[Solution]: SharePoint Peoplepicker not displaying domain users
I have configured peoplepicker for about more than 10 domains. All works fine except for a domain. There was no error and only message is that the "No results found" in the People picker search results. How People picker works? People picker sends a dns query to the domain controller to retrieve the AD details. How did i resolve this issue? I ran network monitor in all the DCs. Search for a user in people picker Go to the nework monitor logs and search for the name you searched in the people picker. That will give some idea, what went wrong. Additionally, search for the destination DC. Repeat this if you are connecting to AD domain through multiple DCs. In my case, there was no response from the destination DC, which was caused by firewall port. After the port was opened in destination DC to the AD domain, the issue was resolved. Hope this helped someone out there. Happy trouleshooting!
