Symptoms
Consider the following scenario:
-
A file is hosted on a server that is running Windows 7 or Windows Server 2008 R2.
-
You use an application on a client computer that is running one of the following operating systems to open the file on the server:
-
Windows Vista
-
Windows Server 2008
-
Windows 7
-
Windows Server 2008 R2
-
-
The application opens the file by requesting read/write permission and DENY_WRITE share mode.
-
You close the file.
-
You try to use the same application on a client computer that is running Windows XP or Windows Server 2003 to open the same file.
In this scenario, you receive the following error message:
ERROR_SHARING_VIOLATION (32).The process cannot access the file because it is being used by another process.
Notes
-
You receive this error message twenty to thirty seconds after you close the file on the first client computer.
-
This issue does not occur if all client computers in the network environment are running Windows XP or Windows Server 2003.
-
This issue does not occur if all client computers in the network environment are running one of the following operating systems:
-
Windows Vista
-
Windows Server 2008
-
Windows 7
-
Windows Server 2008 R2
-
Cause
This issue occurs because an SMB2 client does not send an SMB2 CLOSE request to the server within twenty to thirty seconds when an application on the SMB2 client closes a file. If the same application on an SMB1 client opens the same file during this period, the server cannot start the OpLock break behavior and returns an "NT STATUS_SHARING_VIOLATION" error to the SMB1 client. This behavior prevents the SMB1 client from opening the file until the SMB2 client sends an SMB2 CLOSE request.Notes
-
The following operating systems use the SMB1 protocol:
-
Windows XP
-
Windows Server 2003
-
-
The following operating systems use the SMB2 protocol:
-
Windows Vista
-
Windows Server 2008
-
Windows 7
-
Windows Server 2008 R2
-
