I am trying to login to one of our servers, using Remote Desktop Protocol. I have to connect to VPN to connect through RDP. I was able to connect few days ago. Suddenly I was not able to connect to it. I was getting an error that the login attempt failed. until the account is locked out. Once the account is locked out (by default 3 wrong attempts locks the account), the remote session is made. But unfortunately, the account is already locked by that time.
Any ideas about this? Any pointers would be helpful. I am not sure where to look at logs to get more details as well.
