Hi my webserver is running .Net 1.1 and intermittently i get the
following error when I look at one of the websites. Does anyone out
there have any idea why this happens?
And how I can try and start solving the problem. Most of the time the
website works okay. Thanks in advance!
Server Error in '/Ed/ENROL' Application.
