Here is my issue and I hope that anyone can help. We have a local domain running through a windows 2012 server. We have migrated our quick books to an external company. They are also running 2012. They issued some of our users that still need access to quick books a login and sent them a RDP file to connect. The issue that we are having is that some can connect and other it keeps telling us that, "The credentials that were used to connect to company name did not work please enter new credentials." I know that the credentials are correct. Here is a list of what is working and not working (NOTE: all IP's were verified from an external website): User A (desktop) is Same IP (windows 7 pro not working) User A (laptop) is Same IP (windows 8.1 Pro not working) User B (desktop) is Same IP (windows 7 pro not working) User C (desktop) is Same IP (windows 7 pro not working) User D (laptop) is Different IP then the rest (windows 8 Home not working) User E (desktop) is Same IP (windows 7 pro WORKING) User F (server) is Same IP (windows 2012 R2 Standard WORKING) User G (laptop) is Different IP (windows 8.1 pro WORKING) User H (surface) is different IP (windows 10 WORKING) I have checked the port settings on each one individually to no avail, all of them do have administrative user credentials for that unit. All are up to date on updates and I have checked the firewall settings on each also. Thank you for any help ahead of time that you may be able to provide.
