Or perhaps the DTU is cycling a lot and it *is* acknowledging it, so on cycle 1 it gets address from server 1, and on the next it gets it from server 2.

I've seen that before with multiple servers on private interconnects and a CAM script that was falling though.

I'd say the problem here is you have two DHCP Servers on the same network giving out IP's. The Sun Ray is not getting two IP's but two servers answer the the initial request and Sun Ray accepts one of them. The other one that got offered will expire when the lease is done.

That sounds like a bad DHCP server implementation.
If the server sent an OFFER but never received
a REQUEST for it, the server should feel free to re-offer the
address within a relatively short period.

Unless of course the Sun Ray cycles before the lease expired and sends out the DHCPReq again. If the DTU just stays up, it will renew it's lease w/ the DHCP Server it got the address from.

If you already have a DHCP server on the network, why are you having the Sun Ray Server give out IP's?

We are deploying several Sunray DTUs on a public network.  The DTUs get
their IP addresses assigned from a central DHCP server, not the Sunray
server. It appears that on several occasions the DTUs seem to pick up two
IP addresses.  This has been verified by examining the arp tables on the
router.


We are running SRS 3.1 on Solaris 9 in a failover configuration.   The
DHCP server is Microsoft DHCP on Windows 2003 server.


Any ideas as to what might be causing this problem?


Thanks,
