    Good day,

      While trying to create a new project we receive the following error after we have completed the admininstration of the project and it is going to login into the backend. The screen shows up to login but when I submit the info is when I get the error. Sitefinity is running on Windows server 2003, IIS 6. We have created other projects in the past with no problem.  This is the only project in the Sitefinity Project Manager as we removed all other projects we did have.  We are using project manager from an XP machine. In the past we have no problems running Project Manger from the xp machine. Due to company policies we cannot run any browser on the server so we must use the project manager from a mapped network drive. Never has been a problem previously though. Connecting to a new database.
