SYMPTOMS

When you try to log on to Microsoft Project Server with Microsoft Project Professional or Microsoft Project Web Access, you may receive the following error message:
Microsoft Project was unable to log you on at this time because the Microsoft Project Server database cannot be accessed. Please try again later or check with your Microsoft Project Server administration. (5001)
When you try to install Microsoft Project Server, you may receive one or both of the following error messages:
Microsoft Project Server 2002 Setup Error 1904. Setup cannot register module C:\WINNT\System32\MSXML3.DLL. If you click Cancel or Ignore, run Setup again and reinstall or repair your Office installation.
Microsoft Project Server 2002 Setup Installation ended prematurely because of an error.

CAUSE

This behavior may occur if any of the following conditions are true:
  • The passwords for the MSProjectUser and MSProjectServerUser SQL Server accounts (or the accounts performing those roles) do not match the accounts that Microsoft Project Server has stored in the registry.
  • The MSProjectUser and MSProjectServerUser accounts (or the accounts performing those roles) are corrupted.
  • The application server that runs Microsoft Windows 2000 (any service pack) cannot successfully initiate a connection to the database server that runs Windows Server 2003. Because Microsoft Windows Server 2003 includes MDAC 2.8, for the application server to successfully initiate a connection to the server, it requires matching MDAC components.

    To check server components, visit the following Microsoft Developer Network (MSDN) Web site:

    http://msdn.microsoft.com/library/default.asp?url=/nhp/Default.asp?contentid=28001860

    To download MDAC 2.8 on to your application server, visit the following Microsoft Developer Network (MSDN) Web site:

    http://msdn.microsoft.com/library/default.asp?url=/nhp/Default.asp?contentid=28001860

Note The version of the MDAC on the server is likely MDAC 2.7 SP1 or earlier.
