Anyway with the help of Tooki I finally did manage to connect to the internet with the IP address corrected.
Now i'm trying to connect to our Exchange Server using Apple Mail prog.
The I manager has given me all the numbers. The following is what I entered
Incoming Mail Server: 192.168.100.20
Account Type: Exchange
Outgoing Mail Server: 192.168.100.20
Outlook Web Access Server is XX.XX.XX.XXX/exchange
When I press ok it says
Error
The exchange server "IP ADDRESS HERE" is not responding. Check your network connection etc etc
I have pinged the address and it is there. Any clues
