Run As Different User - Authentication Failed

Question

Windows 7 x64 on a domain....not a new build...no GPOs have changed.  When I try to run any program (CMD, links to apps, ADUC, MMC, etc.) with Run as different user it fails with "Authentication Failed" no matter which account I use.  Seems like an obvious issue, but it's not.

I can RDP to servers, with the same elevated account, using the same password, and it goes right through.  While on that server I can use Run as different user, on any application, without any problems at all.  I've changed the pwd to that account as well, just for the heck of it.  Here's the other weird part..... If I choose Run as different user and use the very same credentials I used to login to the machine (launching CMD, for example) it still comes back with 'Authentication Failed'......makes no sense!  A CMD prompt will open right up if I just double-click it, however.

It's worked 1000x before without any problems at all and I've never seen this happen in my life, until 2 days ago.  No GPO changes, no movement of my account or workstation to new OU's, account isn't locked or disabled, etc.  To be honest, I don't even know HOW I would purposely create a situation like this outside of disallowing 'Secondary Logon' via GPO, which wouldn't even show the secondary choices when right-clicking.

The weirdest part is that the error message is "Authentication Failed", rather than something like 'Access Denied' or something like that.

Hi,

To further assist you with your concern, please answer the following questions:

1. Does it happen on all of the programs and applications in your computer?
2. Are you logging in as an administrator?
