Hello I just updated few weeks ago a TZ100W, a TZ205 and a NSA-240 from 5.8.4.1 to 5.9.1.1-39o and after that they have all the same problem all users with XP, VISTA and WIndows 2003 Server stopped to connect to the Sonicwall using NETextender, I tried version 7.5.216 and 7.5.225 without success. I receive the error : The server is not reachable. For users with windows 8, 8.1 and 10 it works fine. I tried search on internet but didn't find anything!
If anybody could help me I would be very happy!
In the debug I see this the following:
