I have only computer with DVD RW at my workplace and all co-workers
asks me to write data for them.
I decided to make Terminal Server from my Win Xp SP1 workstation, for RDP disk writing purpose.
I spend today patching winlogon.exe.

lsass.exe

winlogon.exe

I have Tested such solution (patching) in Vmware Win XP test env,
seems all working (2 RDP sessions and 1 interactive at same time). I'll test RDP disk writing tommorow at work, but
May be someone suggest more documented decision for my problem.
