W2K8/Windows7/SMB2.0 - It takes 4sec until a new qtree can be accessed after creation




we've an application that creates qtrees and shares including security settings that runs for a long time without problems (Windows XP client,...).

Now the customer uses Windows7/W2K8R2 to run the tool. Since then we see that the tool stops because the qtree is not available after creation thru the API.


Our test showed that in an SMB2 environment (SMB2 on the filer enabled - DOT 8.1) it takes up to 4 seconds that a newly created qtree can be accessed

for applying securtiy settings.


cifs.smb2.client.enable  off   

cifs.smb2.durable_handle.enable off

cifs.smb2.durable_handle.timeout 16m

cifs.smb2.enable         on  

cifs.smb2.signing.required   off


Does anyone have seen this behavior?


Thanks in advance
