Hi Greg,

first of all thanks for the fast reply!!

1. Get a new PC, install - let´s say - Fedora Core, install Apache,  Perl, PHP and Koha. Connect this system to the Windows NT server and  be able to provide access to Koha to all 50 workstations of the  office. There is no need to provide public access (yet), so I think  the system has not be the latest server hardware, but a normal  workstation would do.
But: is it possible to connect the Linux PC to the Windows NT server  and enable it to be accesible for ALL Windows workstations of the  office?!?

You do not have to 'connect' the Linux server to the NT server. You would assign the Linux Koha server an IP address and make an entry into the internal DNS so that when people browse to http://library.your.company.name/ they get to the OPAC interface.

Okay, but I still will have to integrate the system into the NT network, or am I misuinderstanding something?
I think this should work via Samba, or are there any other possibilities? I expect that I won´t be able to connect the Linux server by other means, or are there?

If you mean that you want the host to be part of a Workgroup or Domain, then you will have to use Samba. However unless you are using this host as a workstation (which you shouldn't be) then there isn't really a requirement to do this.

However if this host is only going to be used for Koha, then all it will need is an IP address and a DNS entry.

For administration, connect to the host with SSH which will give you a command prompt on the host. You will be able to use a web browser on a workstation to visit the OPAC/Intranet webpages.

I appreciate very much every thought on this topic; if anyone has a  good weblink for a NT/Linux-network introduction I would be grateful  as well.

The Linux Documentation Project has several HOWTOs on networking for Linux, here is one:

Thanks for this great link.
Looks very user-friendly, so I will do my homework!

Have fun!
