SYMPTOMS
Consider the following scenario:
- You have a Microsoft Windows Server 2003-based client computer.
- On this computer, you use an application that calls the CryptQueryObject function to decode an embedded PKCS7 certificate.
In this scenario, a temporary file of 0 bytes is created in the %windir%\Temp folder. This temporary file is not deleted when the CryptQueryObject function finishes its task. Additionally, when the number of temporary files reaches about 65,000, the call to the CryptQueryObject function takes longer than expected to finish.
Note %windir% represents the path of the Windows system folder. Typically, this path is C:\Windows.

WORKAROUND
To work around this problem, manually delete the temporary files before the number of temporary files reaches 65,000.
STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
MORE INFORMATION
This problem is more apparent when the CryptQueryObject function is called either directly or indirectly from a server application through some intermediate layer. When the number of temporary files reaches 65,000, client computers experience significant delays. A known indirect caller of the CryptQueryObject function is the constructor of the System.Security.Cryptography.X509Certificates.X509Certificate2 managed class.
Technical support for x64-based versions of Microsoft Windows
If your hardware came with a Microsoft Windows x64 edition already installed, your hardware manufacturer provides technical support and assistance for the Windows x64 edition. In this case, your hardware manufacturer provides support because a Windows x64 edition was included with your hardware. Your hardware manufacturer might have customized the Windows x64 edition installation by using unique components. Unique components might include specific device drivers or might include optional settings to maximize the performance of the hardware. Microsoft will provide reasonable-effort assistance if you need technical help with a Windows x64 edition. However, you might have to contact your manufacturer directly. Your manufacturer is best qualified to support the software that your manufacturer installed on the hardware. If you purchased a Windows x64 edition such as a Microsoft Windows Server 2003 x64 edition separately, contact Microsoft for technical support.
