Files on network shares open slowly, open as read-only, or you receive an error message
Important This article contains information that shows you how to help lower security settings or how to turn off security features on a computer. You can make these changes to work around a specific problem. Before you make these changes, we recommend that you evaluate the risks that are associated with implementing this workaround in your particular environment. If you implement this workaround, take any appropriate additional steps to help protect your system.
You may experience any one of the following symptoms:
- When you copy a file over a network in Microsoft Windows
XP, if the source file is located on a Microsoft Windows 2000-based network
share, you may receive either of the following error messages:
File or network path no longer exists.
No network provider accepted the given network
- When you try to open a file from a network share, the file
may take longer than expected to open.
- You may receive various error messages or experience other
issues when you use a program that opens and closes files or that creates
temporary files on the server if the Windows 2000-based server has Server
Message Block (SMB) signing turned on.
- A file that you opened over the network is opened as
read-only, or a sharing violation occurs and you must save the file locally to
This issue may occur even if your permissions are set
to Full Control for both the share and the volume that uses the NTFS file
system, and no other user has the file open. In this case, you may receive one
of the following error messages:
File in use:
Filename is locked for editing by
username. Click 'Notify' to open a read-only copy of
the document and receive notification when the document is no longer in
This command is not available because the
document is locked for editing.
Filename is locked for editing by another user. To
open a read-only copy of his document, click...
File is locked for editing, do you want to open a read-only
version of the file.
Filename on network
share. Make sure a disk is in the drive you
Access is denied. The file may be in
use by another application.
- When you open files, programs such as Microsoft Excel or
Microsoft PowerPoint may open two files successfully but display a "Read-Only"
error message when you open a third file.
- When you open or when you close files, network programs
that rely on heavy network file input/output (I/O) may seem to stop responding,
or delays may occur.
- You may experience issues when Windows XP applies group
policies or runs logon scripts.
- You can save a Microsoft Office file by using the same file
name only after you have the file open for at least 30 minutes.
- You may also receive other error messages, depending on the
program that you are using. For example, you may receive error messages that
indicate that a file is already in use or that a file can be opened only as
This issue may occur if any one of the following conditions
- There is an issue with negotiating SMB signing from a
client that is running Microsoft Windows XP Service Pack 1 (SP1) to a Windows
2000-based server that requires SMB signing.
- Another process has the file open and locked. For example,
this issue may be caused by either of the following items:
- The network folder is open in Microsoft Windows
Explorer and you are using Details view to display additional details (such as
the author or title) for files in the folder. Windows Explorer reads the
contents of the files in the folder to obtain the additional details. If a
program tries to open a file exclusively and Windows Explorer has the network
file open to extract this additional file information, a sharing violation
- Another program or process, such as an antivirus
program (either on the client computer or on the server), may have the file
This workaround may make your computer or your network more vulnerable to attack by malicious users or by malicious software such as viruses. We do not recommend this workaround but are providing this information so that you can implement this workaround at your own discretion. Use this workaround at your own risk.Note
An antivirus program is designed to help protect your computer from viruses. You must not download or open files from sources that you do not trust, visit Web sites that you do not trust, or open e-mail attachments when your antivirus program is disabled.

To resolve this issue, follow these steps:
- Download and install the MS02-070 security update that is
described in Microsoft Knowledge Base article 329170 on all Windows 2000-based
and Windows XP-based file servers and client computers.

Service Pack 1 (SP1), and then obtain and install the hotfixes that are
described in Microsoft Knowledge Base articles 328170 and 812937.

- If you have not resolved the issue, disable network drive
scanning in your antivirus program. To turn off your antivirus program, see the
antivirus program documentation or online help for steps and information about
how to do this.
If the issue is still not resolved, temporarily turn
off your antivirus program. Sometimes, you may have to remove antivirus
software on both the client and the server to troubleshoot this issue. If
removing or disabling your antivirus program does not resolve the issue, contact the
manufacturer of your antivirus program for additional information about this
issue and the steps that you must take to resolve the issue. For example, visit
the following third-party Web sites for information about how to resolve this
issue with specific antivirus products: Microsoft

Network Monitor traces may show "DOS Error, (5)
ACCESS_DENIED" or "DOS Error, (32) SHARING_VIOLATION" error messages after 35
seconds (between "SMB: C NT create & X" commands for the same file name).
The time that the server waits for an Oplock Break response is controlled by
