PROBLEM:

• When installing Isa 2006 on Server 2003 R2 the install fails on ADAM install. The error is: “setup failed to install ADAM”. This error pops up towards the end of the ISA install. This occurs if you have a server 2003 R2 with SP2 installed.

SOLUTIONS:

• Work Around 1 - Copy the contents of the ISA 2006 disc on the local hard drive. Put the Server 2003 R2 disc in the ROM drive and launch the ISA 2006 install from the contents on the local hard drive. The install should complete with no errors this time.
• Work Around 2 - Install Windows 2003 Server R2 with SP1 then install ISA 2006 then install SP2. Doing the installs in this order should avoid this ADAM error.

I ran into an issue with my recently deployed ISA firewall. It was blocking
any STMP incoming traffic. This made it so my Exchange users could send 
email just fine but could not receive any incoming email. I checked the 
Event Viewer and saw this:

Event Type:        Warning
Event Source:    Microsoft Firewall
Event Category:                None
Event ID:              14090
User:                     N/A
Description:
The server publishing rule Exchange POP3 SMTP Server, which maps 
192.168.5.32:25:TCP to 183.9.124.120:25 for the protocol SMTP Server, was 
unable to bind a socket for the server. The server publishing rule cannot 
be applied.   

To resolve this I had to make a simple change to my Exchange SMTP rule in ISA. First go into the ISA management console. Find your SMTP rule for incoming traffic. Right click on it.

Select properties. Then go to the “To” tab. Be sure to select “Requests appear to come from the ISA Server computer”

Click ok and then apply the changes to ISA. This should fix the issue and you will not see the warning in event viewer anymore.

My clients on my network could access FTP servers behind our ISA 06 firewall but they could not create or delete anything on that FTP. I checked to make sure the permissions on the FTP were setup correctly. I narrowed it down to ISA blocking Incoming FTP traffic coming back from the FTP servers. I did some searching and there are many issues out on this. Others issues vary slightly but I did find something that worked for me. I setup the below rule on ISA.

The Issue:

We requested a new certificate for our website from a CA. We applied the certificate on the Internal IIS6 web server. I then exported the certificate including keys and imported onto our ISA 2006 firewall.

I then went into the publishing rule for our website and updated it with the new certificate.

When external users went to our website using https they got the following error:
Error Code: 500 Internal Server Error. The target principal name is incorrect. (-2146893022)
