One Domain with primary and additional doman controllers (Windows 2008 r2 ee)in first site. One more Additional controller in second site. Functional set as windows 2003 and there are 100 clients machines which are running windows 7 Proffessional. Some times while logging into domain in clients machines with domain id. It gives the error as " trust relationship between the workstation and primary domain controller failed Windows 7"
As a one time soultion we had re-joined it domain. Same cant be done for all the clients whenever their facing that issue.
