I have ASP.NET 2.0 application which is hosted on a server with IIS 8.0 . The website was working fine, until some users reported a 404 error when they hit the URL. Now this happens only for a handful of users and they can access the website if they do it through the IP address.
I have tried flushing the DNS on their systems but with no luck.
Any ideas on how to fix this issue?
UPDATE: Some users have now complained about 400 error. This takes the total number of errored hits to 10.
Check if you can ping from pc that in not working by domain name and by ip number.
If it works only with ip then there is something with dns. You can try to use nslookup command on this pc to find more answers.
Some reason maybe not working pc is in some other network, maybe some firewall rule blocks it.
