ISA Server Error - 19.Aug.2004 6:05:00 PM

Hi Guys,

Since last week I'm running ISA 2004 and all was running fine just until now. I started my ISA mmc and I received the following error message:

ISA Server Error
- Refresh failed

- 0cx0040305
The string is emtpy or invalid

The result is that I don't see my firewall rules anymore (they still apply though!). Also when I change my view settings to show the system policy rules, again nothing happens.

Did anyone see this yet? Any idea what I can do?

Hi Geert,

1. Is this on the ISA firewall or on a remote console?

2. What software is installed on the ISA firewall outside of the ISA firewall software?

3. Have you restarted the firewall?

Hi Tom,

Setup is as follows:
Windows 2003 standard server
ISA 2004 standard

This box only serves as a firewall/proxy for my internal network.

Logged on to the console or via terminal services showed the same issue.

I even tried a reboot of the server with no success, same problem.

Then I tried a repair of ISA but that one bounced also. I had to remove ISA completely and reinstall before I got it to work again. Luckily I had a backup of my config, now I know why that's important ;-)

So all is working again, but I don't know the root cause.

ISA Server Error
- Refresh failed
ISA2004, might still relate somehow to dcom authentication level. See my post about the same error I had with ISA2000

ISA 2000
I did have the same monitoring > alerts > refresh failed error, and just today I found a nice fix that worked with my servers:

I figured out that this problem is due to dcom configuration and authentication level:
Run dcomcnfg.exe > applications tab > FPC class (1) and (2), properties, general tab > change authentication level from default to connection > alerts will work with local session as well as remote session. Im not sure if you can change this level back to default, but I think this is better workaround than reinstalling isaserver (that didnt work for me, had still the same error)
