Duplicate IP's with RDM 4.11 installed

[Seabz420]

DHCP - Win NT 4.0
RDM - Win Server 2K3

We've been experiencing a problem where systems are being delivered duplicate IP addresses. From what I understand, our DHCP server issues an IP, then at night Director boots the systems to the network and RDM delivers a new IP address. Turns out RDM is issuing IP address that our DHCP has already issued, causing problems when people log on (duplicate IP errors). Is there some way to have the RDM use our existing DHCP server do deliver IP's when requested? Or is there something that we've over looked?

Our clients all have static IP's (for internet tracking purposes), so we can't have IP's jumping around.

Thoughts? Ideas?

Yes...Take a look at the RDM Installation Guide (Ch 4).

Off topic question and I hope nobody minds but I have been trying to find RDM on IBM's web site to download but have been unsuccessful. I can only find where you can buy the media cdrom for 50 bucks. I have the right to own the software. The only reason I dont have is because my company took over a contract and the previous contractors did not leave the cdrom. Any ideas where to download it. IBM says I gotta buy the cdrom again.

Catorze,
Which is the management server? The server that has IBM Director Server installed, I assume.

Here's a better question:

If setting the multicast IP to the same IP range that our subnet uses (is that possible?), then would that produce the duplicate IP problem?

Stiddy - RDM is not for download, it's for purchase.

Seabz420 - Yes. The IBM Director/RDM server. Bottom line is that you should only have one DHCP server issuing addressses in a range on a network. Whether you choose to keep the existing one or have RDM do it, there must only be one on a single network.

If you should only have 1 running, then where do you tell Director to use the existing DHCP. The two options you get are: "Yes, DCHP installed on the management server" and "No, DHCP is not installed on the management server". I'm assuming that by saying No that you are telling RDM to use it's DHCP system, and vise versa. What about if DHCP is installed on another server on the subnet? I can't find any place to point RDM to that DHCP server.

 

[catorze]

Partly correct. By saying "no", you're indicating that the DHCP server is running somewhere else. When installation is complete, you have to run the batch file PXEDHCP.BAT as indicated by the popups you received during installation - didn't really read them did you ) The installation & configuration guide also details what's required.

I thought that you only run Option 60 if DHCP IS installed on the management server. In our case, DHCP is not installed on the management server...
