Security :: A Number Of Events Being Logged On Windows Server?

Apr 30, 2010

I've noticed a number of events being logged on our Windows server, coming from an Asp.net application. I wouldn't know where to begin troubleshooting this problem, but the basics are this:

- Windows Server 2003 Standard Edition (NLB)
- Asp.net 3.5 App
- Oracle 10g DB
Event ID: 1309
Event code: 3005
Event message: An unhandled exception has occurred.
Exception information:
Exception type: CryptographicException
Exception message: Padding is invalid and cannot be removed.

The second last line here is why I posted in the security forum. The page that it's coming from is webresource.axd

Stack trace: at System.Security.Cryptography.RijndaelManagedTransform.DecryptData(Byte[] inputBuffer, Int32 inputOffset, Int32 inputCount, Byte[]& outputBuffer, Int32 outputOffset, PaddingMode paddingMode, Boolean fLast) [code]....

VS 2008 - No Error Is Generated And No Entry Is Logged In Windows Event Viewer On Server

Sep 9, 2011

i made an upgrade to an existing application (still developed by me), while testing on my development machine, everything worked fine. After migrating to a Test Server(windows 2003 server), users can not test the application, it periodically crashes their session and redirected them to the login page (Forms Authentication). No error is generated and no entry is logged in the windows event veiwer on the server. I also noticed this also happens when they try to access a particular page in the application.

The page contains 50 instance of a user-control. Each of the user-control contains 8 textboxes, 2 labels,1 hidden field and 12 asp.net validation controls. I tried saving a copy of this page from Internet explorer (IE8) on my development machine,its about 2.2MB in size.What may be wrong and what tracing tools can i use on my development machine (since it generates no errors). How can i also reduce the size of the page (noting that the asp.net validation controls generated alot of HTML codes)

Want A Certain Number Of Queries To Run Only Once Per Session, After The User Logged In?

Jan 30, 2011

I'm building a web application: some pages will be accessible by non logged-in users (demo and sign-up pages) and others will only be accessible by logged-in users (actual application). In the global.asax file, I'm currently handling the session start event by loading some variable from a query that's based on the UserID. What will happen when a non-logged in user looks at a page? I guess my question is really about how to handle the session start event when it's a logged-in user, when it's not and when a user logs in. I want a certain number of queries to run only once per session, after the user logged in.

Tacking Number Of Users Logged In Over A Time Period - Database Design?

Nov 12, 2010

In our application, we store the most number of users online. We do this by tracking what page each user is on currently and upon login, delete users who have been inactive for X minutes and then take a count of the users online, overwriting the most number online if this is higher.

How can we change this to track the number of users online over a time period, so we can look at a line graph of the number of users online. I guess we'll need a cron to run every 1/2/5/10/20/30/60 minutes to track the number online? Then how would be store this data, the table would get very large. I would think the likes of Statcounter/Analytics would have a better way of storing this data.

Security :: Running Application Under The Security Context Of The Logged In User (LDAP Authentication)

Mar 17, 2011

We are using membership provider for LDAP authentication. It is working as it should.

But what all configuration settings I have to do so that
all the future requests to this application run under the security context of the Logged in user account not through the some default user set in IIS.

We need to have this working because all the permissions on the database are based on the logged in user.

We are using form authentication for LDAP authentication. And having impersonation = true in web.config.

Asp.net - Why Does Visual Studio Add Number When Create Page Events In Codebehinds

May 13, 2010

When writing up a codebehind in Visual Studio for ASP.NET web forms applications, I often use the dropdowns at the top of the window to autogenerate page event handlers (e.g. Page_Load, Page_PreRender). I've noticed that sometimes Visual Studio likes to add numbers to these function names like "Page_Load1" or "Page_PreRender2".

I added the debug="true" attribute to the web.config file to get the line where the exception is lauched. The line identified in my code is an End If and the code just before seems benign :
