The K2.net Workspace reports an error when a user enters the web site.

If you receive an error on the K2.net Workspace, you first need to turn off the default error handling to determine the cause of the error, to do this:
•  Find the “Web.config” file in your Worklist folder. Usually it resides in: “<drive>:\program files\k2.net 2003\K2WS\Workspace”
•  <customErrors defaultRedirect="Error_Page.htm" mode="Off" />
•  It is case sensitive, so the Off must have a capital ‘O’
•  When you try again, the error description will appear instead of the custom error page.
 
If your error is a “permissions denied” error, you need to check for general permission problems on the ASPX temporary directory: (“<drive>:\windows\microsoft.net\framework\<framework version>\temporary asp.net\****”), however, first check the other Knowledge Base and Forum articles to determine if the cause may be related to one of the problems outlined in these articles:
 
•  KB000011
•  KB000019
•  KB000068
 

If this is not the case, then a simple test may reveal this as an IIS configuration issue. Try to create a very simple ASPX web page with nothing on it but a “Response.Write” method:

VB.NET

Response.Write(“Testing”)

C#

Response.Write(“Testing”)

If you experience the same error when executing this code, the likelihood is that there is nothing wrong with the K2.net 2003 Workspace, just IIS. Execute the following in a command window (Start | Run | Cmd ) – you will need to be a local administrator to accomplish this:
“aspnet_regiis –I”

What this will do is install this version of ASP.NET and update scriptmaps at the IIS metabase root and all scriptmaps below the root. Existing scriptmaps of lower version are upgraded to this version.

After accomplishing this successfully, try the K2.net Workspace again.
