local hosted site not working?

[Kenny]

hi all, i have just turned on my virtual server that i have setup dns and iis earlier on. i have just purchased a new domain and have setup the dns information on godaddy and my server as well as setup the iis record and everything.

i am trying to connect to my website which is ctos.co.uk

if i try to connect from a computer or device on my network "which is the same as the server" then i cannot access using either my external wan ip address or the address of ctos.co.uk.

if however i try to connect using a proxy server, dns checking website or use my mobile phone "not connected to wifi" then i can connect strait away.

i have even tried using my mothers internet connection and she is using the same provider and she lives under neath my flat so we would be connected to the same UBR for virgin and use the same name servers ect.

do you have any idea whats going on? anything i can try

by the way i cannot access any of the other sites that i have hosted on my server either.
if i check out ping ctos.co.uk i get the correct ip address on my computer "my wans ip" i have tried flushing dns too
