It seems like everyday I go to publish a service or connect to my SDE I get messages that I can't connect. It is particularly annoying when trying to publish a service to ArcServer. The connections are made, but for some reason they are timing out or becoming temporarily disconnected for whatever reason (Red X over the connection icons).
The fix is simple: As soon as I open Catalog and then double click on the connection, it re establishes connection and then I can do what I need in ArcMap. However, ideally I would like to stop this behavior.
Any ideas why this is happening? Can't find much in the help and it has been mentioned by several users in my organization.
