This issue is addressed on Bug ID#144622 and fixed in ProxyClient 126.96.36.199 LA.
ProxyClient 188.8.131.52 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.
