ISA in SBS - yes, it's secure
NOAH is a client server application used in medical facilities. It uses DCOM to communicate from client to server. New in ISA 2004 is a system policy that requires strict RPC compliance. You'll quickly find out which application comply and which ones don't now that this is by default requirement in ISA 2004.
To enable NOAH to communicate we need to not require it to adhere to strict RPC compliance.
1. Open ISA 2004 Management and select Firewall Policy.
2. Click on View and select Show System Policy Rules.
System Policy Rules detemine how traffic is allowed to get to the ISA server. We need to change what kind of traffic is allow to speak to the ISA server.
3. Right click on Allow RPC from ISA Server to trusted servers and select Edit System Policy.
4. Uncheck Enforce Strict RPC Compliance.
5. Click OK.
