Hi,
Im kind of new to Windows Active directory environment. Recently in my company there is project has been initiated to replace exiting active directory windows 2008 r2 to window 2012 r2.
Initially we have two DC server (srv1 and srv2) installed with windows 2008 r2 server and srv1 is the PDC. Now as part of the project we have added two new DC (srv3 and srv4) installed with windows 2012 r2 in our AD environment. Now we have have 4 DC 2xwindows 2008 and 2x windows 2012. After adding the new DC (windows 2012) we have started encountering an issue with our CIFS file server files. The issue if the client PC log-on server become srv1 or srv2 then CIFS files are fine accessible as per the ACL but if the client PC log-on server become srv3 or srv4 (which is NEW DC windows 2012) then CIFS files on the file server become read-only mood and cant able to do any write operation even though the ACL is permitted.
I have gone through many sites but couldnt find any such solution regarding this. As project dead-line pretty near and Im kind of new to windows AD environment so it would be appreciable somebody could help on this.
