ANVA (application) in Citrix give error 3000 with the default setting, because of the refresh from the logonscript (the connection with the ANVA server will be disconnected).

Solution:
This solution is provided by ScriptLogic support chat.

ScriptLogic: there is a registry setting you can deploy through application launcher, keep in mind if you adjust this it will adjust all refresh cycles.

VP: can you tell me which registry setting?
ScriptLogic: I am getting the reg setting from an engineer give me a few seconds.
VP: OK
ScriptLogic: For whatever reason we don't publish this in the knowledge base
ScriptLogic: Hive:    HKEY_LOCAL_MACHINE
ScriptLogic: Key:     Software\Scriptlogic
ScriptLogic: Value:   EnforceTimer
ScriptLogic: Type:    REG_DWORD
ScriptLogic: Data:    60
ScriptLogic: Set the data to be any value desired (in minutes). If this value does not exist in the registry, the refresh will occur, by default, every sixty minutes
