- Doing an IISReset solves it but it could appear again

- Go to IIS Manager, select the Application Pool for your web application and click Advanced settings, change the value for "Load User Profile" to "true"

The SPListItem.CopyTo() method doesn't seem to work on a custom list or custom properties. When called, CopyTo() returns the error "Source item cannot be found. Verify that the item exists and that you have permission to read it."

Solution: Dorrit Riemenschneider posted this solution in German, Dorrit provides source code you can cut and paste, look for the section in italics near the end of his post: https://www.communardo.de/techblog/2008/01/08/sharepoint-listenelement-splistitem-in-eine-andere-liste-kopieren/

SPListItem offers a CopyTo(destinationUrl) method that doesn't work with a custom list, insteadyou get the exception: "Source item cannot be found. Verify that the item exists and that you have permission to read it."

Dorrit wrote a method that takes the SPListItem and destination list as parameters, and returns a reference to the new list item.

First the method adds an item at the target location. Then it steps through and copies each field. Note that we can't copy read-only fields, and attachments require special treatment. Once complete, the target is written with Update() and a reference to the destination element is returned.

 Imagine a tool that you could use to:

•           Input a few key facts about users, user needs, business requirements, and organizational resources 

•           Build a topology model based on this input

•           Run simulations that show the impact of this topology

•           Generate a summary report that will help you evaluate alternatives

The SharePoint Capacity Planning Tool comprises models of both Microsoft Office SharePoint Server 2007 (MOSS) and Windows SharePoint Services 3.0 (WSS) that allow you to explore the necessary infrastructure for either deployment based on usage requirements. This tool uses the System Center Capacity Planner 2007 (SCCP) as an engine to provide for data collection, visualization, simulation, and report writing. The tool can be used in pre-sales and feasibility studies of a deployment project to give you a rough estimate of hardware requirements.

The tool is able to consider variations in usage, size of installation, networking technology, scale, and availability.

The tool can generate estimated performance metrics based on a simulation and provide useful Visio schematics of the proposed deployment to be included in documents and proposals.
