Here is a familiar sounding situation:
I have a user in a remote office who uses a published application on our Citrix Metaframe XP server in our office. She connects through the internet - she has the ICA web client installed. This setup has been working perfectly for the last several months.
Today she calls and indicates to me she is not able to connect, she reads me the error:
"Network or dialup problems are preventing communication with the Citrix server..." The dialog indicates 30 seconds until a reconnection attempt (counts down), and the user can push "reconnect" or "cancel".
I then remote onto another computer in the same office (using Dameware RC), and try to connect back in to our Citrix server. Sure enough, I am able to login and authenticate to the nfuse portal web site, and I can see my selection of published apps. However, I receive the same error - it pops up nearly instantaneously. While remoted in, I ping the server and pings are nominal - average between 30 and 100 ms, some up to 150-200 ms.
It doesn't make any sense why out of the blue, computers in that office can no longer connect.
I did a search on the forums here, and tried some of the suggestions when encountering latency - but still I receive the same error. I added the "TcpMaxDataRetransmissions" registry entry, and verified that the ICA settings were all set to no timeout. I set up a sniffer and the particular workstation I was on and the server are able to talk to eachother OK. No problems there. Plus, there are users connected that are connecting from more latent networks - I checked their ICA sessions in Perfmon.
Any suggestions? I think a simple red light bliking somewhere would be more informative than this error. Is there some sort of troubleshooting utility that can be used to specifically troubleshoot ICA connection problems?
Thanks,
Michael Pare
