<br><font size=2 face="sans-serif">Hello,</font>
<br>
<br><font size=2 face="sans-serif">When attempting to launch a tast in
WindowsXP 64 using the following:</font>
<br>
<br><font size=2 face="sans-serif"><b>mpiexec -delegate -hosts 1 hostA
hostname</b></font>
<br>
<br><font size=2 face="sans-serif">I receive the following error:</font>
<br>
<br><font size=2 face="sans-serif"><b>Launch failed: CreateProcess(hostname.exe)
on 'hostA' failed, error 5 - Access is denied.</b></font>
<br>
<br><font size=2 face="sans-serif">It would appear that in 64bit XP, Micros***
has implemented a new secirity model that assigns a user to an implicit
group upon login, and several binaries are no long accessible to the "Users"
group as you would expect in the 32bit version of Windoz. This is
the same security model that now appears in Windows2003 server after SP1.</font>
<br>
<br><font size=2 face="sans-serif">I am wondering what is the "correct"
workaround (<b>besides going to Linux</b>) to this problem. Or, is
this a bug with the Service Principal configuration in MPICH2? This
may be funny, but it's not a joke.</font>
<br>
