" was appended to the above connection string automatically.
5), and the error message is:

Server Error: An error occurred while retrieving the list of Tables from the root Database: The query you are trying to execute contains syntax errors.

I searched on the Internet, and was told there is a way to use BDC(Business Data Catalog). But I just need a simple way to show Oracle data on a SharePoint page. BDC connection is too much for me at this point.

How to pass InfoPath form fields to SharePoint workflow but hide from Document Library item properties

Challenge:

Create a form in InfoPath 2007 and implement a SharePoint Workflow to it for approval processes. In each step, a Status field in the InfoPat form should be updated automatically according to the change of workflow task status. So a different view in the InfoPath can be opened based on the Status field in the form.

But after the InfoPath was published to the SharePoint (MOSS 2007 with InfoPath Form Services turned on) as Document Library and Content type, the Status field could not be displayed when “Set Field value in Current item” action was selected in the workflow design. Even it was promoted to be available in the SharePoint document library.

How to fix non working “Edit this task” button of SharePoint workflow notice in Outlook and InfoPath 2007

Challenge:

Set up a workflow for the InfoPath form in the MOSS 2007 and the workflow worked fine. The approval notice had been sent to the next person’s mailbox, but the Edit this task button on the toolbar of Outlook 2007 did not work. When you click it, nothing happened. You can click the infopath xml link in the message body and the infoPath form was opened. And the Edit this task button in the InfoPath 2007 message bar did not work either.

According to Kerry’s MOSS blog:

This is apparently related to Outlook 2007 using InfoPath to display the approve/reject form. This form contains a CLSID of {00000000-0000-0000-0000-000000000000}. This CLSID is apparently “kill bitted” on some systems and is prevented from being displayed.
