He probably needs to start with the basics. Can he ping and/or tracert Ozarkanglers.com?
To try click Start, Run, type CMD... then type ping ozarkanglers.com and or tracert ozarkanglers.com at the command prompt.
The results will tell if he can send and recieve packets to the server as well if he is being given the proper address from his DNS server. The results determine the next step in troubleshooting.
If that fails, he should check the contents of the hosts file located at C:\WINDOWS\system32\drivers\etc to make sure there is not a static entry for ozarkanglers.com or that he is getting routed through a proxy, under normal circuimstances it sould be empty except for commets (prefaced with #) and the entry 127.0.0.1 localhost.
It would'nt hurt to also download and Spybot search and Destory and do a scan for malware....
HTH,
