Remote Desktop Connection Limit Exceeded

Maher Al-Jendasi — Mon, 12 Feb 2007 08:06:00 GMT

Problem

When you try to connect to a Windows Server 2003 box using Remote Desktop Connection (mstsc), you get an error message that you can not connect; because the number of connection exceeded the limits.

The number of available connection sessions through Remote Desktop Connection are limited to two (active or disconnected), and inorder to connect an empty session must be available to you. One of the mistakes is to exist the Remote Desktop Connection tool by clicking the X at the top right corner; this will disconnect the session, however it will not terminate it. So be sure to exit the RDC by using the log off command.

Solution

Run the Remote Desktop Connection tool with the /console switch. This will allow you to connect to Session 0 (Console). Please note that the documentation incorrectly state that you can use the /console switch with Windows Server 2000 boxes, this is incorrect and it's only valid with Windows 2003 Server boxes (KB#311926).

Example: mstsc /console

Typically after you login using the /console switch, you would terminate the idle sessions, you can do this using the Terminal Services Manager.

SQL Server More Secure Than Oracle Database

Maher Al-Jendasi — Sat, 25 Nov 2006 01:37:00 GMT

On a white paper entitled (Which database is more secure? Oracle vs. Microsoft) published on November 21, 2006, security researcher David Litchfield of NGS Software compare the security holes targeting two RDBMSs: Oracle (v8, v9 and v10) and Microsoft SQL Server (7, 2000 and 2005). The comparison based on externally reported flows.

The report shows that Microsoft has patched 59 security hole in its SQL Server 7, 2000, and 2005 during the period from 2000 to 2006, while Oracle has patched 233 security hole in its Oracle 8, 0 and 10 on the same period.

You can download and read the details in the whitepaper, or in NGS Software site

'Sys' is undefined When Upgrading to ASP.NET AJAX Beta 2

Maher Al-Jendasi — Sat, 11 Nov 2006 01:08:00 GMT

When you upgrade your site to use the ASP.NET AJAX Beta 2, you must add a new HttpHandler in the web.config file. Under the <httpHandler> element in the web.config, add the following handler:

<add verb="GET" 
  path="ScriptResource.axd" 
  type="Microsoft.Web.Handlers.ScriptResourceHandler" 
  validate="false"/>

Otherwise you may receive 'Sys' is undefined error message

Using External JavaScript File with ASP.NET Ajax Extension Beta 2

Maher Al-Jendasi — Thu, 09 Nov 2006 12:15:00 GMT

I have upgraded an Ajax-enabled ASP.NET site that I'm working on to use the latest ASP.NET AJAX Extenstion Beta 2. My site use external javascript files that is being registered with the ScriptManager, like:

<asp:ScriptManager runat="server" ID="ScriptManager1">
    <Scripts>
        <asp:ScriptReference Path="~/scripts/script_file1.js" />
        <asp:ScriptReference Path="~/scripts/script_file2.js" />
    </Scripts>
</asp:ScriptManager>

After upgrading to Beta 2, any functionality that needs to use functions inside those files, was giving errors?!

After reading the "Changes between the ASP.NET AJAX (“Atlas”) CTP and the Beta 2 and RTM Releases", I come to know that every external Javascript files that being referenced from ScriptManager must have a call to Sys.Application.notifyScriptLoader; this will notify the Sys.Application that the script files has been downloaded to the client computer, so for each external .js file add the following snippet:

if(typeof(Sys) !== "undefined")
  Sys.Application.notifyScriptLoaded();

Another solution that Alessandro Gallo has blog it is to add the following snippet to the end of each .js file:

if(Sys && Sys.Application) {     
    Sys.Application.notifyScriptLoaded();
}
