Hi, I am placing a question which is not related to Exchange. Appreciated if anyone can answer to this. We have server 2003 domain controller, it was working perfectly fine, but suddenly we started having two problems. First: when I click on a OU and in group policy when I click on NEW it says "You don not have permission to perform this operation" and in details it says "Access is denied" and in event viewer event id 1030 Second: when I join a client machine to domain, suddenly the error msg appears " the following error occurred attempting to join the domain abc.com " Logon Failue:the user has not been granted the requested logon type at this computer. I am unable to join the client machine to domain. Administrator account is used to perform both the tasks. Second problems appears after a long time, the first problem started. Thanks Farhan A.
