Another one of those mysteries. metaframeXPa running on win2k servers on nt4 network. Remote branches connected via 56k frame circuits.(I know, we're working on it). Micom Marathon routers (don't ask). 4-user branch running win 9x, ica 6.3. One user tried to log on, message that citrix server not available. Another user bumped off, tried to reconnect, same message. Another user logged off, tried to get back on, same message. All members of one domain. Static ip addresses. Can ping citrix servers both by name and ip address. Can see servers in network neighborhood. Can ping user from server. Finally bounced Micom router. ok now. Has happened at 3 different branches now.
