External Connections at NAV2009 R2 classic client start

Anyone know why when we start up a Nav2009 R2 Classic client it attempts to connect to:

Not sure if it is related to third part add ons we have Lanham, Crargelogix, Altus, ???

Any ideas? We have some production machines where we block external access and it takes forever for Nav to open up dur to trying to make these connections.
