/*
* PROGRAM NAME: SADMIN32
* ------------
*
* What this program does: This program executes a command on a remote
* server. The command to be executed on the remote server is passed
* as a command line parameter to this program but it must reside
* on a disk visible to the target server.
*
* REQUIRED FILES:
* --------------
* SADMIN32.C - Source code for this program
*
* REQUIRED LIBRARIES:
* ------------------
* NETAPI32.LIB - Netapi library (in \IBMLAN\NETSRC\OS2\LIB directory)
*
* NetAPI32 functions used in this program:
* ---------------------------------------
* Net32ServerAdminCommand
*
* HOW TO COMPILE THIS PROGRAM:
* ----------------------------
* icc /Gt+ /DPURE_32 /C sadmin32.c
