I have a 3-person client who for some reason is unable to access a specific web site suddenly. They had this issue once before about 6 months ago and a lot of rebooting of the server and router eventually seemed to fix it.
The problem has returned abd I'm at my wits end trying to figure it out. I've tried accessing the same web site from a half-dozen other locations and it's fine. However, from inside this little network not only can I not get to the web site, I can't even ping the IP address. I've had them restart their router and I've flushed the DNS, but still no good.
Any ideas on what this can be?
Thanks in advance for any replies.
