SYMPTOMS
On a computer that has multiple processors, you receive the following error message when you request a Microsoft ASP.NET page:

Server Application Unavailable

You may also receive the following error message in the browser or in the Microsoft Internet Information Services (IIS) event log:

HTTP 500 - Internal server error



CAUSE
This problem occurs if the following conditions are true:
 * You use the /BASE switch to compile a DLL in Microsoft Visual Studio .NET 2003.
 * You set the address location to 0x33A20000.



RESOLUTION
To resolve this problem, obtain the latest service pack for Microsoft .NET Framework 1.1. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

Hotfix information
Important This hotfix contains the following two types of packages:
 * A Microsoft Windows Installer package
 * An Optional Component Manager (OCM) package

If you use Microsoft Windows Server 2003, you must specify that you require the Windows Server 2003 (OCM) update. If you use an operating system that is different from Windows Server 2003, you must use the Windows Installer package. For Windows Server 2003, Windows File Protection monitors the .NET Framework 1.1 files.

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section. This problem was first corrected in Microsoft .NET Framework 1.1 Service Pack Service Pack 1.



MORE INFORMATION
The order that the DLLs are loaded in affects this problem. If the DLL that uses the 0x33A20000 address space is loaded in a process after ASP.NET is invoked, ASP.NET continues to work correctly.

This problem may also occur if you use ASP.NET with other Microsoft products. For example, the problem may occur if the following conditions are true:
 * You use Microsoft Content Management Server (MCMS) 2002 sites in the same application pool as ASP.NET.
 * You visit the MCMS sites before ASP.NET is invoked.

Although you can rebase the DLL, rebasing the DLL may not be a reliable solution.
