Error messages when you access a Microsoft Project Web Access page that contains grids (832588)

SYMPTOMS

When you connect to Microsoft Office Project Server 2003 by using Microsoft Office Project Web Access 2003, and you access Project Web Access pages that contain grids, you may experience one or more of the following symptoms:

When you click Tasks or click Projects, you are redirected to the Home page.
When you click Resources, you receive the following error message:
An error occurred while trying to access the resources stored on the database. Either there are too many resources, or the project server may not have the correct DSN configuration. Contact the server administrator.
When you click Manage Users and Groups, you receive the following error message:
Line:1756
Char: 3
Error: Internet Server Error: Object/module not found.
Code: 0
URL: http://ServerName/projectserver/Admin/Sec_Users.asp

CAUSE

This behavior may occur if any one of the following conditions is true:

The Application pool identity on MSADC virtual directory for Project Server is set to an specific Domain user account.
You install Project Server 2003 before you install and configure Microsoft Windows SharePoint Services.

In this situation, the MSADC path is not excluded from the Windows SharePoint Services name space.
The port that is used for requests to the Remote Data Services ISAPI Library component (Msadcs.dll) is blocked by a firewall.

WORKAROUND

To work around this behavior, use one of the following methods.

Method 1: Change the application pool identity for MSADC

Click Start, point to All Programs, point to Administration Tools, and then click Internet Information Services (IIS) Manager.
Expand WebServer (local computer), expand Web Sites, expand Default Web Site, expand MSADC, and then find the application pool that is configured for MSADC.

Note WebServer is the actual computer name that is assigned to your Web server.
Change the application pool identity to any predefined account, such as the network service, the local service, or the local system for the MSADC virtual directory.
Restart IIS to recycle the application pools. To do this, follow these steps:
1. In the Internet Information Services (IIS) Manager, right-click WebServer (local computer), point to All Tasks, and then click Restart IIS.
2. In the What do you want IIS to do box, click Restart Internet Services on WebServer, and then click OK.

Method 2: Use SharePoint Central Administration to exclude the MSADC path from Windows SharePoint Services

On the server that is running Windows SharePoint Services, start SharePoint Central Administration.
On the Windows SharePoint Services Central Administration page, under Virtual Server Configuration, click Extend or upgrade virtual server.
On the Virtual Server List page, click complete list.
On the Virtual Server List page, click the name of the virtual server where Windows SharePoint Services is configured. For example, click Default Web Site.
On the Virtual Server Settings page, under Virtual Server Management, click Define managed paths.
On the Define Managed Paths page, in the Add a New Path area, type the MSADC namespace that you want to exclude from Windows SharePoint services. For example, type /MSADC.
Under Type, click Excluded path, and then click OK.

To avoid this behavior, install and configure Windows SharePoint Services before you install Project Server 2003.

Method 3: Open the port on the firewall that is blocking requests to the Remote Data Services ISAPI Library component (Msadcs.dll)

Important When you open ports in your firewall, you increase the chance that other programs may gain access to your computer through those ports. Because of this, we recommend that you carefully consider your network security requirements before you open ports in your firewall.
