How do I make a computer with static IP address visible on network?

My Boss's PC has recently become invisible on our Network. It is a Netware network using workgroups. His machine is running XP pro SP3. He can ping and see other systems out on the network but I can not ping his system or the see it in the list of systems on the network. He has a static IP address assigned to his machine,because of alert and the like that are sent to it each night. Also he has lost the ability to remote into his system form home. which he needs. He does NOT have the windows firewall enabled. We have tried reseting the IP stack that did not help. But the courious thing happen after we did that he got a dynamitly IP assigned which I was then able to see his system in the list of workgroup systems. When he assign the static IP again it disappeared.  I don't knowwhere to go from here any help would be appricated....

OK everyone that has be so kind to respond to my question, we have discovered the cause of my Boss's PC invisiblity. He installed at Cisco VPN Client just before this happen. Once he uninstalled it, well you know what the answer is, he is back to normal. I not sure how to reward the points for all you help. any suggestions?

Kieran_BurnsCommented:
what IP address does he have statically and what ip address does he get when getting one dynamically?
It's almost certainly going to be with using the wrong subnet / subnet mask, but if you could run an IPCONFIG /ALL  for both configurations we can confirm this

Going out on a limb here since I don't know Netware, but if you assign a static IP address to his system, I would think you will need to make a manual entry in DNS for an 'A' (host) record for that machine. Also, you should check to make sure there are no old entries in DNS for his machine name.
Also, the default domain name on his PC should be set to whatever the local domain is.

Don't enable file and print sharing.  That has nothing to do with it.

This can happen with bad ARP data.  Try clearing the arp data from the machine you are pinging from: arp -d *

Let me know if this does it.

DNS should have nothing to do with it unless you are pinging the machine by name rather than by I.P.

Hello

Rename your Boss computer, eq: from WORKGROUP to GROUPWORK  (dont restart yet)
Change the IP address, eq: from 192.168.0.2 to 192.168.0.22   (dont restart yet)

Turn off System Restore.
Perform a desk clean up. (not necessary)
Delete \Windows\Prefetch Folder.
Set Pagefile.sys to 0.

Restart twice(restart, boot-up, restart).

Rename again the workgroup of the group it belongs.
Change again the IP address it belong.

Turn on system restore again (if you want to)
Turn on pagefile.sys to system manage size.

Restart once(only).


Cheers!

Rionroc, I'm not trying to be thick, but what does that do?

Mark GoodmanNetwork AdministrtorAuthor Commented:
I seconded that question Rionroc....Please explain...Thanks.
So far all your suggestioned are great but system still can not be seen on the network. We checked the ARP on the system and even on the switch it was connected to. What else could block a ping request besides a firewall? Could our own Cisco ASA(Firewall) Block a internal IP address? We ran a packett sniffer on my boss;s system an did not see any ping request come in to the system.. We could see them when we pinged from his system. Thanks again for all your help.....

O.K. this should be pretty straightforward.  You switch the computer's IP from DHCP to static.  

If you are trying to ping the host by IP (not by hostname) from another machine, you should get there and back unless:
1. a routing issue - check IP and subnets.  If you want to post them, I will give it a glance, too.
2. Switch may be holding on to stale records.  Power cycle the switch.  Is this a managed switch or is there anything special about it?
3. ARP on the local machine (the one you are pinging from) may be getting the wrong data.  Check "arp -a" and make sure that the IP is getting matched to the correct MAC address.  Let me know if you need clarification on this.

rfportillaCommented:
It's not the ARP on the updated computer that needs to be checked.  You have to clear the ARP on the computer that you are pinging from.  

For example, if you modified the IP on computer A, and pinging from computer B, then clear the ARP cache on computer B.

I don't know if you are aware of this already, but I just want to make sure.

What happens if you try a *different* static IP address?  Perhaps there's a conflict on the network for the one you are using now?

Kieran_BurnsCommented:
Could you please provide the IPCONFIG/ALL details I asked for? Without this information, all the ideas are really just guesswork.

rionrocCommented:
Oh!  I'm sorry if you catch it wrong or I catch it wrong reading your post.

As far as I understand, that you have a problem about the network, between your boss computer and the others.


Good Luck!

The networking configuration looks fine to me excep that the you have different gateways.  This would not cause a ping to fail under the circumstances.  

Could you please provide an "arp -a" dump from the machine you are pinging from?

rfportillaCommented:
This doesn't sound like an IP conflict.  If you think it is, turn off your boss's computer (or disconnect it from the network), clear the arp cache on your computer again and try to ping the address to see if you get a response.  However, this doesn't sound like the case from the information you are giving.  

Otherwise, bring the computer back on the network and, from your computer and do this.  Just ping 10.1.3.27 and then run the arp -a command again.  If you don't see a listing in there matching 10.1.3.27 to 00-13-72-8A-D6-44 , then broadcasts are not coming across.  Or the routing is messed up still.

When the local routing on the PC sees that the foreign IP address is on the local network, but not in the ARP cache, it sends out layer 2 broadcast requests asking for this information.  If it is not on the local network, it contacts the gateway.  This is the first scenario, broadcast issue.  Do you have VLANs configured on your switch?  You have a layer 2 switch which means that it uses ARP information to quiet down broadcast traffic as well as unicast.  If these other things haven't worked and you haven't rebooted the switch, please do that.  If that fails, check the switch configuration.  That seems to be the only other thing that makes sense.

As a test, you can add a static entry for your boss's PC on your computer using:
arp -s 10.1.3.27 00-13-72-8A-D6-44

Hello

The steps I've given to you is called troubleshooting, theres no harm or hard in trying in that kind of method.

Cheer!
Good Luck!

rfportillaCommented:
Rionroc, it just doesn't make sense.  Troubleshooting is limiting the scope of the problem so that you can fix it.  I have never heard anybody suggest what you suggested for fixing a networking problem and so I wanted to know what your reasoning was.  That sounds like a shot in the dark.  Do you have any technical reason to support your "steps?"

Kieran_BurnsCommented:
Strictly speaking we did not answer the question, so I would go for (and be happy with) a refund. I think as long as the answer stays as there have been some very good suggestions (from others!) while troubleshooting the issue
I'd also removed Local Admin access for your boss while you are at it. :-)
