Hey John,

It's difficult to understand stack traces without some context. It would be helpful if you could provide readers an idea of what you were doing in TDP before the exception occurred.

Otherwise, I'll note the obvious from what I see. Did your system get re-imaged, or perhaps something happened to prevent you from accessing your
C:\Users\john.breitmaier\AppData\Local\Temp
folder?

BTW, TDP 6.0 is available for download, so it would be worth it to update. Else, might want to open a Support ticket with Quest.

Thanks for the reply. It worked all day yesterday, no issues. All I did today was to execute it and these errors appeared, not allowing me to connect to anything. Everyone on my team is having the same issues.

Thanks for extra intel. I wonder if you can check with your sysadmin to see if any changes (with regard to OS, app, or folder security or permissions) have taken place... especially if everyone is experiencing the same issue.
