Network Access and F5 BIG-IP Edge Client (Windows)

I have found your experience to be the "norm" after going through several upgrades from 10.x to 11.2 to 11.3 to 11.4.1 HF2... client side issues are a nagging problem... we have over 2000 clients and a wild guess would be a 1-2% failure rate on clients after upgrades. re installing 20-40 clients after each upgrade is no fun. Support has been unable to provide much assistance other than recommending remove all F5 items and re installing.. in extreme cases they recommend re imaging the entire workstation.
