Is there any AAC admin happy with the way, EPA scans behave? Once you create just one EPA scan in the AMC (Access Management Console), the EPA scan gets started automatically on every LogonPoint, regardless whether this is wanted/needed or not.

This behavior is for example very annoying at OWA (Outlook Web Access) LogonPoints, that are created only to allow restricted access to the personal mail from anywhere. To operate “client less” from anyplace, anywhere, no EPA scans may be required. On a standard LogonPoint the EPA scan appears anyway with his download and installation directions. If you click on the “Skip Scan” button, you can proceed without scanning your PC, but the download of the EPA scan client still takes place in the background, steeling you valuable bandwidth. In addition, less computer versed users in an internet cafe with restricted PCs might end up trying to install the EPA scan client over and over without a chance to succeed…

Recently I stumbled upon an option that is able to stop this “misbehavior”. Well hidden and badly documented, the chances are good, that only few people discovered this option so far. The solution can be found in the “web.config” file in the root of the respective LogonPoint directory.

On a standard AAC server this is presumably:

C:\Inetpub\wwwroot\CitrixLogonPoint\#LogonPointName#

There is an other version of this file in the “C:\Inetpub\wwwroot\CitrixLogonPoint\” directory which should stay untouched !

This file can be opened and edited with any editor like the Windows NotePad. In the last third of the file you can find a section <appSettings>, which gives you some interesting possibilities. Among other things you can disable EPA scans here. All it needs is to add the following line below the <appSettings> section:

<add key=”EndpointAnalysisDisabled” value=“true” />

The section should look like this afterwards:

<appSettings>
<add key="DebugConsoleTrace" value="False" />
<add key="AdvancedGatewayClientDownloadUrl" value="http://www.citrix.com" />
<add key="AdvancedGatewayClientActivationDelay" value="10" />
<add key="MaxConnectionsToAuthenticationService" value="20" />
<add key="LogonPointId" value="00000000-0000-0000-0000-000000000000" />
<add key="DeployedBy" value="LACONFIG" />
<add key="ExtendedSecurIdFunctionalityEnabled" value="true" />
<add key="SecondaryAuthenticationIsOptional" value="false" />
<add key="EndpointAnalysisDisabled" value="True" />
<!- -

After saving the changes, a user calling this manipulated LogonPoint will now be forwarded immediately to the login prompt without seeing any EPA “nag screen” 🙂
