Upgraded client from 2007A to 8.82, then to 9.0PL14.
All done successfuly, except some client fail to login DTW, return an error (Connection to <server ip address> has failed, Error code : - 129 Connection with license server failed).
Some client can connect, some failed, means setting at server side should be correct, firewall should be ok, antivirus also should be ok.
Try to check on client pc which is fail, the conf file inside DIAPI folder point to correct server ip address, consider ok. reinstall DIAPI also not help.
Disable firewall and antivirus on client pc done, also not help.
Situation is, can show the company list, but failed when click OK button to login DTW.
Thanks and regards, greately appreciate for any idea that help to solve this problem.
