I have an Access file to be shared by a couple of laptops, located anywere in the country. They run Office 2003 with XP. I need a replica in each laptop and the master on a server. Replication work fine on a LAN but I am unable to do it on the Internet server. Keep receiving the same error message: Invalid HTTP address. (Error 3685) The HTTP address specified is not valid for this replica set. The HTTP address supplied did not match any values in the field InternetAddress in the system table MSysTranspAddress. Is ther a way around this headache? besides aspirin? T.I.A.
