[ISS Support Case] Getting Impossible error when trying to connect to Historian server

Last updated: March 7th, 2025

Description

All of my users are having problems connecting to the historian server. The server name, user, password are not being saved by the historian client. This is applies both with the Excel plugin or the Trend tool. The process of connecting is long and tedious. There are error messages at every step. Example of the error pop-op and the text from the dialog error box. These problems began when our company wide domain name was changed and all users had to update their laptops and began using new Windows usernames. Surprisingly I have not had any of these issues after my updates.
