I am trying to connect to an ArcGIS server as an admin and have entered all the connection properties for my organisation ( server URL, User Name and Pass ) correctly. However when I double click on the server connection in ArcCatalog I get the egg timer spinning for a minute or two followed by an error message stating "arcgis server slow down request rate. (status code 503)"
Using a different Admin account which was already setup with the same connection properties, I can connect fine to the server. I have looked at the connection properties for this acount and as far as I can tell they the settings are the same.
Can anyone help on why I am geting the above message and how to solve this issue ?
Many thanks in advance.
