Tse Connection Time Out ?

[mumuuu]

HI all

i've a problem with a tse client which try to connect on a tse server ( i don't have the hand on this server) and when he try to connect he has this message : " connexion time out try to connect again"

i can ping the server all computer exept this one can connect without pb....

so maybe it's a problem with TSE licence ???? if u think i'm in right ???? or if u have idea on the PB ???

thx by advance ......
