Trouble accessing local network when Internet is on.

[phani kumar]

Hi.

I have a machine that has two network cards, one to access local office
network (small office with 8 -10) machines and another for accessing
internet - 64kbps broadband - through a service provider.
One network card is assigned static ip 192.168.0.1 with subnet 255.255.255.0
for local network and the other is one more static I P given by the
broadband service provider.
Internet is connected when required through the dialer given by the service
provider. It is not "always on".
The problem is when I connect to the Internet, I am unable to browse my
office network to share files to & from the local machine. I have to reboot
the system to access the local office network. Then I can share between my
system & other systems.
This is giving a lot of inconvenience as sometimes I need to access both
local network and internet at the same time.
Why is this happening and how can I change this behaviour? I need to know
how to make both the Internet & Local Network work at the same time.
The firewall setting is on and also Zone alarm basic version is installed. I
have disabled the file & printer sharing in the properties of the Internet
LAN card while the other is enabled.
Any solution/workaround is appreciated.
The machine is Windows XP Professional, PIV, 1GB RAM, 80GB HDD.

Another problem - how to convert a server into workstation?? One system has
server (Windows NT 4.0 Server) installed and other systems cannot access
this system while the server system can access all the other systems. Is
formatting & reinstall only way? Any other solutions??
Thanks in advance.

Do you have two default gateways in the computer? Post the result of ipconfig /all here may help.

There is one gateway in the computer, for the internet LAN card. The other one does not have any gateway..
Both internet & the Local network used to work fine till about couple of months back. But had to reformat the system and reload the OS. After reinstall the OS, this problem started to occur.
I will post the ipconfig info as soon as possible..
