The only way you can change the OpLocks setting as far as I know is to use SMB1 and that means disabling SMB 2/3. Despite what I've seen here from some folks I greatly respect, indicating that MS has finally gotten this right, I still recommend to my clients that SMB v1 be enabled with OpLocks disabled and SMB 2/3 disabled as that has produced the most stable environment. Having said that, is it possible that the Citrix 2008 server is not up to date with its patches?

The initial change to the save can be several minutes as the user is talking to a customer. There are between 100 and 150 user, with these tables open most of the day. The new environment: SAN hosts VMs Dedicated VM for data files, Server 2012. Citrix running on Server 2008 R2. Old environment: Physical boxes Dedicated Server 2003 (SMB 2 is disabled) Citrix running on 2003 servers Migration began after testing the VM data server with the 2003 servers. Index corruption was reported within hours of some users being on the 2008 R2 servers. Write Cache appears to be off in the Server 2012. Is the Opportunistic Locking the probable culprit of the corruption noted here?
