Virus Hunting: Track and Report Server Attacks Quickly and Easily with the .NET Networking Classes

Posted By:      Posted Date: August 21, 2010    Points: 0   Category :ASP.Net

To help stop the spread of worms, viruses, and other hostile activity, it is important to track down and report the servers used in these attacks along with those used to send spam. Many Web administrators, however, don't take the time to track them because the manual process can be quite cumbersome. The Microsoft .NET Framework comes to the rescue with several networking classes, including the Dns class and the TcpClient class, that abstract away the complexity of performing DNS and WHOIS lookups. These classes make it easy to create a simple, straightforward ASP.NET-based utility for performing these lookups and automating this very important task.

Virus Hunting: Understand Common Virus Attacks Before They Strike to Better Protect Your Apps


Developer's machines can often be more vulnerable to viruses than the average corporate user because of their more frequent access to remote machines and shares, and the differing administrative privileges they maintain across mutiple machines. Reliance on antivirus software is fine as a first line of defense, but you need a basic arsenal of skills for securing the executables on your system and coping with viruses on your own. This article reviews proactive methods you can use to defend yourself against malicious executable code in resources, component libraries, scripts and macros, as well as how to avoid a handful of other potential vulnerabilities.

A connection could not be made to the report server http://localhost/ReportServer.



  • I created a Report using Business Intelligence Studio. Its working working well, i can able to view records. But when i try to deploy the report an error occurs specifying that "A connection could not be made to the report server http://localhost/ReportServer. (Microsoft Report Designer)".
  • I open the IIS 7 and find out virtual directories "Reports" and "ReportServer" are available.

Data Points: Report Controls in SQL Server 2005 Reporting Services


Reporting has always been one of the dark arts of development. The tools typically seem to do just enough to get you to a certain point, then leave you to find workarounds to solve more complex issues.

C++ and ATL: Use ATL Server Classes to Expose Your Unmanaged C++ Code as an XML Web Service


Throughout this issue, you'll read all about the promise of Web Services and how the .NET Framework enables Web Service development. Many people will also be building their Web Services atop C++ code and frameworks like ATL Server, particularly when performance is paramount. In this article, the authors show how fully functional Web Services are built using ATL Server and Visual Studio .NET. Beginning with unmanaged C++ classes, they add ATL attributes that make the code work over HTTP.

Cannot export from a Report in SharePoint integrated mode in a server hardend environment


We have installed Reporting Services 2008 integrated with MOSS with SQL Server 2008 on a 64 bit platform.

The environment has worked fine in test (but the servers are not hardend).

With the production environment, any attempt to export from a report into another format (eg excel, tiff etc) results in an unexpected error within SharePoint requiring closing the browser and reopening.

There are no details behind the error. We can also find no traces of the error within any of the logs (SharePoint, Reporting Services, Windows event log etc)

When the report is opened directly from Reporting Services (ie http://servername:8080/reportserver) the report exports fine. Similarly, if the report is opened directly from Report Builder 2, or through opening Report Builder 2 from SharePoint there is no issue. This issue only happens when the report is invoked directly through SharePoint.


We can only assume that this issue has something to do with server hardening/UAC as we have

Cannot add SQL Server 2008 R2 Report items to SharePoint Server 2010 document library

Using account which is the primary parent site administrator, can upload RDS and RDL files to the document library (however, cannot open report). User is also a domain admin with SA on the database instances. Cannot add Report Data Source with "New Document" icon. The permissions granted to user '[domain]\[user]' are insufficient for performing this operation. Under "Site Settings", "Managed Shared Schedules" fails with same error. Attempting to deploy from BIDS results in the same permissions error. Sharepoint Server 2010, Report Server 2008 R2. RS and SP databases hosted on remote server (SQL Server 2008 R2). All connections (SharePoint services, RS services, users) except SQLAgent authenticating to remote SQL Server with Kerberos (all SPNs look correct). Single site, site collection "/". Document directory called "Reports". Windows Integrated Security (Negotiate). How would I troubleshoot/solve problem?

Report server cache vs RAM

Hello, When report server executes a huge report(or any small or big report), it consumes some amout of RAM available on the server box. Once the report is completely executed, does it releases the RAM that it used for report execution? Does RAM goes to the original level after complete report execution? When the report is cached, does this cache memory something different from the available RAM on the server box? If so, from where this cache memory comes from? Regards.

Moving a Copy of SQL Report Server 2005 and Upgrade to 2008

Hello, We have SQL 2005 Report Server in a Windows 2003 64 bit server box. We want to create a copy of this report server database somewhere in the domain, so that we can access it for a different purpose. My question is, will there be any complications with this? I'm thinking about the encryption key that's needed to access the database. If we are successful with this, we might also want to upgrade to SQL 2008. Thanks for your help,   Elizabeth K.
