Article ID: 810907 - View products that this article applies to.

SYMPTOMS

Client computers that are running Windows XP Service Pack 1 (SP1) and that are configured to require Server Message Block (SMB) signing may drop SMB signing and may have problems communicating over your network. For example, you may experience any of the following symptoms:

When you open a Microsoft Office file, it is opened as read-only. You must save the file locally to make changes.
You cannot copy files over the network, and network paths are not accepted by any network provider. For example, you may receive the following error message when you try to connect to an SMB share:
The file or the network path no longer exists.
You receive the following error message when you try to open a file on a network share:
Cannot open the file on network share. Make sure a disk is in the drive you specified.
