Server is Windows 2008 R2

I am the domain administrator

In my Printer Manager (deployed printers), I have three printers I'm trying to remove (retired printers now). When I highlight one and choose Deploy with Group Policy (and the box opens up), I see the printer listed and have the option to remove it. However, when I try to remove it, I get an error:

"Removing Printer connection "\applied\Back Copier on Applied 2" from per machine GPO "Default Domain Policy" failed. The specified domain either does not exist or could not be contacted.

Applied is the name of my server. My domain does exist and it's the only domain I have.

See here: Print Manager Screenshot

Some random person told me to run gpresult /r on the printer. That can't be done. I can run it on the workstations and server. If I run that on the server I only have one group policy on my server - the default domain controller policy. My "default domain" policy is what runs on all the workstations, which includes the printers. However, they can't be removed from the Default Domain policy because the printers were deployed via the printer manager and attached to the Default Domain policy. Should I temporarily disable this policy to remove the printers? I'd rather not remove that policy (unless I can replicate it, disable that one, remove the printer, then enable it and then disable my Default Domain Policy).

Any suggestions here? Thanks in advance for your reply.
