Remote connection randomly

[gvielliard]

Hi all,

I am facing a strange problem:

I installed for a training session 10 PC. Each of them has SQL Server 2000 installed localy on it. Each of them has its own local Server.
These PC are on the same network.

And, I don't know why but after rebooting them, they changed randomly the settings. For example in the SQL Server Group of PC A, it is not the Server A anymore but Server C. In my group of 10 PCs, 6 changed their settings by themselves, 4 kept their original configuration.

Does anybody experienced this problem and has a solution or an idea of what is going on?

Is DHCP enabled on all of these PCs?

Hi,
What is DHCP?
BTW, I have something else which is strange:
the autentification changes as well alone, I want them to be ahtentified by the SQL login and password. And I don't know why and how, but it happens it changes to Windows NT autentification...
Thanks
Gilles
