Forefront /NOMOM cannot update

If you have a single server running Forefront and not having access to your WSUS for updates (ie: an ISA server in a DMZ) you need to install the AV software with the /nomom option :
clientsetup /nomom
But it won't update automatically by itself.
You need to run Microsoft update and enable updates for Microsoft products in addition to Windows updates.

Cannot enable "CLR enabled", needed after Forefront update (WSUS)

After a Forefront update on my server (WSUS + Forefront), it complained about an SQL option to be set (CLR) but there is no way I could set it up.

Start Forefront client security console :
An update for Microsoft forefront client security has occurred which requires the configuration wizard to be run again

Verifying settings and requirements -> failed

Log results :

I tried through the SQL Surface Area Configuration to set CLR to 1, but :

Failed to connect to server localhost\MICROSOFT##SSEE. (Microsoft.SqlServer.ConnectionInfo)


Here is how to fix it; open a command prompt and execute the following command lines :

osql -S \\.\pipe\sql\query -E -I
exec sp_configure 'show advanced options', 1
go
reconfigure
exec sp_configure
go

It shows :
clr enabled 0 1 0

Try to set clr enabled to 1...

exec sp_configure 'clr enabled','1'
go

Then :

exec sp_configure
go

It shows now :
clr enabled 0 1 1

Start again your Microsoft Forefront Client Security Console and it will go through all the update install process.
