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" <Enter> 3. say "OK" to the next to popups 4. type (no quotes): "net stop isactrl /y" <Enter> 5. wait until all the services are stopped 6. type (no quotes): "net start w3proxy" <Enter> 5. wait until the web proxy service starts 7. If you'e running Integrated or Firewall mode, type (no quotes): "net start fwsrv" <Enter> 8. If you're running RRAS on the ISA, type (no quotes): "net start remoteaccess" <Enter> 9. if you're running Cache or Integrated mode, type (no quotes): "net start w3schdwn" <Enter> ..that should fix you. If not, then you may have to reinstall ISA from Add/Remove Programs (registry corruption).
