I'll outline a few steps to obtain the info I need - if you are having intermittent problems then save this info to your computer somewhere.
Ok, let us begin.
1. Note down the time you are trying to access the site and the location. Also what error you are getting. Do you get a site not found error or does it just time out without the site loading. (With this info I can see if the site was very busy or not at the time)
2. Send me some ip details - go through the following steps.
Click Start
Click Run (this should pop up the run window)

Type cmd into the box and press ENTER. This should pop up another window

Into this window type
ipconfig /all
and press ENTER
A list of information should scroll down the screen. There should be an entry that says "DNS Servers ........... xxx.xxx.xxx.xxx"
In the same window type
nslookup surfing-waves.com xxx.xxx.xxx.xxx
where the xxx. is the entry following the DNS Servers
Press ENTER.
You should have something like this >

Next in the window type
tracert surfing-waves.com
and press ENTER
After 20/30 seconds you should see Trace Complete.
Next Right Click in the window and click Select All
Press ENTER
This has copied the information I need. Now you can send it to me either by email or PM - Don't paste it here.
I really appreciate any help with this - the sooner things are running smoothly the better for everyone.
Thanks
