Below is an extract from the client log.
The client PC is going direct to the Internet for an update, it's not even looking for my internal Mirror???
Please provide a solution to this!!
Also my SOA mirror downloads over 100MB daily - this adds up i have had to disable daily updates becuase we only have 8GB monthly limit over here.
