We have seen a number of issues in regards to the security update MS07-040 This is not meant to be an inclusive list of issues, but these are some of the problems we have seen and what the resolution was for each.

Problem 1

Getting an exception after updating to MS07-040 when using SSL (TLS)

Unhandled Exception: System.Net.WebException: The underlying
connection was closed: Could not establish secure channel for
 SSL/TLS. ---> System.ComponentModel. 
Win32Exception: The message received was unexpected or
 badly formatted 
--- End of inner exception stack trace --- 
at System.Net.HttpWebRequest.CheckFinalStatus() 
at System.Net.HttpWebRequest.EndGetResponse(IAsyncResult asyncResult) 
at System.Net.HttpWebRequest.GetResponse()

Root Cause:

The reason for the client to have worked all the while before applying the security update, was because by default, the .Net 1.1 framework only supported the SSL v3 protocol. The TLS protocol is disabled in the .Net 1.1 framework. After applying the above patch, the .Net framework 1.1, enabled the TLS protocol and since it is the latest SSL protocol specification, you suddenly faced the above error.

The error you faced was because the SSL Accelerator card was only configured to handle SSLv3 traffic. You needed to explicitly enable the TLS specification on the Accelerator card to make it compatible with the Client request.

Resolution:

Enable the TLS specification on the accelerator card to make it compatible with the TLS Client. If this is not done, the card responds back with a Fatal Error indicating that it cannot understand the TLS protocol.

Problem 2

Getting unprintable characters in client-side script after installing the patch
