We have a windows 2016 web server which runs RDP, Database Server & IIS.
We have added the applications, Configured the database able to connect to all of the servers services as expected (Windows Firewall configured to permit WebServer/RDP access etc)
We install Symantec Endpoint Protection 14 on to this system. After this we are no longer able to connect to these services.
Assumed that the Symantic Endpoint Firewall was the issue so we configured the Endpoint Protection firewall to permit Port 80,443 and RDP – First Rule in the List.
We are still unable to access these services over the network.
We therefore disabled the network protection. Still unavilable.
Disabled all aspects of the Symantic Endpoint protection. Still Unavilable.
Uninstalled Symantic endpoint protection. Services are running but are Still Unavilable. Checked the windows firewall for incoming rules which are present.
This is a virtual machine so we revert to the backup snapshot we took – Services are now avilable and working. Install Symantic again, Same symtoms.
Is defiently SEP which is causing the issues and its not a configuration issue with the firewall as proven by the uninstall of symantic still causing the issues.
At all states we are able to ping the system and the system is able to access external/internal services.
If anyone has any suggestions it would be apprivated. I’d raise a case but waiting on symantic to add my license details out my symantic account.
