This may be a Windows 2000 question buy figure I would also try in Exchange. My Exchange 2000 Server has been working fine up till a couple of days ago. Now I can create a user in Active Directory and the user creates but does not create a mailbox. Also I have a couple of users that I had deleted out of AD and when I went into System Manager to delete their mailboxes from Exchange it times out after about 2 minutes and will not delete. I can login fine to the Domain and can create users in the Domain but nothing will create in Exchange. I am thinking something is not right within AD and Exchange and maybe DNS. I just do not know what to do without wiping something out that I shouldn't. Any suggestions or tips would be greatly appreciated.
