Sharepoint 2010 Site displays in Firefoxbut not in Internet Explorer 8
I setup SP Ent 2010 on Win 2008R2 virtual server with MSSQL2008R2. When I view the site I migrated from WSS 3.0 on the Win2008R2 host server and the 2008R2 virtual serving that has SP installed on it Internet Explorer displays the site in http and https no problems. If I go to any PC inside the office or outside of the firewall https will only work in Firefox but does not display display in Internet Explorer 8. I get a "IE cannot display the webpage" message. No error messages in event log on server or PCs. I even tried to create a test site in a new web application and content database to see if it was the migrated site and that does not work either. I am using the firewall in remote and routing services in 2003 SBS to port forward ports to the appropriate server (I did have ISA 2004 but it was causing too many issues so had to remove it, I hope to purchase a hardware firewall soon, but this is what I have to work with for now).
Any ideas??? I have 8 more sites to migrate and want to do it this weekend but need to solve this problem first. Using Firefox is not an option because important functionality is limited or simply not available in SP without IE. IE9 is still beta and IE7 would seem silly to go back to.
Thanks in advance
