Hi there

I had to re-install a ISA 2004 Firewall machine and for various reasons went back to Windows 2003 without SP1 i have since installed SP1 and all is well except i can no longer RDP to the ISA server to administer it. I know there is a fix for this but i can't find the KB article, can anyone help by pointing me in the right direction?

I am certain i found the article on here a year or two back but lol the ISA server HTTP filter stops me from using the search facility for the forums.

Thanks

Did you also SPack ISA? ISA on W2K3SP1 must be SPacked.

You should go into the TSC and specifically assign the RDP listener to the NIC of your choosing.

Hi there

Thanks for that i'll take a look at the TSC settings next time on site (although it worked fine before) also from memory does this now mean i can only have RDP on one of the Network interfaces? I just had a funny feeling a registry hack was required to fix this the last time a i had the problem.

PS I have ISA 2004 SP2 installed.

Hi, i was just wondering if you had found a solution to this problem as I am in the same boat w2k3 sp1 and isa 2004 sp2 and I am not able to rdp to the server. If it helps, I did realtime logging and received "FWX_E_Abortive_shutdown"

thanks
Am

Thanks for your reply, I believe you are talking about the terminal services but I'm at a loss for the TSC - please excuse my naiveness.

thanks

Obviously not enough sleep,
I did assign the listener to my nic, in the "live" logs I noticed the same "...abortive_shutdown" as well as an attempt to RDP to the external nic

thanks for your patience

TSC = Terminal Services Configuration
unless you are publishing it for access from the internet, I would think the listener should be applied to the internal NIC.

If not published, why would the request show up on the external NIC? Do you have a DNS entry for the external NIC?

Hi, I have selected the internal nic exclusively, yet I still get attempts on the external. There is no DNS entry for the external nic.
I have tried the following troubleshooting ideas:
I have been able to telnet on 3389 to the server
I have modified the sytem rule for mmc to allow connections from "internal" as well as my defined enterprise network
I have created an array Firewall rule to allow RDP to no avail

I am able to remote from the ISA to any other server in the network, and of course to itself. but I still get the same "...abortive_shutdown" error when attempting from other servers - even those with supposed "all outbound" set to "allow"
So far, sol...
thanks for your help
