So the sitcode is different and not the keybase code? If the sitcode is different then I can only assume someone has attached an old remote database to the remote? if thats the case, then you will need to recut a new remotedb.
If it is the keybase code and the remote is showing a higher value than the host then you can simply login to the Administrator - Users Profile - Sync - Right Mouse Click on the Keybase code value and select Increment.
However, if the remote is showing a lower Keybase code than the host then you will need to cut a new remote db.
