DCOM Errors where Windows 7 Enterprise is still trying to connect to non-existent DC's. We removed our Windows 2003 Domain Controllers and are strictly 2008 Domain Controllers. We have some Windows 7 test machines and they are trying to connect to the old domain controllers. The old DC's are not in DNS, AD, hosts, lmhosts, etc. but my clients are still trying to talk to them. Any suggestions?
