JEBO 0 Posted August 27, 2018 Share Posted August 27, 2018 (edited) Hi! We have a customer with a strange issue, if ESET FileSecurity is installed on the server, their webapplication based on Silverlight do not work, we get an exception stating "CommunicationException" (SFxServerDidNotReply). It does not matter if we stop realtimeprotection, webprotection and phising protection, the exception gets thrown either way. ESET does not display any information in "Detected Threats". The only solution is to uninstall ESET and reboot the server, then the application works again! Any suggestions?

Administrators Marcos 5,070 Posted August 27, 2018 Administrators Share Posted August 27, 2018 Did you also try temporarily disabling protocol filtering? What version of Windows Server is it? Could you try upgrading to EFSW v7? Link to comment Share on other sites More sharing options...
JEBO 0 Posted August 28, 2018 Author Share Posted August 28, 2018 Thanks for the suggestions, we had to add the IP-address of the server running the Silverlight webapp to the list of Excluded IP addresses in the protocol filtering section. Case closed! Link to comment Share on other sites More sharing options...
