When queried for an existing A or AAAA record serving as glue (an address record at or below NS records at a delegation point), the authoritative name servers for .com and .net respond with the glue record in the answer section. However, the answer is not marked authoritative, i.e., the AA bit is not set. While this behavior conforms to the DNS standards, recent authoritative servers do not respond this way. Instead, when queried for a name at or below a delegation point, recent authoritative servers respond with a referral to the delegated zone. This behavior is also supported by the DNS standards. More info

My take on this:
This will effect people who fail to properly create a glue record with the registry. I have seen people setup A records to point to company X nameservers ips. Well this is not going to fly anymore, you will need to properly setup the nameservers with the registry.

DNS Cycle:
A users request a domain name > This request goes to the root servers first> the root server will now only return the NS record without the A record > **Referral to the actual nameservers for the domain ** > The actual nameserver will return the A record for the domain > the user is then directed to the hosting server.

Current cycles :

The root nameserver were returning the A record for the nameserver. So it was actually doing query on the assigned nameservers for the requested domain. This added a few miliseconds to the users request for the web content. By eliminating this cycle should increase the response time.

I used yahoo.com as an example of what a domain request looks like
*** this is returns the nameservers from the root server *****

*the nameservers are then queried for the A record for yahoo.com. as you can see they have their servers load balanced for failover. *Multiple ips were returned for their A records *

Fast DNS response within 1ms , good job yahoo

Possible solution Solution : find the class.IXR.php file (under wp-includes), edit the file, and look for function output($xml) FInd the line that calculates the length $length = strlen($xml); and replace it by $length = strlen($xml)+3;

or if modsecurity is enabled set the following in an .htaccess file <files xmlrpc.php>SecFilterInheritance Off </files>

This occurred when using a live cd in a virtual player under bridge mode. The app loads after a virtual player reboot, but restarting the service within ssh returned the error. So I did a hard reboot on the host machine which resolve the issue.

You will also need to make sure the host name is correct in the ejabberd cfg file.

Bug in : TurnkeyLinux Ejabberd version: 2009.10

issue: When using the interface in internet explorer. The P key bring up the help menu option and should not. There have been talks about this happening with Safari and Opera.

Speeqe released an update on 1/18/2010. As of today Turnkey has not updated their source so a manually fix is needed if your using turnley version.

The uppdated files can be downloaded from Speeqe. Thanks to Nathan Zorn for providing this fix.

We are in the process of touching base with Turnkey to see if they are aware.

You can attach a database without the logfile by attaching, then clicking the logfile location, and click the remove button. After you click OK a new logfile will be created for your database

Server object error ‘ASP 0177 : 800401f3′

Server.CreateObject Failed 800401f3

Solution
the ASPMail component is NOT supported on Windows 2008 You will need to use the System.Net.Mail Component for .net. I pasted some sample code to get you started below. Please be advised that this sample will need to be modified some.

<%@ Import Namespace="System.Net.Mail"%>
<script language="VBScript" Debug="true" runat="server">
sub Page_Load()
Dim oMsg As New MailMessage()
oMsg.From = New MailAddress("mailbox@yourdomain.com")
oMsg.To.Add("recipient@theirdomain.com")
oMsg.Subject = "This is an email"
oMsg.Body = "<HTML><BODY>Hello World!</BODY></HTML>"
Dim smtp As New SmtpClient("scriptmail.yourdomain.com")
smtp.Send(oMsg)
oMsg = Nothing
end sub
</script>
More information on this component can be found at http://www.systemnetmail.com/

You do not have permission to view this directory or page using the credentials that you supplied because your Web browser is sending a WWW-Authenticate header field that the Web server is not configured to accept.

HTTP Error 401.2 – Unauthorized: Access is denied due to server configuration. Internet Information Services (IIS)

Technical Information (for support personnel)
Go to Microsoft Product Support Services and perform a title search for the words HTTP and 401.
Open IIS Help, which is accessible in IIS Manager (inetmgr), and search for topics titled About Security, Authentication, and About Custom Error Messages.

————-

Fix :

you will need to change the authenication method to basic instead of Integrated authentication. This mostly effects older browsers.

There is a slight draw back to this .With basic , the login details will be sent in plan text..

Common reasons
No authentication protocol (including anonymous) is selected in IIS. At least one authentication type must be selected. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
253667 Error message: HTTP 401.2 – Unauthorized: Logon failed due to server configuration with no authentication
Only Integrated authentication is enabled, and an older, non-Internet Explorer client browser tries to access the site. This happens because the client browser cannot perform Integrated authentication. To resolve this problem, use one of the following methods:
Configure IIS to accept Basic authentication. This should only occur over SSL for security purposes.
Use a client browser that can perform Integrated authentication. Internet Explorer and new versions of Netscape Navigator and Mozilla Firefox can perform Integrated authentication.
Integrated authentication is through a proxy. This happens because the proxy doesn’t maintain the NTLM-authenticated connection and thus sends an anonymous request from the client to the server. Options to resolve this problem are as follows:
Configure IIS to accept Basic authentication. This should only occur over SSL for security purposes.
Don’t use a proxy.

Ok that was out of the way. performing a Drupal install for the first time using IIS version 7 and windows 2k8 server. After entering the database information I was faced with a 500 error message that gave me a lot of information. SIKE

The 500 error gave me nothing at all, did not tell me where the error was or which file caused the error. By default IIS7 will suppress the PHP errors and will not show them in the browser. This is the case even if Display_errors is turned on in the php.ini file.  I had to enable the directive to save the error to a flat file error_log= /path

some techs have enabled enabled IIS7 errors server wide using
%windir%\system32\inetsrv\appcmd.exe set config -Section:system.webServer/httpErrors -errorMode:Detailed

Issue 1
If you have tried installing Drupal on Windows Vista or Server 2008 recently with PHP configured to use Microsoft’s FastCGI handler, then you will have no doubt encountered a problem where you are unable to make any updates to your site configuration. This is because the REQUEST_URI variable when using Microsoft’s FastCGI handler on IIS 7 does not include the query string as it does with other Web servers such as Apache. Until the IIS team release a fix for this you’ll need to use a work around to rectify the issue.

The easiest way to rectify the issue at the moment is to modify the request_uri() function in Drupal. To do this simply open the Drupal bootstrap file in “includes/bootstrap.php” find the appropriate section of code and modify as follows;

function request_uri() {

return $uri;
}

Then I found i was receiving the error
