So far I have only seen this tcps erro on a normal client. It semeed to me that it was because 3.70 was installed, and since the option string havs changed (i.e. TCP,NETBIOS → TCPS,TCP,NETB) I thought it was to do that, so I did an uninstall reinstall and it came good. BUT I think I lucked out, I do think that there is something more, and would appreciate also if anyone knows the answer.
