I have a SBS 2003 server that is getting USERENV error 1058 and 1030 referring to not being able to find a group policy object. If I check the policies folder, I do not see the GPO that it is referencing in the error. Also, when I create a new user, the Exchange Mailbox does not get created even though I check the box to create it. Then I get these errors in the App Event Log. So I am wondering why SBS 2003 needs a GPO to create the mailbox? Is there a way to create the mailbox manually? If it does need a particular GPO to create the mailbox, how can I rebuild the default GPOs for the SBS server?
