We have been using the combination of Window XP, Cisco VPN, and Client Access 5250 Emulation for our remote users to connect with our iSeries (V5R4) with success for years.
We just recently had our first remote user with a new Windows 7 Professional 32 bit machine, using Cisco VPN (5.0.01.0600) and Client Access 5250 (V5R4 mod level 0 Service level SI37892) attempt a VPN connection the iSeries. The connection is made without issue, until the initial program found on the user profile is ran and then the session is disconnected receiving the CPF5140 error message. The program being launched by the user profile has been around for years and unchanged as well.
Windows 7 is the only new variable in the equation. Any help solving this is greatly appriceiated, since we cannot get Windows XP anymore.
