OK.
Phoned ISP again and after several 'ipconfig /all' tests etc. It turns out that my server is pointing me to an incorrect DNS Server address!
My ISP changed their DNS adresses without telling anyone?!?!? And the date they gave for when this happened coincides with the date that we could no longer accress our own domain!
Anyway long story short we need to change the DNS address that the server is pointing to...but can we find that option anywhere...NO.
Am connected via web browser and under 'review configuration' it shows DNS address as 192.168.1.1 which is the Servers address...eaaaarrrggghh WTF WTF WTF.
How do i change the server over to direct DNS queries to a different address.
BTW. I Changed the settings on local machine to point to DNS address given by ISP. Press repair connection so disconnects and reconnects...connects ok and can ping my domain now (
www.cross-channel.com) and the correct IP address of the domain now being returned with 100% success. Then after 1 minute connected i get limited or no connectivity...take settings off local machine and connect ok!
Conclusion.
I HAVE TO UNDOUBTIDLY WITHOUT QUESTION HAVE TO CHANGE THE DNS ADDRESSES ON THE SERVER...according to my ISP anyway...HOW DO YOU DO THIS????
please help before i go mad!
Many thanks
Andrew
