I just installed Microsoft ISA server and suddenly I am getting a weird result when I try to ping an internal IP. Name resolution works fine, and pinging by name resolves the name to IP just fine. But if I try to ping by IP i get the following result:

>ping 192.168.084.1

Pinging 192.168.084.1 [192.168.68.1] with 32 bytes of data:

Request timed out.
Request timed out.
Request timed out.
Request timed out.

Ping statistics for 192.168.68.1:

Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),

I pinged 192.168.084.1,
but it looks for 192.168.68.1.

The problem is with the leading zero in the 3rd octet of the IP address "Pinging 192.168.084.1"

The .084 portion gets translated (I can't remember how it modifies it offhand) and it comes up with the .68 after it is converted.

Try pinging the address without the zero, "ping 192.168.84.1" and it should work without a problem.

Good luck!

You are exactly right. I never really realized I was putting the leading zero in when pinging. After installing ISA, and configuring filters and such I got in the habbit of putting in the leading zero so the cursor would automatically moce to the next section. It doesnt matter if its entered there, BUT it does when pinging from a DOS prompt. Thanks

I don't know if you copied your LAT straight from ISA or not but on the question itself on the 4th line of your lat you left out the 2 in 192. Also you have overlapping ipranges in your LAT and I've seen that cause some problems in the past.
