dns issue

For an out of town client
Client has a website that I host at his full domain and also a LMS that uses a subdomain and that is hosted elsewhere.

I can see both sites at full domains but in the clients home he can't see either

He can get to both sites via IP address, and can publish to the full domain version that I host using the IP address in Dreamweaver

If he goes through a cloaking site he can see the sites at the full domains

I checked my hosting to see if the clients IP is blocked - but no, I don't know on the LMS version but have my doubts

Both sites are long standing and the issues only started this week

Domain is at GoDaddy

When client does domain traceroute to my server it works fine.

Client has a modem provided by his IPS and then a wifi router - he replaced the router to see if that would help

ISP has remotely re-set the modem.

Client has cleaned cache on computer and power cycled the modem and router

I have suggested he ask his ISP for new IP, any other thoughts?

It sounds like the DNS settings in the client computer are incorrect.  Have the client try and change/add Googles DNS and try.

Never thought of that.

Could you do me a wee screen shot so I can see what it looks like?

First, what is LMS?

Ask your client to use another device in his network first. If the other device can access your web site, there is clearly an issue with your client's computer (most probably wrong DNS servers or something in his host file, I would suspect the latter).

If the other device does also not work:

Ask your client to open a command prompt and execute the following command:
nslookup <your.domain.fqdn>

Open in new window

This will lookup your domain with Googles Public DNS. If this returns the correct IP addess of your domain, then ask the client to set his Network (either on his router in DHCP or on his computer) to use and as name servers.

It's probably the client's DNS server onsite.  It probably has a zone for HISDOMAIN.COM

If that's the case, open up DNS on the DNS server then create a new record in that zone called WWW with the public IP of his website.  Clear cache on DNS server and restart the DNS service then ipconfig/flushdns on the workstation and try again.

You can chanage it in the Network Properties which you can get to through Control Panel:
