ArcGIS Server Manager may be unable to correctly process the Windows user account password. This is a known bug with ArcGIS Server Manager and will be addressed in a future patch release. Please change the password for the Windows user account being used when logging in to ArcGIS Server Manager. See the Related Information section below for more info on how to do this.
After changing the password, please log out of Windows and then log back in to ensure the changes have taken effect.
Make sure to log off the machine and log back on to ensure the changes have taken effect.
