DCOM Error Related to SMTP Message Screener
The ISA firewall's SMTP Message Screener is pretty cool. Its not a full-fleged spam whacker, but it provides a nice first line of defense against unwanted email. One thing that was a bit problematic with the ISA 2000 firewall's SMTP Message Screener was that it depended on DCOM messages being passed between the SMTP relay with the SMTP Message Screener installed and the ISA firewall machine. You don't see this problem if the SMTP Message Screener is on the ISA firewall itself, but you do see it if it's on another machine.
If you see an error that looks some like this:
DCOM got error "General access denied error " from the computer proxy
when attempting to activate the server:
{0820D243-0B18-4B0A-88F0-D857F0C91E62}
Then you'll benefit from this cool fix from Jim Harrison:
That GUID represents the VendorParametersSet processing DLL in ISA.
Try this:
1 - open a cmd window and navigate to your ISA installation folder.
2. type (no quotes): "regsvr32 vps2.dll"
3. say "OK" to the next to popups
4. type (no quotes): "net stop isactrl /y"
5. wait until all the services are stopped
6. type (no quotes): "net start w3proxy"
7. wait until the web proxy service starts
8. If you'e running Integrated or Firewall mode, type (no quotes): "net start fwsrv"
9. If you're running RRAS on the ISA, type (no quotes): "net start remoteaccess"
10. if you're running Cache or Integrated mode, type (no quotes): "net start w3schdwn"
As always, Jim dredges up the best fixes in the biz!
Thanks!
