I saw something similar and setting all the ms-rpc settings in SD to
monitor only allowed for the specific uid to pass, logs showed a monitor
log instead of the reject. With r60 we had to do an update to get the
option for monitor only for some of the ms-rpc checks.

DCE-RPC

scenario:
   
  hostA---FWA---Internet---FWB---hostB
   
  FWA is a Cisco Pix version 7.2(1)
FWB is running NGx R61 with HFA_01 running on IPSO 4.1 build 19
   
  hostA is a windows XP Pro. with Service Pack 2 and latest patches
hostB is Windows 2003 Service Pack 1 with latest patches
   
  I have site-to-site VPN between FWA and FWB.  VPN is up and running
and everything is allowed through the VPN tunnel.
   
  HostB is an Microsoft AD Controller, let call it nxia. When I tried to

add hostA into domain nxia, I am seeing this in the smartview tracker:

Protocol:                tcp
Source Port:            1257
Attack Name:           DCE-RPC Enforcement Violation
Information:             DCE-RPC Interface UID:
e3514235-4b06-11d1-ab04-00c04fc2dcd2
Attack Information:  UUID is not allowed through the Rule Base
   
  Furthermore, if I add another Microsoft Windows 2003 Enterprise
Server, 
hostC, behind FWA, and I tried to make hostC another AD controller of
nxia domain, it fails with the same error that I am getting above.
  It seems to me that NGx R61 (even with HFA_01) is having issues with
Microsoft AD to properly across the firewall.  
   
  I've been researching Checkpoint Knowledge base and from those SKs, it

  seems that Checkpoint has fixed this in HFA_04 or NGx R60 or HFA_01 in

  NGx R61.  But it is not working for me.  The SKs are sk25562, sk31245
and 
  sk31166.  I tried to modify the dcercp.def file but these knowledge
base is for 
  NG AI or NGx R60 and not R61.
   
  Anyone is running into similar issue like this one and how do you fix
this?  thanks.
