Receiving message "an active directory domain controller could not be contacted..." when trying to join to a domain after a windows anytime upgrade to windows 7 professional. I made sure the domain name "CLC.DOMAIN' was typed correctly. From the server R2 2008 domain controller I can browse the folders for this workstation, but can't join.

Hi, The issue may related with DNS cache on Windows 7. Please register DNS via command: ipconfig /flushdns ipconfig /registerdns If the issue persists, try to type IP address instead of domain name when join the domain. Furthermore, you can manually set the DNS server on Windows 7 local area connection---properties---IPv4 Hope that helps.
