We have five Citrix servers. In general we have all our applications on all of the servers, except one. There are two programs that are only available on one Citrix server. Using Program Neighborhood, logging onto one of the other servers, then trying to open that application works as expected by opening a new session on that server. When accessing these two applications via Web Access from a computer that IS part of the domain works. I can Web Access these applications from my work laptop both here on our network and anywhere else. From my home computer (NOT part of our domain) I cannot get these two applications to open. It reports, "You do not have access to logon to this session." I can get to every other application that I've tried other than those couple. I have tried the same thing on at least three different domain and non-domain computers. I have pass-through authentication enabled so the domain computers don't have to enter the initial credentials whereas a non-domain computer is required to enter "domain\usernmae" before the Web Access console even comes up. That's long but hopeufully somebody can help. Let me know if I need to clarify anything.
