I have a database program (using SQL) that I am trying to communicate to on the SBS 2003 Server. When I go onto my client PC and open the database program up from the web it opens fine however some instances I get a 502 error saying the ISA server denied access.
I am running ISA 2004 on my SBS 2003 Server Machine and Windows XP Pro SP3 on my client PC logging in online using the latest Firefox update.
How can I configure the ISA server to allow access? Like I said it doesn;t always trigger the error some times the connection works just fine.
