Whenever I try to add a server under server administration on Starport, or sometimes even login, I get this error

Server Error in '/' Application.
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".

<!-- Web.Config Configuration File -->

<configuration>
<system.web>
<customErrors mode="Off"/>
</system.web>
</configuration>


Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

<!-- Web.Config Configuration File -->

<configuration>
<system.web>
<customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
</system.web>
</configuration>

Is this still happening after the recent starport reboot/repair? I just tried to add a new server from home and was successful. Perhaps there's something you're filling in a field which it isn't happy with? Try just leaving everything as default, and only filling in the IP address and server name (keep that really simple too). Perhaps there's a special character or something that it hates...

It's working now, although this error does pop up at seemingly random times, and has done for at least 2 year for me.

I'm guessing when this is malfunctioning, everything else is too, and everything needs a restart.
