Technical Solution


Unable to connect a remote SMSMSE Administration console.

1. Start the remote SMSMSE Administration Console.
2. The SMSMSE Administration Console attempts to connect to the remote server.
3. The SMSMSE Administration Console "times out" and displays a dialog box to enter authentication credentials.
4. Enter the credentials.
5. The SMSMSE Administration Console attempts to authenticate but fails.

At this point the remote console is unable to connect to the SMSMSE services on the remote server.




  • The Windows Application Event log on the server with the SMSMSE Administration console contains the following error event:

  • Version of SMSMSE on remote server is 6.5.5 or higher.


The binaries for SMSMSE are digitally signed.  Windows attempts to validate that the certificate used to sign the binaries has not been revoked.  If the remote server does not have Internet access or a firewall or proxy is blocking access to the sites used for certificate revocation Windows waits until a timeout period is encountered.  The SMSMSE Administration console times out during this process.



Turn off Certificate Revocation Checking for IIS using the following steps:

Note: If the server experiencing the problem is running Windows Server 2003, a patch must be applied for this configuration change to take effect, see "FIX: A .NET Framework 2.0 managed application that has an Authenticode signature takes longer than usual to start" for details and to download the patch.

1. Use a plain-text editor such as Windows Notepad to create a configuration file that contains the following lines:

        <generatePublisherEvidence enabled="false"/>

2. Save the file as w3wp.exe.config in the same folder as w3wp.exe. For example:


        This turns off checks by all web applications on the server.

3. Restart IIS by going to Start, Run, and type in CMD. In the command prompt type "iisreset" and wait for the restart to complete.

The remote console should now connect and authenticate without excessive delay.
