## Symptoms

- * DNS resolving with Windows 8.1 VPN plugin and Capsule VPN for Windows 10 does not work if no DNS suffixes have been configured in the 'Gateway Properties \> VPN Clients \> Office Mode \> Optional Parameters'
* DNS resolving works well with other clients such as SNX or Endpoint Remote Access variants.

## Cause

Although in many cases DNS suffixes are used for convenience only and are not mandatory for the purpose of resolving, evidently the Windows 8.1 Plugin and Capsule VPN app for Windows 10 can only resolve host names whose domain suffix is configured in the Office Mode Optional Parameters.
