Network discover devices

Make sure the IP address is consistent with the current subnet.
Can you ping other computers at all?
Can they ping this computer at all?

Check its firewall.  Maybe it doesn't know which network it's on.  This can happen if the firewall program was installed while the computer isn't on the current network.

Turn off the firewall and see if it matters.

The other computers can see this one but it can not see the others.

you put me on th rright track. "network discovery" is turned off. However when I try to change it it will not save.

go to the safe mode and turn it on then save , and recheck,

are the associated services running well? the services are:

* Computer Browser
* Network Connections
* Network Location Awareness
* Network Store Interface Service
* SSDP Discovery
* Workstation

moreover, do you have the similar issues here?

When I try to start "computer browser". I get  "error 1060 the specified service does not exist as an installed service"

the Computer Browser service is dependent on Workstation and Server services. make sure the two services are standing well:

*  are the two services correctly bound to the network card(s)?
*. can they start?
*. if not, are the required executable files are that the right folder?

Thank you comments. I've  not had the free time to work on this problem. I just installed an extra printer  that I had in the office directly to this work station which lets me print.  I still want to fix this but other projects needed to be put ahead on this issue.  I hope to get to this ASAP. If you close the question it will still be available?  - Not deleted?
