RIS on separate server than AD/DHCP (error PXE-E55)

Here's our setup:

Server 1: Primary DC and DHCP
Server 2: RIS
Server 3: DNS (Solaris-based)

When booting a client via PXE, I get the following error:

PXE-E55 ProxyDHCP - No reply to request on port 4011

I've made sure the RIS server is "authorized" in DHCP. I did this by
adding it (Server 2) to the authorized servers liston Server 1.

Common suggestions that I've already tried:

- Making sure the server is "authorized in DHCP"
- Server 2 is multi-homed. I've disabled the 2nd NIC (which is on
another network). No dice.
- There are no firewall rules or "in-between" routers to deal with,
the machines are connected among switch's with no ACL's between them.
- I've increased the ResponseDelay parameter
(HKLM\SYSTEM\CurrentControlSet\Services\BINLSVC\Parameters) without
luck.
- On Server 1's DHCP config, I've manually set DHCP option 66 to
return the hostname of the RIS server.

I can't remember if there's anything else important I've done/tried.
I DO have some packet traces that I'll post below. These were
recorded with Ethereal on Server 2 running in promiscuous mode
filtering on Server 1, Server 2, and PXE client MAC addresses. As
such some packets (any non-broadcast) between Server 1 and the client
aren't recorded. The results are pasted at the end...

Basically, it goes like this:

Client => DHCP Discover (Source: 0.0.0.0 Dest: 255.255.255.255)
Server 1 => DHCP Offer (Source: 12.11.14.10 Dest: 255.255.255.255)
Client => DHCP Request (Source: 0.0.0.0 Dest: 255.255.255.255)
Server 1 => DHCP ACK (Source: 12.11.14.10 Dest: 255.255.255.255)

One of the things I'd like to get my hands on is a detailed document
describing how RIS works, specifically WHEN each component does its'
part. For instance, after the above exchange, is the client supposed
to send a request to Server 2 (RIS)? Or is RIS supposed to receive a
communication from the DC/DHCP telling it that the client is
attempting to PXE boot?

Likewise, none of the DHCP-related packets the DHCP server sends
contain option 66 or 67, which I'd guess are "important". Is this
because these are supposed to be supplied by the RIS server in a DHCP
response?

I also turned on debugging for the RIS service and am pasting the
corrosponding results that were compiled at the same time I took the
Ethereal trace. It just doesn't look like it's DOING anything but
it's not really erroring out either! The two things I don't quite
understand with it are the ldap_count_entries returning 0 as well as
the "Sending response to = 255.255.255.255" unless that's a DHCP-type
response it's sending?

I'm literally at the end of my rope here and don't know what to do!
Any suggestions will be helpful, thanks.

Looks like the client receives the "next-server" option set to
12.11.14.10. Isn't this ip your dhcp server? The next-server option
should have the ip address of server 2.

Try using ip address instead of hostname in dhcp option 66

Here's our setup:

Server 1: Primary DC and DHCP
Server 2: RIS
Server 3: DNS (Solaris-based)

When booting a client via PXE, I get the following error:

PXE-E55 ProxyDHCP - No reply to request on port 4011

I've made sure the RIS server is "authorized" in DHCP. I did this by
adding it (Server 2) to the authorized servers liston Server 1.

Common suggestions that I've already tried:

- Making sure the server is "authorized in DHCP"
- Server 2 is multi-homed. I've disabled the 2nd NIC (which is on
another network). No dice.
- There are no firewall rules or "in-between" routers to deal with,
the machines are connected among switch's with no ACL's between them.
- I've increased the ResponseDelay parameter
(HKLM\SYSTEM\CurrentControlSet\Services\BINLSVC\Parameters) without
luck.
- On Server 1's DHCP config, I've manually set DHCP option 66 to
return the hostname of the RIS server.

I can't remember if there's anything else important I've done/tried.
I DO have some packet traces that I'll post below. These were
recorded with Ethereal on Server 2 running in promiscuous mode
filtering on Server 1, Server 2, and PXE client MAC addresses. As
such some packets (any non-broadcast) between Server 1 and the client
aren't recorded. The results are pasted at the end...

Basically, it goes like this:

Client => DHCP Discover (Source: 0.0.0.0 Dest: 255.255.255.255)
Server 1 => DHCP Offer (Source: 12.11.14.10 Dest: 255.255.255.255)
Client => DHCP Request (Source: 0.0.0.0 Dest: 255.255.255.255)
Server 1 => DHCP ACK (Source: 12.11.14.10 Dest: 255.255.255.255)

One of the things I'd like to get my hands on is a detailed document
describing how RIS works, specifically WHEN each component does its'
part. For instance, after the above exchange, is the client supposed
to send a request to Server 2 (RIS)? Or is RIS supposed to receive a
communication from the DC/DHCP telling it that the client is
attempting to PXE boot?

Likewise, none of the DHCP-related packets the DHCP server sends
contain option 66 or 67, which I'd guess are "important". Is this
because these are supposed to be supplied by the RIS server in a DHCP
response?

I also turned on debugging for the RIS service and am pasting the
corrosponding results that were compiled at the same time I took the
Ethereal trace. It just doesn't look like it's DOING anything but
it's not really erroring out either! The two things I don't quite
understand with it are the ldap_count_entries returning 0 as well as
the "Sending response to = 255.255.255.255" unless that's a DHCP-type
response it's sending?

I'm literally at the end of my rope here and don't know what to do!
Any suggestions will be helpful, thanks.

Johan,

Thank you for the reply. That is definately what it's doing. I didn't
realize what the next-server option was used for and especially didn't know
what it "should" be. I ran a packet trace on Server 1 (DHCP) and it became
much clearer. Here's what happens (as far as I can tell):

Client => DHCP Discover
Server 1 => DHCP Offer
Client => DHCP Request
Server 1 => DHCP ACK
Client => DHCP Request (I believe this is where it's trying to
contact the PXE server because the source is the actual IP instead of
0.0.0.0). But you're right, it's sending it to the DHCP server, not the RIS
server. It's also different because it's trying to hit port 4011 (PXE).

After this, Server 1 replies with an ICMP Destination unreachable response.
The client then releases the DHCP address and tries all over again. It does
this quite a few times.

So my problem (at least a major one) is that the DHCP isn't setting the
correct next-server IP.

I did try setting the option 66 to the IP as well as the hostname with no
luck. I even restarted the DHCP service and trying it (in case those values
aren't dynamically accessed). I even tried restarting the service using the
hostname again in option 66.

I'm going to start my search anew knowing what the specific problem is now.

If anyone has pointers on forcing Windows DHCP to return a specific
next-server variable, I'd be very happy if you filled me in! :-)

John
 
please refer to technical guide to remote installation services (I have it
from technet) and there is nice schema of interactiont betweam DHCP, RIS and
the client.

John said:
Here's our setup:

Server 1: Primary DC and DHCP
Server 2: RIS
Server 3: DNS (Solaris-based)

When booting a client via PXE, I get the following error:

PXE-E55 ProxyDHCP - No reply to request on port 4011

I've made sure the RIS server is "authorized" in DHCP. I did this by
adding it (Server 2) to the authorized servers liston Server 1.

Common suggestions that I've already tried:

- Making sure the server is "authorized in DHCP"
- Server 2 is multi-homed. I've disabled the 2nd NIC (which is on
another network). No dice.
- There are no firewall rules or "in-between" routers to deal with,
the machines are connected among switch's with no ACL's between them.
- I've increased the ResponseDelay parameter
(HKLM\SYSTEM\CurrentControlSet\Services\BINLSVC\Parameters) without
luck.
- On Server 1's DHCP config, I've manually set DHCP option 66 to
return the hostname of the RIS server.

I can't remember if there's anything else important I've done/tried.
I DO have some packet traces that I'll post below. These were
recorded with Ethereal on Server 2 running in promiscuous mode
filtering on Server 1, Server 2, and PXE client MAC addresses. As
such some packets (any non-broadcast) between Server 1 and the client
aren't recorded. The results are pasted at the end...

Basically, it goes like this:

Client => DHCP Discover (Source: 0.0.0.0 Dest: 255.255.255.255)
Server 1 => DHCP Offer (Source: 12.11.14.10 Dest: 255.255.255.255)
Client => DHCP Request (Source: 0.0.0.0 Dest: 255.255.255.255)
Server 1 => DHCP ACK (Source: 12.11.14.10 Dest: 255.255.255.255)

One of the things I'd like to get my hands on is a detailed document
describing how RIS works, specifically WHEN each component does its'
part. For instance, after the above exchange, is the client supposed
to send a request to Server 2 (RIS)? Or is RIS supposed to receive a
communication from the DC/DHCP telling it that the client is
attempting to PXE boot?

Likewise, none of the DHCP-related packets the DHCP server sends
contain option 66 or 67, which I'd guess are "important". Is this
because these are supposed to be supplied by the RIS server in a DHCP
response?

I also turned on debugging for the RIS service and am pasting the
corrosponding results that were compiled at the same time I took the
Ethereal trace. It just doesn't look like it's DOING anything but
it's not really erroring out either! The two things I don't quite
understand with it are the ldap_count_entries returning 0 as well as
the "Sending response to = 255.255.255.255" unless that's a DHCP-type
response it's sending?

I'm literally at the end of my rope here and don't know what to do!
Any suggestions will be helpful, thanks.
