How do I use the Windows 98SE DOS ping command to ping a particular port
number? I need
to test to see if my ISP is blocking certain ports.

call them and ask them.

For example, if I want to ping Port 25 on SMTP.MYSITE.COM from my
computer. I tried

C:\ ping smtp.mysite.com:25

and it spits an error.

Thanks to anyone that can help!!!

This is the syntax of the PING command

As you can see, PING doesn't support what you want to do.

Try

TELNET SMTP.MYSITE.COM PORT 25
