Thanks for your prompt and accurate responses!
The 4092 byte mades me suspicious of a new IIS overflow that was
not being caught.
The exploit you referenced mentions 296 x A's that rotate to drop
the code. That pretty much nails this scenario on the head!
Searches to my normal usenet groups and sec groups failed to find
this, so I appreciate your help in identifying the possible
exploit.
We are, or course, patched to this, but it was concerning me!
