I recently had to move a HP 8600 Pro from my office to another. I went into the Web service on the printer from a browser on the local users PC and was unable to change any of the settings. IE: Hostname, Fax number, etc. I finally had to do it from the front panel of the printer. However when I came back to my office, I WAS able to change settings for that printer from my PC.
I think I may have locked down the Web service so it was only editable from my PC's ip address or IP range. This makes sense but I cannot remember how to turn this feature off.
It looks like 802.x security. Does anyone know how to turn this off? Do I need to do it from the printers front panel or can I do it from my PC? Could not find in the users manual.
