SYMPTOMS
When the POST method is used from an HTML form to upload large amounts of data, your server may intermittently generate a "HTTP/1.1 500 Server Error" on the browser when SSL and NTLM are both enabled on the server connection. This error only occurs if the Web site is configured to use SSL and has NTLM authentication required for the connection. This problem has been reproduced using ASP pages and with custom ISAPI DLLs.

RESOLUTION
To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, please see the following article in the Microsoft Knowledge Base:
