Please
I Can Access To The File Server (2003) Through IT is IP (192.168.1.2) Address But I Can Not Access It Using The Server Name (\\Server01)

Please Advise ASAP

\\Server01 is not a valid name for a server - it is a windows internal name. The \\ part is a problem.

try using Server01 instead

Yes .. But Iam Taking About Local Server Named: Server01 With IP Address:192.168.1.2

The Problem It Does Respond Only When I Type The Ip

That means the server ('s name) is not known to your system:
1) Not referenced in DNS
OR
2) not in /etc/hosts
In which case, yes you are to provide its IP...
