Netsh.exe winhttp show proxy
On x64 based systems, make sure to execute Netsh.exe from C:\Windows\SysWOW64\ folder
Example on Windows XP Client:
In case that the configured "Proxy Server(s)" would not be valid anymore, please remove it from the WinHTTP proxy configuration or completely switch to direct access mode via "Proxycfg.exe -d" to bypass all configured WinHTTP proxy servers.
Configured WinHTTP proxy settings can also be verified via the following Registry Key: HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\Connections\WinHttpSettings
The SafeGuard Enterprise Client should be able to communicate with the SafeGuard Enterprise Server now.
