SYMPTOMS
On a computer that is running a 64-bit version of Microsoft Windows Server 2003, you cannot see certification authority (CA) Web enrollment pages. You experience this problem when the computer is also running Microsoft Windows Server Update Services (WSUS). You may also experience this problem when the computer is running another service that requires a 32-bit version of Microsoft .NET and that causes Microsoft Internet Information Services (IIS) to run a 32-bit work pool.



CAUSE
This problem occurs because the CA Web enrollment pages require a 64-bit work pool. WSUS, and some other services, cause Microsoft IIS to run a 32-bit work pool.



WORKAROUND
To work around this problem, disable ASP.NET in ISAPI filters. To do this, follow these steps:
 * 1) Click Start, click Administrative Tools, and then click Internet Information Services (IIS) Manager.
 * 2) Expand , right-click Web Sites, and then click Properties.
 * 3) Click the ISAPI Filters tab, select the filter that has a filter name that starts with &quot;ASP.NET,&quot; click Remove, and then click OK.

Note This workaround causes services that use Microsoft .NET to no longer function.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
