We had a newly setup server exhibit a very slow logon due to hanging at 'Other User Welcome' screen (for a minute or two). I could not find anything related in the event logs. I couldn't find anything relevant on the system to explain this hang.
I googled this issue and finally found something that worked. The problem had to due with the server and Azure Active Directory.
I was able to fix the slow logon by running the elevated command: dsregcmd.exe /leave
Before disjoining it, if I ran the command dsregcmd.exe /status everything appeared normal to me and it appeared to be AAD joined. I am not sure why leaving AAD resolves this slow logon issue but I wanted to document it in case this helps anyone else.
