I have network of about 300 computers and have a Windows Server 2012 R2 file server with Windows 8.1 clients. It has been running fine for last over a year but for last couple of weeks, I am having a terrible time resolving the issues with Folder Redirection, profiles and shared folder access. Too many users are complaining about not being able to access their redirected home folders, profiles not loading and drives not mapping.
The only change I remember making is patching the servers and the clients but I have rolled back all patches as I thought this will fix the problem but it hasn't. My users are getting very frustrated now as they are not able to do their work. I have tried everything I could do.
The biggest problem is the the sporadic nature of the problem which means it is affecting only some users and computers at any given time and others do not have any problem but it may affect them next time day. Also, the issue goes away sometimes after restarting the computer or after running gpupdate on the computer but other times this does not fix it.
These are the error messages I am getting on the client computers-
Event 1521 (Error)
Source: Microsoft-Windows-User Profiles ServiceWindows cannot locate the server copy of your roaming profile and is attempting to log you on with your local profile. Changes to the profile will not be copied to the server when you logoff. Possible causes of this error include network problems or insufficient security rights. If this problem persists, contact your network administrator.
DETAIL - Windows cannot find the network path. Verify that the network path is correct and the destination computer is not busy or turned off. If Windows still cannot find the network path, contact your network administrator.

Here are the error messages from Group policy results-
Event ID 1085
Windows failed to apply the Folder Redirection settings. Folder Redirection settings might have its own log file. Please click on the "More information" link.
Event ID 1112
The Group Policy Client Side Extension Folder Redirection was unable to apply one or more settings because the changes must be processed before system startup or user logon. The system will wait for Group Policy processing to finish completely before the next startup or logon for this user, and this may result in slow startup and boot performance.
I would like to resolve it asap and will appreciate if someone can assist me in doing so.
Thanks in advance.
