I noticed, I can't make any changes to the system configuration system folder (to change replication etc..), it always gives me a login prompt and then displays an access denied message. I am try to uninstall the first exchange server from the AD and when looking thru all the Public folders to make sure that all replication had been removed and i came across this folder that had replictaion but I am unable to remove it all ways asks for the username and password I give it that and it asks again it does this about 4 or 5 times then says access denied. Does any one have any thoughts on this could it be that when exchange is removed that this replication link gets broken then or does it have toi be removed before the Exchange removal. I all so have this othr problem that I cant uninstall exchange useing the cd or the add remove programs as it tells me that Exchange messaging and colaboration cannot be removed because one or more of the user mailboxes are in use and needs to be moved to a new server I have looked at the mailboxes the only thing that is there is the Syamtem mailbox the smtp mailbox and the Styem attendant mailbox I have all so looked in the ADSIEdit util for hidden mailboxes and have found none this one has me stumped any one with any info please let me know so I can finished the removal of this server and get my AD 2003 under way. PS I dont want to do a manul removal as I am not sure what will happen to my Current exchange 2003 server I dont want to bring that down in anyway, and another thing to note is this exchange runs good with the 2K server shut down but I do get a error on replication in the 2K3 queue that is trying to send the system hierachy to the old server I suspect it is the problem I have with the System Config folder.
