Clearing the Cache in SharePoint

In case you encounter the Update Conflict Error:

1. Stopping wss timer job, Saving Copy of the cache.ini file from C:\Documents and Settings\All Users\application data\Microsoft\SharePoint\Config folder. Clearing all the .xml files from the location except cache.ini but Edit the cache.ini to have value 1. Starting the timer job

2. Rerun the Sharepoint technology wizard on the server.

3. If all above doesnt work, you may run the configuration wizard. select the option to disconnect the server from server farm and revert back again at next step (so you actually do not disconnect). Selected the option as not to disconnect from server farm and ran the wizard successfully.
