Hi!
I am new to this forum but have been working with Linux (RHEL) at my job for a few months now and have played around with it some at home before that.

I am currently working on a triple boot machine that has 3 hard drives (one OS per HDD) and am trying to use our current kickstart images at load the first 2 HDDs (RHEL3 & 4).

So here is what I am running into so far:
I kickstart the 2nd HDD (RHEL4), login and everything works great :-)
I kickstart the 1st HDD (RHEL3), login and everything works great :-)
I edit the grub.conf file to boot to the 2nd HDD, restart and log back into RHEL3 - still works fine

Heres where it gets funky: I restart - grub into RHEL4 login works fine
Restart and grub into RHEL3 - eth0 fails to initiate and can't login.
I can restart - grub into RHEL4 - still works perfectly fine.

We use an LDAP Server for logins (no eth0 = no login)

So my question is: What does loading RHEL4 change in RHEL3 that it can't initiate eth0?

I know this is only involving a dual boot so far but I'm am sure there will be more questions along the way.
