I have created and published a form on our company server. Some people can open this form with ease while others get the error "This form cannot be opened because it requires the domain level and it currently has restricted permission." It says to open the form in the location it was published to, but the employees are opening the form from that exact location. Is there a way to fix this issue?

easiest way is to ask the employees to add the site to their local intranet security group. in internet explorer under the tools tab there's a security option. click on local intranet and select advanced and have them add the site. then they won't get this error.
