I recently ran into an issue where an administrator had left the company, and unfortunately he was the only one to know which server was the dirsync server. Prior to beginning this task of restarting the Dirsync service, we discovered that no one knew which server was running Dirsync. This particular admin had over 72 servers that they were responsible for, so rather than going through each server to look for the program or the sync service, I found another trick to find the server running dirsync.
All you need to do is go in to the Active Directory Users and Computers and find the MSOL account. In the description of the account it will list which server to which the application was ran.
- Open Active Directory Users and Computers.
- Search for the account “Msol”.
- Open the description. The description will tell you where AAD Connect was installed. Scroll to the right, or copy and paste the entire description in a notepad.
