Error: An error has occurred on a page you were trying to view. The Signup Server is not running.

Symptom:

When logged on to the Nerve Center against the Main Branch every function and page works correctly. However when logged on against the Remote Branch some pages return the error "An error has occurred on a page you were trying to view. The Signup Server is not running."

Workaround:

The two branches are joined across a LAN, separated by routers and firewalls. The Nerve Center is trying to ping the Remote Branch Signup Server. The routers and firewalls are blocking the ping requests.

A temporary solution is to comment out code in the page which pings the SignUp Server - InitPage.asp:

// Initial test to catch errors if SignUp server is not available
if (!BranchObj.IsServerRunning())
{
throw new Error("The SignUp Server is not running.");
}

becomes:
// Initial test to catch errors if SignUp server is not available
//if (!BranchObj.IsServerRunning())
//{
// throw new Error("The SignUp Server is not running.");
//}
