CTC frequently loses connections to one or more NEs, and a CTC alert message that states, "Lost Connection" appears. Usually, the connection recovers within one to two minutes. However, any unsaved tasks before the disconnection are lost.
This problem occurs due to an issue with the Windows XP ICF configuration. If ICF is enabled on a LAN connection with other computers, ICF blocks file and printer sharing. This is the root cause of the issue, and this message appears when ICF is enabled. You must disable ICF in order to solve the problem.
