I am unable to add a person as local admin to a computer. I receive an error, "Windows cannot process the object with the name :Domain Users" because of the following error: Not enough storage is available to complete this operation". I have administrative rights as local admin, as well as domain rights. I also can't add a computer to a domain. It states, "Not enough storage is available to complete this operation". Each issue is happening on many computers. I have checked my Active Directory account with other people who are able to add to domains, but there are not any differences. All of the computers have at least 1GB RAM, and have plenty of hard drive space. Any ideas?
