How do I fix a username problem across multiple devices on the same domain?
I changed the subnet mask of my DHCP server from /16 to /24. When systems weren't responding, I changed it back to /16. Though a correlation is highly unlikely, this resulted in my users being unable to simultaneously login to multiple devices as they were able to in the past? I am getting the following error messages:
1. "The system could not flog you on due to the following error: The specific domain eithre does not exist or could not be contacted"
2. "Logon Unsuccessful:
The user name you typed is the same as the user name you logged in with. That user name has already been tried. A domain controller cannot be found to verify that user name."
