Cannot Generate SSPI context, strange?

Posted By:      Posted Date: September 10, 2010    Points: 0   Category :Sql Server
I recently put into affect some applications for data entry and searches connecting to a SQL 2008 database. When a user logs in and starts the application they are able to enter data. The data save to the database fine, then randomly we get crashes saying: "Unhandeled exception while running screen" its a SSPI error.... strangley enough if i log out and log back in, it again allows the program to enter into the database.... but surely enough after a few entries it gives me the error again. We are a small company, and the server we run AD on is pretty slugish, so loging out and back in... can to say the least take some time. This makes our productivity alot lower. If anyone has a fix or has any suggestions id gladly take them. Both Servers we use have Server 2008R2.

Here we go, "Cannot generate SSPI Context"

When trying to register a SQL Server in my SSMS on my desktop, I get the error.  My AD account is in the SQL Server as sysadmin.  When I go to the box, I can connect from SSMS with my AD account.  I dont see how its DNS, cause I can ping it by name from my desktop.  Any other ideas? remote connections are allowed enabled TCP/IP and Named Pipes In the server Event Viewer>Security, I get Failure Audit, user: system, Reason: Unknown user name or bad password BUT, I also get a Success Audit with my domain account.  

Cannot generate SSPI context. (.Net SqlClient Data Provider)


I have upgraded SQL SERVER 2000 standard edition server to SQL server 2008 with SP1 standard edition. No errors noticed. OS is Windows server 2003 with sp2, Service accounts are configured using domain user account, and mixed mode authentication is enabled.

Both windows and SQL authentications are working fine from the local (server), able to access all SQL server resources.

Server is accessible remotely using SQL authentication, but unable to connect with windows authentication, though user has local admin and SQL admin rights on the server.

Let me know any solutions for this. Appreciate your support

Usually we do this by performing the action under RunWithElevatedPrivileges method and updating the listitem using SPListItem.SystemUpdate() method (see here). but this approach has its own flaws like (RunWithElevatedPrivileges will run under system account, we cannot use SystemUpdate for SPSite,SPWeb,SPList, since it runs under system we will "CreatedBy" by as SystemAccount).

Cutting Edge: Context-Sensitive PictureBox Controls


Great ideas are timeless. A long time ago in Microsoft Systems Journal Paul DiLascia demonstrated a neat trick to display context-sensitive tooltips floating over pictures. As the user moved the mouse over the picture, the tooltip control updated its text to reflect the name of the pointed figure.
