I have a client who is running sbs 2003 with Isa server 2004 installed on both the server & clients. Now one of the users is having an issue with the HMRC 2010 cd. Basically she is trying to view a p11 summary which is online but every time the application tries to view the p11 thru internet explorer i am getting a network access message. To me it would appear that the server is refusing to allow access. All clients have no issues accessing any websites & i am pretty sure there are no internet filter rules created.
Now i spoke with the hmrc helpdesk & they mentioned that the application uses port 443 (https)
Do you think the error is related to Isa blocking access?
