Description of the Project Server 2010 hotfix package (Wosrv-x-none.msp, Pjsrvwfe-x-none.msp, Osrv-x-none.msp): August 31, 2010

This article describes the Microsoft Project Server 2010 issues that are fixed in the Project Server 2010 hotfix package that is dated August 31, 2010.

Issues that this hotfix package fixes

  • The New-SPProjectWebInstance cmdlet does not work together with the host header when a site collection already exists.
  • Project Server administrators now can resolve user names by using email addresses. For example, depending on how the claims providers are configured, the user logon account can be entered and validated as an email address such as on the Edit User page.
  • After you provision a Project Web Access (PWA) site, the queue service process restarts unexpectedly. This causes the interruption of the queue on other PWA sites.
  • The queue service may consume large amounts of memory, such as several gigabytes (GB), when there are hundreds of PWA sites in a farm.
  • If users cannot be resolved in Active Directory because of intermittent connectivity issues, the users are deactivated.
  • Consider the following scenario. You apply the hotfix package that is described in Microsoft Knowledge Base article 2075990. You connect the Project client to Project Server 2010 and use manually scheduled tasks. Then, you update the % complete column on a manually scheduled task in the project. In this scenario, the baseline work value is cleared from other manually scheduled tasks unexpectedly.
