It controls the stack for TCP/IP. TCP/IP Stack processing. CNTRL.EXE is a very important component of the stack. CNTRL.EXE provides threads for proper running of the stack. It provides a thread for each of the following:
- IP input processing
- TCP slow timeout processing
- Debug thread for IP
- ARP timeout processing
- Ifndis debug thread
- Watchdog thread for the adapter status
- Loopback IP packets processing
CNTRL.EXE is normally started from CONFIG.SYS with a RUN=statement. It should be the first program to begin executing when TCP/IP is started. CNTRL.EXE for Version 4 is different from that in the Version 2.0 stack
