All, I believe I have found a BIG clue to my "I/O Error" problems" It seems to only happen on devices that use "published applications" and not on the ones (my little test) that just connect to the server. So now that I think it's my published apps that are causing the problem, what should I do next? What settings should I check? PS. Both cases we are using TCP+HTTP browser without ICA! I plug in the IP of the one CitrixXP box we have. Once the DNS is going, I will change to using ICA. (DON'T ASK ABOUT THE DNS :-) ) Yes, I'm a newbie with Citrix... but I LOVE IT! ^^^ got Linux ^^^ Mark Guzzo Citrix Administrator "Don't Fear The Penguin." ********************************************** This weeks sponsor 99Point9.com 99Point9 helps solve your unresolved technical server-based questions, issues and incidents. http://www.99point9.com *********************************************** For Archives, to Unsubscribe, Subscribe or set Digest or Vacation mode use the below link. http://thethin.net/citrixlist.cfm
