SYMPTOMS
When you try to update the Microsoft Antigen 9.0 for Exchange scan engines, one or more engine updates may be unsuccessful. In this situation, you experience the following symptoms:  The engine update operation times out. Information that resembles the following is logged in the %ProgramFiles%\Microsoft Antigen for Exchange\ProgramLog.txt file:

&quot;INFORMATION: Attempting to download the Sophos scan engine package from http://antigendl.microsoft.com/antigen/x86/Sophos.&quot; &quot;ERROR: UpdateException: GetFileCommand failed on sophos_fullpkg.cab. (0x00002ee2) The operation timed out. WinHttpClient failed while receiving a response.&quot; &quot;INFORMATION: The Sophos scan engine for Antigen has been rolled back





CAUSE
This problem occurs because of the default time-out value for calls that the WinHTTP process makes. By default, any calls that the WinHTTP process makes have a 30-second time-out value. Therefore, during periods of high network activity, or in an environment that has insufficient bandwidth, the Antigen 9.0 for Exchange engine update process may time out before the engine download operation has finished.
