Cannot connect to IIS7 Websites
After switching our cable modem to a new brand we are no longer able to connect to state medical websites running IIS 7. The reason for the modem brand change was that we experienced multiple outages per week with the SMC modem spectrum had provided. After the change all of my users reported issues with various state sites running IIS 7 however the internet in general works great.
I have 40 users a 2012 std DC with DNS and DHCP roles enabled, I have cleared the DNS cache upgraded the firmware on my Firewalls (ubiquity edgemax lite) also the connection is a 100x7
I do have an on prem exchange server as well.
Here is the error I get from the IIS7 report generator
Report Viewer Configuration Error
The Report Viewer Web Control HTTP Handler has not been registered in the application's web.config file. Add <add verb="*" path="Reserved.ReportViewe rWebContro l.axd" type = "Microsoft.Reporting.WebFo rms.HttpHa ndler, Microsoft.ReportViewer.Web Forms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd808 0cc91" /> to the system.web/httpHandlers section of the web.config file, or add <add name="ReportViewerWebContr olHandler" preCondition="integratedMo de" verb="*" path="Reserved.ReportViewe rWebContro l.axd" type="Microsoft.Reporting. WebForms.H ttpHandler , Microsoft.ReportViewer.Web Forms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd808 0cc91" /> to the system.webServer/handlers section for Internet Information Services 7 or later.
Also the sites return 404 often while browsing the site and a refresh cures the problem

The error is telling you exactly what to do.
- or -
I suggest doing the first option since it is a site level resource and the second option is an IIS server reconfiguration and would potentially affect all sites and services running under the IIS Server scope.

After troubleshooting I entered a static DNS server provided by the new ISP bypassing the DNS server onsite in one of the clients workstations and ran IPCONFIG /FLUSHDNS then cleared all browser cache. I entered the site in question and everything immediately worked. I then changed the static DNS on the workstation to 8.8.8.8 this is the primary forwarder I use internally, and I repeated the aforementioned cach clearing sequence. The site in question Immediately went back to behaving poorly. I have set new DNS forwarders in my internal DNS server and all is working.
From your error it seems that you are facing issue of handler mapping.
Open IIS>> click on handler mapping >> right hand side find the revert to parent >> do that.
Once try this and let me know if you still face issue.
Good Luck!!!!!!
