Sorry the block in question for ISA 2004, is:

Go to the rule that allows inbound web traffic and double-click it.
Click the "Protocols" tab
Click "Filtering"
Click "Configure HTTP"
Click the "Extensions" tab
And add wmf
I also have been adding emf as well.

I'm just not sure of how to do this on ISA 2000.

Also the only way I have been able to find to stop this attack on the
clients, using MS fixes, is to unregister the offending dll using. 

regsvr32 /u %windir%\system32\shimgvw.dll

Some sites also say to rename it as well to stop it being re-registered
by malware. This will stop the problem, but will stop certain things
working.

It might help to tell us what "block" you used in ISA 2004.

I have installed the "wmf" block to my ISA 2004 clients but I not sure
how to set this up for ISA 2000.
