256986 Description of the Microsoft Windows Registry



SYMPTOMS
When you try to use the Computer Associates eTrust Antivirus Remote Install utility to install the eTrust Antivirus 7.0 client on a computer that is running Microsoft Windows XP Service Pack 2 (SP2), the installation does not succeed. When you click Install to Targets, you receive the following error message:

Installation failed: Access is denied. (5)



CAUSE
This behavior occurs because of changes to the Remote Procedure Call service in Windows XP SP2. By default, the RestrictRemoteClients registry entry is turned on in Windows XP SP2. This registry entry restricts access to all remote procedure call interfaces.



WORKAROUND
Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To work around this behavior, install the eTrust Antivirus client locally. If you cannot install the eTrust Antivirus client locally, you can modify the registry to turn off the RestrictRemoteClients registry entry. To do this, follow these steps.

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.  Click Start, click Run, type regedit, and then click OK. Locate and then click the following registry subkey:

If this subkey does not exist, follow these steps:  Locate and then click the following registry subkey:

 On the Edit menu, point to New, and then click Key. Type RPC as the subkey name, and then press ENTER. Right-click RPC, point to New, and then click DWORD Value.</li> Type RestrictRemoteClients as the entry name, and then press ENTER.</li></ol> </li> Right-click the RestrictRemoteClients entry, and then click Modify.</li> In the Value Data box, type 0 (zero), and then click OK.</li> Quit Registry Editor.</li> Restart your computer.</li></ol>

If you modify the registry, we recommend that you turn the RestrictRemoteClients registry entry back on after you install the eTrust Antivirus 7.0 client. To turn the RestrictRemoteClients registry entry back on, set the value to 1 or to 2, and then restart your computer. By default, the value of the RestrictRemoteClients registry entry is 1 in Windows XP SP2.
