OK, we have failure.
The strange thing in all of this is that if a server is presently on the Calavera map, he can see it & join. If it is on any other map, it doesn't show up on his server list.
He has enabled DMZ in his router, opened every port listed for GRAW 2, isn't running any firewalls or AV's, has uninstalled/cleaned the registry/re-installed (using the 1.03 patch one time, uninstalled/reinstalled using the smaller incremental patches), and still can't see all of the servers we see.
His comp/game was working perfectly before the 1.03 patch. He is on a network, and his son's comp can see and join all of the other servers we see.
He's run the following progs: AV, adaware/spybot, registry mechanic, hijackthis!, and lspfix. All to no avail.
Again, the weird part is the Calavera map situation in all of this.
Any ideas? Anyone?
