Hi,
I am having a problem, not sure if its my computer or my isp and not sure what to check.
The problem is when I try to access my web site from my home computer, it doesn't always find it if I use the www in the addy. Other times it finds it with the www but not without it! Sometimes doesn't find either and sometimes finds both. I can access other sites without any problem, and others can access my site without any problem. Has just started happening past week or so.

Have run some programs to try to fix ie:
Symantec System Works One Button Checkup
Symantec System Works Disk Doctor
Symantec System Works Win Doctor
Symantec System Works Anti Virus (full scan)
Ad-aware Full Scan
Hi-jack this

Sometimes one of these seems to fix temporaraly (but doesn't say it has found anything) until I reboot computer, then problem returns.
Have had someone look at my registry but can't find anything obvious in there causing problem.
Have also checked DNS report and all is fine there.
Done a tracert and here are results
C:\Documents and Settings\Family>tracert fra-designs.com

I am asking my ISP provider now too but so far no luck.

Not sure what else to try or where to look now.
Thanks
Ange

Does it always find it if you use the IP address directly? Sure sounds like a misbehaving DNS.

Try using the following temporarily as your DNS servers:

4.2.2.1
4.2.2.2

Internet Protocol (TCP/IP)/Properties/General tab

Thankyou for that, I will pass this onto my brother who knows more than me and get him to check it out for me.
I heard back from my ISP provider and he says everything seems to be alright from thier end. He suggests looking into the web server for my site.
Will check that too.
Do you know if there are any settings on my computer that could be doing this or a virus that may have done it?
Thanks
Ange

Enter the IP address (69.50.177.114) in your browser's address window just as you would a domain name.

Does that ALWAYS bring up the site or does it also fail occasionally?

If using the IP ALWAYS works, then it is definitely a DNS lookup problem.

See http://www.bleepingcomputer.com/tutorials/the-domain-name-system/ for a tutorial on DNS.

Most ISPs use multiple DNS servers, and the actual server you get will be somewhat random. If the ISP has 3 servers with good info, and one with bad, then you will get bad info 25% of the time.

Changing to a different know set of DNS servers as I suggested will help prove/disprove that possibility.
