workstation could not connect to the system
One workstation (16 workstations in totoal) seems lost the connection to the system, it shows "Could not connect to the system! Reason: Wating for a connection to the ABB Automation system...". It is still available in RNRP, no problem of remoting in or out.
We have tried:
- Reboot both connectivity servers;
- Reboot both domain controllers;
- Remove workstation from domain controller, reboot workstation, rejoin domain, reboot workstation and domain controllers.
- Reboot both aspect servers;

RNRP shows only that the basic network is connected and valid IP adresses are set. So at least that is working.
- Check the network settings on your cards, especially the "Register in DNS" and "WINS" settings in the primary and secondary network cards. Also, make sure you have not made a simple error in Domain Controller addresses or subnet masks.
- From a command prompt on several machines, including the Aspect Servers, run an "nslookup" on your workstation name to ensure that the name is being resolved to an IP address properly everywhere in the system.
- Check that you removed the Workstation from the system properly and cleaned up the 800xA cache files and registry settings. See this post -> http://www402.abbext.com/Adding-Clien...
- Run the config wizard and re-apply the System Software User Settings to use the 800xA service account on the domain.
- Try to add the workstation again.
Don't reboot the servers for client connectivity problems.
1. Try to ping the domain controller and aspect server.
2. open the license status viewer and look for connectivity errors if any.
3. check the system service connection status.
If still bad try to remove the client from configuration wizard, restart the machine and connect the client back.
1. Check the C:\Windows\System32\drivers\etc\hosts file (eg compare contents with other working client).
In 5.1 hosts file replaces need for DNS to resolve IP and is maintained by RNRP. If C: runs full; hosts file may be trashed by RNRP resulting in a file size of 0 bytes. Free up some disk space and restart RNRP, or use "refresh hosts file" feature from RNRP wizard. Then verify contents once more.
2. Examine [Workplace Structure]Web System Workplace:System Event List during failed workplace launches. Bad node name and/or user will result in distinct events.
3. Try disabling Windows Firewall in client. If that helps; re-run firewall wizard from 800xA media (DVD1?).
4. Contact your regional ABB support center.
