I'm guessing you send a large integer to function 0x30 in srvsvc via 
\\browser, and xpsp2 falls to basically the same bug. I haven't had time 
to test it yet though.
    

This is PoC from hume@nsfocus:

net use \\<target>\ipc$ "" /user:""
<this exe> -n <target> -x <0xb000000(size)>

That's all.
  
Looks good - I've found a sorta logarithmic stepdown on the memory works 
best...

Are you making <this exe> public? :>

I attached the rar to the first Email, but your list reject it. Now get
it from

http://www.opencjk.org/~scz/rpc_srvsvc_mmallocdos.rar

I'll delete it after one week.

By the way, FC_HARD_STRUCTURE should be FC_LGVARRAY, look MSDN.
No matter how, you do a great work.
