this is a user permission problem. Edit on your cell server the file: /etc/opt/omni/users/UserList Add the following line for each host that will access xomni GUI (including the cell server): "root" "root" "*" "admin" After doing this you should have all the choices when running xomni.
Your symptom may co-incide with a change in NAME RESOLUTION.
As suggested above - the key is the privilege listed for each Omniback user - but you may have the user set up as being FROM a certain PC or Workstation - that user could then NOT access Omniback from other workstations.
If name resolution has changed you may find that account information that worked in the past no longer works.
Try replacing the servername with an asterisk in the cell_info file or UX GUI - or the entry if you are using the NT graphical interface.
Look at the cell_info file
The format looks like this...
"comment" "username" "group-domain" server "admin"
