ASP WebClassRuntime and Windows2000 SP4 Problem

[Andy \(ABA\)]

Hi All
I have different WebApplications running on Windows2000 Servers without
problems since years now. Since the Administrators recently started to
install Windows 2000 Service Pack 4 the WebApps doesn't work anymore. The
First request of a page returns the Error "An internal exception has
occurred" thrown by the WebClass Runtime, all other page requests doesn't
receive any response at all (IE seams to "hang").

I found two Knowledge Base Articles (KB821546
(http://support.microsoft.com/default...b;en-us;821546) and
KB304071 -
(http://support.microsoft.com/default...en-us;304071)), but it
doesn't help me to solve the Problem (It is no Security or Language specific
Problem as described there).

Has anyone a solution for that problem? Is there a newer WebClass Runtime
(MSWCRUN.dll) than 6.0.88.4 contained in VB6 SP5?

Thanks
Andy
