One solution might be to set the Agents to detect and use IE proxy settings and also add the McAfee http repositories into IE proxy exceptions.
I came accross the proxy settings yesterday arvo so i tested this but because it was checking 5 repositories before going out to McAfee http over an ADSL 1 test line it appeared like it going was failing. I tested again this morning and after about 25 minutes it was successfull. I also tested this by disabling the LAN repositories and using McAfee http only and this took about 5 minutes.
Appreciate your responce
