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.
When you attempt to copy and paste or perform a drag-and-drop operation for files in either Windows Explorer or Microsoft Internet Explorer, you may receive the following error message:
Your current security settings prohibit copying or moving files from this zone.
This behavior can occur if security zone settings for the My Computer security zone are in place. However, you can still copy files from a command prompt.
Warning 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.

Under Security Zones, click to select the Import the current security zones settings check box, and then click the Modify Settings button.
Under the Select a Web content zone to specify its security settings section, click My Computer, and then click Custom Level in the Security level for this zone section.
In the Security Settings section, scroll down to the Downloads section and change the option from Disabled to Enabled under File download.
Under the Miscellaneous section, under the Drag-and-drop or copy and paste files option, if the option is set to Disabled, change the option to Enabled.
This behavior is by design.

When a computer is a member of a Microsoft Windows 2000-based domain, and you apply the policy setting at any level above Local Policy, such as, organizational unit or domain as part of Group Policy, the organizational unit or Domain policy can override the Local Security policy and revert the settings back to the more restrictive mode. To prevent this behavior, authorized personnel can make the changes to the domain or organizational unit's Security Group policy.
