Summary

Along with Microsoft's announcement of the SHA-1 deprecation policy, they also provided information that the Windows 2003 Server can no longer use the SHA-1 certificate in SSL connection, but SHA-2 instead.

When Windows 2003 tries to establish an SSL connection to SPS URLs with a SHA-2 certificate, the following error may occur and cause connection failure, which can be observed in the ofcdebug.log:

2016 09/26 10:43:57 [0d5c : 0d60] (00) (W) [cgiShowClientAdm][cgiShowClientAdm.exe][CWinHttp::WinHttpRequest] Error code 12175 - [libWinHttpWrapper.cpp(253)]

This article discusses how to solve this error.
