I am unable to install any application on a Windows 2003 Server. The 2k3 server is not a domain controller. The network is being run on a Windows 2000 Server. The 2000 server handles Active Directory and DNS. Whenever I try to install something on the 2k3 server, I get an error message that the install was interrupted and could not complete. The installation rolls back any changes made. In particular, I've tried a timeclock program and Adobe Acrobat. I've logged in as a local administrator and as the domain administrator and as a new user administrator. I've disabled my firewall and my Norton Corporate Edition antivirus. Anyone have any ideas? I'm completely lost.
