I support 2 businesses with SBS server Lans and with both when I try to run liveupdate in IS 2009 on several different workstations they all come up with this error and fail to update. I can access the liveupdate sight manually and update these installations. All other functions on their internet connections work fine. Have tried the chat support but they are no help and have exhausted their scripts. Reinstall does not help… At wits end Any ideas Also IS 2008 worked fine–yes I know they changed the program completely but the connection parameters should not have changed??? thanks for your help…
