Force SMB v1 on Windows 2008 Server

[Guest Christophe CHESNEAU]

Hello,

 

Is it possible to force SMB v1 in 2008 Server ?

I have 1 W2K8 Data server and 2 W2K8 TS with an old Windev application

which use indexed file for it database and I have a lot of corruption in

these file due to Opportunistic Lock.

My problem is that in 2008 Server, the opportunistic locking couldn't be

disable because of the version 2 of SMB.

 

Could we limitate the Lanmanserver service to emulate uniquely SMB V1 ?

 

Thanks in advance. Regards

Hello Christophe,

 

SMB2 is only used when all OS have the same verison running, if one doesn;t

support SMB2 it will automatically use SMB1.

 

Have a look on this one:

Hello Meinolf,

 

Thanks a lot for your response. I try it immediatly, I hope mrxsmb1 and

mrxsmb services under Windows 2008 understand the OplocksDisabled value (I

put it in both services key).

In my case, the 3 servers are in Windows 2008 (1 data and 2 TS) and its

automaticaly use SMB2 by default.

 

Thanks another time. I will give you a feedback if it works. ;-)

Best regards.

 

Christophe
