DNS Mapping problems

Can someone explain to me these issues:

1- I have computers in the network that I can ping by IP but not by name.
2- I have some servers that can be pingged by IP or Name from some workstations but not from other workstations unless I unclude those servers in local host file.
3- If I delete the local host file, would it be created next time the computer reboots.

Thanks.

This could be one of a few things.  What are the DNS/WINS servers of the two different workstations?  And are all the servers and workstations on the same local subnet?

DNS server are windows 2003 servers and workstation and servers are in 2 different subnets.
but even within the workstations subnet I can ping a orkstation by name but only by IP

What do you mean by "I can ping a orkstation by name but only by IP"?  This sounds like you can ping them by IP and name.  
I need a more information in order to help you troubleshoot the problem.  
Do the workstations receive their DHCP from a Windows 2003 server?  
What is the IP address of your DHCP servers?
What is the IP address of all your DNS servers?
What are the DNS servers on the workstations?

sorry I meant  "I can not ping a workstation by name but only by IP"
workstations receive IP through DHCP
Workstations are in the range of 10.21.x.x
DHCP server is 10.28.1.10
DNS server is 10.28.1.20

Check the DNS server and see if the forwards are there to resolve name to IP address.  It sounds like this is not getting updated

I checked DNS and all machines have their A and PTR records.

I just noticed that your DHCP & DNS servers are different.  It will work better if the DHCP server and the DNS server are the same.  This way your DHCP server correctly updates the DNS server.  You can have the two DNS servers replicate if necessary, but for most networks having these on the same machine works great.

DHCP is configured to updates clients record in the DNS server.
If 2 DNS are not  domain controllers how would they replicate thier zones?
