Hi All I am currently in the progress of migrating from exchange 5.5 to exchange 2003, I am currently trying to move my 5.5 mailboxes across a administration group/site to my new exchange 2003 server. When moving the mailbox from a 5.5 server to 2003 it advises that the Directory Service/Information Store (DS/IS) consistency adjuster patch is installed on all 5.5 servers which I have done but during the process it checks all 5.5 servers to verify this patch has been installed and it reports 2 servers that the patch was not installed on.I have verified that the patch installed successfully. As it report the patch has not been installed I am unable to move mailboxes. Has anyone seen this problem before? Any advice would be appreciated.
