Unable to connect to Vision: The remote server returned an error: (500) Internal Server Error.

When attempting to connect to Vision, receiving the following error: 

Class:
Deltek.Framework.Controls.Client.ClientGlobals

Function:
MakeWebServiceCall
FrameworkException:
The remote server returned an error: (500) Internal Server Error.

Call Stack:
Deltek.Framework.Controls.Client.ClientGlobals.MakeWebServiceCall(className As String, methodName As String, args As Object[], passCulture As Boolean) As ReturnObject
System.Net.HttpWebRequest.GetResponse() As WebResponse

Cause:  

This error can be caused by lack of free space on the default (C:\) drive on the server.

Resolution:  

Remove unnecessary files from the drive, to free up at least 1 Gb of space on the drive.

Note:  If the error occurs for just one user, the problem will more likely be on that user's workstation instead.
