ISA 2004 - RPC server Unavailable

I have just installed a new ml 350 g5 with win2003 server standard sp2 into my network to run as a ISA server. I have installed ISA 2004 sp3 everything works fine until i want to add AD users or groups to any access rule I get RPC server unavailable error. I can't even add a domain user to the local groups of the server. If i stop all ISA services and i then can add users to the local security group ie: domain admins into local admin group. I am aware that isa 2004 out of the box had this issue with win2003 server SP1 but the fix was to install ISA 2004 sp1 this does not apply in my case :( .
The rpc rule in the sytem policy is enabled also, i have even created my own rules to see if it was a faulty system policy but to no avail

Can anyone help please i am stumped

Make sure you have added a rule allowing trafic from internal & local host TO internal & local host.

I have done this and still no joy :(

Check the isa system policy rules - make sure that the rpc system rule is enabled and set.
Select monitoring - logging - click on start query.
What do you see in the log for the deny mesaages?
Which rule(s) is performing the deny?

The RPC rule does not deny it comes back a failed to connect error on that rule. The same happens if create the rule manually and disable the system policy rule the fail to connect goes against the manual rule
