This article was previously published under Q123077

## SYMPTOMS

After you install Microsoft 32-bit TCP/IP and issue a PING.EXE, ARP.EXE, NBTSTAT.EXE, NETSTAT.EXE, or ROUTE.EXE command from a real mode MS-DOS command prompt, one of the following problems occurs:

- The machine reboots
  -or-
- The machine stops responding (locks up)
  -or-
- The system generates an EMM exception error

## CAUSE

Because Microsoft TCP/IP-32 is an NDIS3 protocol, the utilities must be run from within Windows for Workgroups while the protocol is loaded.

## RESOLUTION

To correctly use the TCP/IP utilities, choose the MS-DOS Prompt icon to open an MS-DOS window within Windows for Workgroups, and then run the utility using its proper syntax. For example, to run the PING command, type the following:

c:\windows>ping 127.0.0.1
