Disable opportunistic locking on Server 2012 R2 - Is downgrading to SMBv1 really the only way?

We have an application that uses an Omnis 7 datafile (a service-less, Access-like database, from what I understand).  The application vendor has told us that opportunistic locking must be turned off on the server hosting or the clients accessing the
datafile, or there is a greatly increased risk of corruption of the Omnis datafile.
We are migrating some applications from a 2003 server to a 2012 R2 server, including this datafile.  I have read about opportunistic locking on 2012 R2.  It seems opportunistic locking is hard-coded into both SMBv2 and SMBv3 and there is no way
to disable it without disabling SMBv2 or SMBv3.  Is this true?  Is there truly no other solution for this but to downgrade my server to use only SMBv1?

Hi Scott,
As you said we cannot disable Opportunistic locking in using SMB2 or SMB3.
See:
https://login.live.com/kb/296264/en-us
•The opportunistic locking registry keys are valid only for traditional SMB (SMB1). You cannot turn off opportunistic locking for SMB2.
From your description it is the limitation of the application - SMB2 comes with Windows Vista /Windows 2008, which means the vendor of the application did not recommend to use SMB2 or the application is released for earlier systems while SMB2 is not available
at that time.
You can confirm with the vendor to see if any upgrade version of that app which is suitable for newer operation systems.

  • Turning off Opportunistic Locking in Windows 2012 Server?

    I have recently switched my database hosting and am having trouble with "Hour Glass" for about 20-30 seconds when trying to save files.  I have contacted my application company (Resumate..........database,CRM built on an ACCESS type platform)
    and we are brainstorming solutions.
    One solution is to turn off opportunistic locking as Windows might actually be locking the file (We have five users using the same file connecting using Remote Desktop Services).  Our system has worked seemlessly with our other hosting
    option but this delay when trying to save files is not acceptable.
    SO, HOW DO WE TURN OFF OPPORTUNISTIC LOCKING IN WINDOWS SERVER 2012 R2?
    Thanks Phil H.   Charlotte, NC

    If there is no update version, you can try to disable SMB2/3 on server to workaround it. Please run this cmdlet:
    Set-SmbServerConfiguration -EnableSMB2Protocol $false

  • I cannot seem to find the Version 3 print drivers to make XP work from my server 2012 r2 environment. I read that the v3 should fix the XP errors I continue to get, but WHERE do i dowlnoad these? Cant find them anywhere.

    Does anyone know where to find V3 drivers rather than v4. I'm having issues with XP working in my server 2012 environment.
    Thanks in advance!

    the vendor provided version-3 compatible print driver should be used for the device. Check Windows Update and the device manufacturer for a v3 driver.
    Best,

    Second: In firewall If I want to check (read-send) mail via entourage in this server. I can not connect to the servers. I enabled all the ports that says SSL, email,mail,etc, but I can not connect to the SSL servers to check email. The only way to red-send email is disabling the firewall!
    The next one is realated to SAFARI:
    Third: If I open Safari and I try to open Hotmail.I can not access Hotmail via Safari. trying to opening that site is impossible. a link in hotmail is detected with an internal address of 10.x.x.x. (which my computer does not have). Then the only way that I have to access hotmail via Safari is disabling the firewall, then the page is opened!
    Fourth: I can not read the hotmail mails inside entourage. .. again, the only way to read and send mails from hotmail in entourage is by disabling the firewall!!!
    no one answered posts related to this in the networking forum. so I am posting it here.
    any idea????

  • HT4061 I forgot my 4 digit lock passcode & now cannot get into the 4S iphone - Is the ONLY way to fix this to restore to factory settings? I haven't synced my phone to my computer in a loooong time -

    I setup my 4 digit lock & now cannot login (thought it was what I wrote but not working; I have not synched my computer w/my Iphone in a

    Yes, that's correct.
    Locked Out, Forgot Lock or Restrictions Passcode, or Need to Restore Your Device: Several Alternative Solutions
    1. iOS- Forgotten passcode or device disabled after entering wrong passcode
    2. iPhone, iPad, iPod touch: Wrong passcode results in red disabled screen
    3. Restoring iPod touch after forgotten passcode
    4. What to Do If You've Forgotten Your iPhone's Passcode
    5. iOS- Understanding passcodes
    6. iTunes 10 for Mac- Update and restore software on iPod, iPhone, or iPad
    Forgotten Restrictions Passcode Help
    You will need to restore your device as New to remove a Restrictions passcode. Go through the normal process to restore your device, but when you see the options to restore as New or from a backup, be sure to choose New.
    Also, see iTunes- Restoring iOS software.

    You must restore it, losing anything you have failed to backup or store on your computer or cloud service.

  • Phone works great but when on a call proximity sensor kicks in turns off the screen. When I pull the phone away from my head screen is still blank. The force hangup/lock is the only way to bring the screen back on

    hi,
    phone works great but when on a call proximity sensor kicks in turns off the screen. When I pull the phone away from my head screen is still blank. The force hangup/lock is the only way to bring the screen back on.
    I purchaged it before one month onl. So i wont understand how it comes. Please help me. I am waiting for you reply.

    "Your face is so ugly, it broke your phone!" Ha ha. Get it? How I was joking there? About your iPhone not working correctly after... <sigh>
    But seriously, you said the situation only happens when you have been on a long call, so maybe the iPhone is just autolockng?

  • Verizon is using the Elipsis tablets to steal data from their customers.  The only way to stop data from registering as cellular data is to pull the SIM card.  This occurs with wifi enabled and cellular,dara disabled.  If,you take your tablet to a Verizon

    Verizon is using the Elipsis tablets to steal data from their customers.  The only way to stop data from registering as cellular data is to pull the SIM card.  This occurs with wifi enabled and cellular,dara disabled.  If,you take your tablet to a Verizonstore they will upgrade your data plan to cover the overage and credit the upgrade.  You will then have to remember to downgrade your plan or continue to pay for more data.  Verizon, how would you feel if I walked into one of your stores and started filling my pockets with merchandise?  If cought can I just give the product back and say "oops, sorry"

    Today, my FCC complaint hit the same person working on the BBB complaint.  Jimmie has been very nice and seems willing to work with this problem.  We have been able to come to an agreement.  I paid the purchase price for the phone and he returned my upgrade and unlimited data plan.  This is what would have occurred if Verizon had given me correct information to begin with.  I am happy with this result.  He also brought quite a few instances concerning the handling of my transfer and upgrade that did not follow proper procedure.  I am also confident that I would not have resolved this without complaining to BBB and or FCC.  Verizon had no interest in solving the problem nor did they show any propensity to keeping a 20 year client.  Even though this last CSR was very polite and helpful, his sole job is to respond to formal Federal and State complaints.  He is required by law to address every complaint and report the reporting agency the agreed upon results - good or bad.  Again, I suggest - If you are not getting the proper customer service, complain to someone outside of Verizon.  Jimmie had not received any complaints registered with Verizon directly and I still have not had any contact with any other management representative that I was told would call.

  • If you have forgotten your passcode lock is the only way to unlock is from the original computer?

    If you have forgotten your passcode lock is the only way to unlock the phone to connect to the original computer? Is there no way to connect to itunes? HELP!

    Restoring as a new device means you will loose everything.  You can restore from a backup, but if that backup includes the same passcode you cannot remember now, then it will just put it back in place and you will be right back where you are.  If the backup does NOT include the passcode currently on the device, you can restore from that backup.
    If restoring as new, you will loose any pictures in camera roll not already saved somewhere else (like your computer).  You will loose any contacts also not already saved somewhere else.
    Once you've restored the iPhone though, you can re-sync the contacts and other content from your backup copies on your computer.  iTunes and App store content can always be redownloaded.

  • IOS6 on iphone 4S. My phone keeps disconnecting from my wifi. I have to input the password each time. The only way i can keep wifi connected is to disable cellular data....what's with this????!!!!!

    I downloaded IOS6. The next day my iphone was not connecting to wifi. I reset network connections...put in my password and voila it worked!....But then it dosconnected again..and again...and again....my wifes iphone 4 is not having this problem and she also installed IOS6. The only way I can stay connected to wifi is if i disable my cellular data. What is going on???...Anyone?......

    Is it a BT Yahoo account? If so, there have been quite a few threads about Yahoo constantly rejecting passwords, with no clear fix.
    That said, I did see someone post that they'd resolved the problem by eliminating any capital letters from the password. After that it stopped asking for passwords and started working, apparently. One or two others tried the 'fix' and seemed to have the same success. At least they haven't come back to say it had gone wrong again.
