SBS 2008 Exchange Transport service Stops

I am not aware of any requirement to stop services to remove Forefront because it should stop them automatically. If the service is stopping then something should be logged in the event viewer - there are other reasons why the service will stop immediately.

i found some more info saying try and go through the registry and delete anything to do with forefront and that still didnt work
I also have SQL 2005 express cause it comes standard with SBS but i had to install SQL 2008 for a program that is required could there be a conflicked ?
i have the event ID error messages there are 2

Error number 1 ---- EventID: 16023

The creation of an agent factory for the agent 'FSE Routing Agent' failed with error 'Failed to create type 'Antigen.AntigenRoutingAgentFactory' from assembly 'C:\Program Files\Microsoft\Exchange Server\TransportRoles\agents\FSEAgent\Bin\FSEAgent_8.0.685.dll' due to error 'Invalid agent assembly path.'.'. Verify that the corresponding transport agent assembly and dependencies with the correct version are installed.

That looks like Forefront didn't uninstall correctly as Antigen is Forefront's old name. I would be doing the reinstall, reboot and uninstall method if it was me.

Simon.

got to be another option

open command shell
and check if you see AV sink

get-transportagent.
copy and paste the links here....

if you see antigen sink there.. do this...
disable-transportagent -identity XXXX
here xxxx will be the one agent u see when u do that get-trnasportagent command...
then restart the transport service...

antigen is for exchange 2003 or sbs 2003.
you need to have forefront..thats for sbs2008 and exch2007
let me know the results

ill let you know had to finish for today ill try in the morning

So you would prefer to spend hours playing around with the registry etc to remove a product, rather than simply getting hold of the original installation files and installing again.

Oh well, your time you are wasting.

I will unsubscribe from this question now.
