Hi,

first you need to change the workgroup name on the windows 2003 server using below procedure

my computer - properties - computer name - change - workgroup


There is no potential risk in changing the workgroup name , all that you need to do is to change in the batch file on the clients which connects to the windwos 2003 shares.

i would like to give a little info about difference between hostname and netbios name

NetBIOS names is based on an older protocol and should be used within a LAN only and registers itself on that network everytime that PC is powered up or rebooted using LMHOSTS, broadcasts or WINS to provide resolution of a NetBIOS hostname to it's IP address. Thet are limited to 16 characters in length with 15 characters visible. NetBIOS names cannot be used as part of a doamin. The underscore character "_" is only used in NetBIOS names.

Hostnames TCP/IP based are resolved either with a static HOSTS file on your PC or from a DNS service. They typically are used as part of a domain. The hostname uses "-" instead of "_" as most DNS will reject this character and can be up to 255 characters in length.

please let us know if there is any confusion.
