This issue is addressed on Bug ID#144622 and fixed in ProxyClient 220.127.116.11 LA.
ProxyClient 18.104.22.168 has been released on the BlueTouch internal download site:
This is a Limited Availability (LA) release that addresses the following customer request:
- DFS shares are not shown after upgrading to PxC 3.2.2.x from 3.2.1.x B#144622
After downgrading to ProxyClient Ver. 3.2.1.x, the DFS share folders can be seen and it is one of the workarounds.
