Bad config, if you set up yor rules correctly you shouldn't have an issue.

Make sure that the proxy settings in IE are cleared before testing.

Yes; let's blame the script for failing to work with the crapplication that 
doesn't know how to acquire or use it.
With this (il)logic, we should blame the car for not functioning for someone 
who can't locate; much less operate it?

As I stated, since these crapplications don't understand the wpad process 
(defined in 1999, BTW) or the script (defined in 1998, BTW) provided by ISA, 
then you have no choice but to use the static proxy / exclusions method.

This is not an ISA problem; ISA is operating in accordance with public 
documents.

I believed citrix was using IE and IE was using WPAD to configure itself!
Now, if we cannot use BHO, AX control, Java crapplet, citrix or other "chained" 
crapplication, is there not chances that probably we are in front of crapWPAD 
system?

Regarding the IP address of the internal websites, here you have one: 
10.100.113.27
The ISA server and the client resides in the same subnet (10.200.*.*), the 
internal site resides on a different subnet that is part of the internal 
network (so no network relation here). Anyway the following is the worst part: 
the page the users are trying to access is the control for an IP KVM which is a 
JavaScript application.

So, since I know what are you going to answer and my company needs citrix, 
java, and all the other "crappy" things around. Which alternative do I have?

"..when he try to open a citrix application.." - it's these sort of details 
that make a world of difference to the questions you ask and the result you 
obtain.

Rule #1 for wpad-based configuration:
- you must NEVER assume that a BHO, AX control, Java crapplet or "chained" 
crapplication understands how to use the wpad script.  If the crapplication 
only works when manual exceptions are defined, then the crapplication doesn't 
know how to use the wpad script.  End of story; nothing ISA can do.

Rule #1 for wpad testing:
- because the browser caches the script for 1 hour, you *must* delete previous 
versions on the test client after making changes at via ISA manglement.

"..this is happening also on other internal websites accessed by IP and not 
residing on the same subnet of the ISA server.."
 - any chance you can provide a description of:
+ the IP address of the "internal" sites?
+ the network relationship for ISA with respect to the client and "internal" 
site?

OK, I already deleted what you mentioned down there.

Beside that: the user is accessing https://citrix.mscgva.ch Since I just 
noticed that the domain wasn't in my list, I added it and tried again, but with 
the same result. Attached you have the new WPAD file for you to take a look.
The weird part is that the user can access the website and login to it, the 
problem is when he try to open a citrix application.

As a comment, this is happening also on other internal websites accessed by IP 
and not residing on the same subnet of the ISA server (in this case no citrix 
stuff).

Good stuff - now; what is the exact URL they're trying to access directly?
I ask this because for two reasons:
1. you haven't stated this and it is important to how the wpad script operates 
2. you have some "interesting" entries in the "DirectNames" list:
  function MakeNames(){
  this[0]="*.interlink-intranet.net";
  this[1]="*/interlink-intranet.net/*";
  this[2]="warren.interlink-intranet.net";
  this[3]="us.interlink-intranet.net";
  this[4]="*.usa.msc-intranet.net";
  this[5]="lcs.interlink.bz";
  this[6]="*.interlink-intranet.net";
  }
  DirectNames=new MakeNames();

Specifically:
- "*/interlink-intranet.net/*" - this is not valid, since "/" is not a valid 
host or FQDN character - make it disappear
-  "warren.interlink-intranet.net", "us.interlink-intranet.net" - are already 
included in the first entry
- "*.interlink-intranet.net" - is a duplicate of the first entry and just 
wastes processing time - make it disappear

Clear the cached....
1- Did it
2- 1 file was deleted (but it was a copy I did on the desktop of the WPAD.DAT). 
So you can take it as cero files deleted
3- 0

Test your WPAD.....
1- did it
2- yes
3- yes
4- yes
5- yes
6- did it

The file is attached.

No; you will not see changes to the browser manual exclusion list when using 
automatic browser configuration.

Clear the cached auto-configuration files:
1. open a cmd window on the failing client 2. type del \wpad*.dat /s <enter> - 
how many files got wiped?
3. type del \wpad.dat /s <enter> - how many files got wiped?

Test your wpad mechanism:
1. open the browser on the failing client 2. enter http://wpad/wpad.dat <enter> 
- do you get prompted to save a file?
3. enter http://wpad:8080/wpad.dat <enter> - do you get prompted to save a file?
4. enter http://IsaIpAddress/wpad.dat <enter> - do you get prompted to save a 
file?
5. enter http://IsaIpAddress:8080/wpad.dat <enter> - do you get prompted to 
save a file?
6. close the browser


Attach your wpad to your response

The FC is configured to automatically detect ISA (WPAD) and it also has the 
"enable Web browser automatic configuration" option enabled, so I assume this 
last one is telling IE what must do or not.
When I check the IE Lan Settings configuration, it have the right proxy, and 
the right port (according to what I configured on ISA) but there is no 
exclusion list at all "I don't know if that is normal or not".

IE needs to get this information from ISA - have you defined any mechanism 
where the browser gets it?
WPAD or "configuration URL" are the ONLY times the browser knows what ISA 
considers "internal".

But there is a defined route on the Isa firewall. The server know exactly which 
one is the route to solve the requested address.

 

I guess the problem is the ISA firewall for some reason is not giving IE the 
right exclusion list, so IE no matter what will try to use the firewall. 
Because if I leave the same proxy configured on IE but manually add the 
exclusion it works.

But I have no idea how to fix this issue or where to search for the error on 
the configuration.

If the Firewall client machine sends to a destination that is not part of the 
defintion of the ISA Firewall Network on which the client is located, the 
Firewall client will remote the connection to the ISA Firewall to send to 
another ISA Firewall Network (such as the default External Network if there is 
no defined route on the ISA Firewall for the destination Network).

        What is the "ISA client"

         

        There is a FIREWALL client, SecureNAT (SecureNET) client, and a Web 
proxy client.

         

        THERE IS NO "ISA CLIENT".

                Good morning everybody (well, for most of you ;-) )

                 

                I have the following scenario:

                 

                Subnet 10.200.*.*(NY) and subnet 193.138.73.* (Geneva) both are 
internals and connected with a router no ISA in the middle.

                For the NY users the Internet proxy (ISA 2004 array) is on the 
10.200.*.* subnet and they have the ISA 2004 client installed configuring IE 
automatically.

                 

                The NY guys are trying to access a citrix server in Geneva with 
IE, the Geneva range was included on the NY proxy array as part of the internal 
network, also on the Web Browse TAB (internal network properties) so the proxy 
is bypassed when accessing that subnet and the subnet was also included on the 
routing table of both servers members of the array.

                 

                The point is citrix failed to open a desktop session.
They can reach the login page and even login, but session failed to open.

                 

                Now, if I disable the ISA client and manually add on IE the 
Geneva subnet between the exclusions, everything works fine.

                 

                Any idea of what can be happening?

                 

                Regards

                Diego R. Pietruszka
