This is a 3 unit Mark5 with an HMI at each unit and a server HMI in control room. all running XP. I rebuilt the server HMI and am unable to get TCI, or the project, to start. I am testing our ability to restore an HMI. I am using an available Dell PC, as opposed to the HP brand supplied by GE. I used the images supplied from the original install, then updated the Unit directory with a recent copy of those files. I had to update drivers for the network card and installed an Arcnet card. I shutdown the Server HMI and am attempting to replace it with this new box. I set the IP and Arcnet addresses to what the Server was. I am able to Remote Desktop to the other HMIs and run the Cimplicity projects that way but I cannot get the project to run on this machine. All username and passwords are the same. I noticed the TCI does not start. It gives a message: "Error 1331:logon failure:Account currently disabled". I noticed the Arcnet card lights are not on or flashing. I have tried one [light] I know is good so this may be a key issue, but I am not sure how to get it going. Drivers appeared to load for it. Any ideas would be appreciated.
