But he also says he can't ping outside the network by IP from the iSeries. I
think the "IT guys" put the iSeries in a "sandbox". But one problem at a
time suppose...

You can run NSLOOKUP on the iSeries. At the prompt, type some well known
website. Here is what I got for yahoo.com.
> yahoo.com                                       
  Server:  ldap.milwaukeevalve.com                
  Address:  192.168.1.1                            
                                                  
  Nonauthoritative answer:                        
  Name:    yahoo.com                              
  Addresses:  66.94.234.13, 216.109.112.135       
                                                  
The "Server" is where I am looking up addresses. The nonauthoritative answer
is what ldap thinks is yahoo.com. If it fails the first time, try it two
more times to make sure that it isn't slow in pulling up the addresses and
timing out itself. Three failures in a row for a well known website will
almost certainly mean a problem with the DNS setup. 

If you fail this test, look at CHGTCPDMN (F4) and see what is set for domain
name service. There could be more than one address in there. If there is,
you should go back to nslookup (F4) and use the second address as the DNS
server (NSLOOKUP DMNNAMSVR('192.168.1.2')). Continue until you run out of
addresses. 

If you failed to get an answer on all the DNS servers set up on the iSeries,
it is probably time to change the DNS server list. Use CHGTCPDMN to put in
different DNS servers. It should be the same DNS Servers you see if you type
IPCONFIG /ALL from a PC inside the company. Of course, talk to the IT guys
before changing anything.

When you get the DNS issue resolved, get back to us with another debug.
