About 2-3 months ago I started getting a "Connection Attempt Failed - please try again" message when trying to connect to our ASA5512. Oddly enough I only get this message from Windows PCs ( Win 7 ). All Macbooks are still able to connect without a problem. Something seemed to have changed because we had no problems connecting in the from Windows or Mac devices in the past.
I was thinking that there may be an issue with Explorer 10 that is causing the problem because all of the OS X Devices continue to connect withoout a problem.
Does anyone have experience with the issue?
Any suggestions on where to start on finding a solution?
